SPACE WATCH
NASA’s Marshall Space Flight Center in Huntsville, Ala., completed a series of cryogenic tests on six James Webb Space Telescope beryllium mirror segments at the center’s X-ray & Cryogenic Facility. During testing, the mirrors were subjected to extreme temperatures dipping to -415 degrees Fahrenheit, permitting engineers to measure in extreme detail how the shape of the mirror changes as it cools.
The mirrors are designed to stay cold to allow scientists to observe the infrared light they reflect using a telescope and instruments optimized to detect this light. Warm objects give off infrared light, or heat. If the Webb telescope mirror is too warm, the faint infrared light from distant galaxies may be lost in the infrared glow of the mirror itself. Thus, the Webb telescope’s mirrors need to operate in a deep cold or cryogenic state, at around -379 degree Fahrenheit. more> http://bwbx.io/fA1W

For ARM, It's Server Side Up
Blogs On Semiconductor - Thu, 07/29/2010 - 18:00
Ian Drew, executive vice president of marketing at ARM Holdings (s armh), a Cambridge, U.K.-based company that makes semiconductors powering a majority of the smartphones, tablets, 70 percent of world’s hard drives and half the world’s printers, is on a whirlwind tour of Silicon Valley. And what everyone (including me) wants to talk to him about is servers, or rather low-power server chips that can power the data centers of tomorrow.
With this foray into the fast-growing data center business, the company, which can trace back its roots to Apple Computer, is slowly becoming a bane to Intel’s existence. And the funny thing is, it does so not by making chips, but instead it develops technology and licenses it to all comers.
Some special companies — Qualcomm (s qcom), Marvell (s mrvl) and Infineon (s ifx) — get access to all of ARM’s entire technology stack, so they can build their own chips which in turn compete with Intel. The latest company to sign-up: Microsoft (s msft), the long time partner of Intel (s intc) and the other half of the ‘Wintel’ monopoly. What Microsoft will do with ARM’s technology remains to be seen, but it is a notable move nonetheless. It is a sign that the company is killing it.
Check out their American Depository Receipts: at the close of trading they were up nearly 165 percent over past twelve months. In the second quarter of 2010, its revenues jumped 42 percent to $150.3 million versus $105.5 million in Q2 2009. Earnings per share leaped 147% percent to $2.34 a share versus 95 cents a share it earned in a year ago quarter. From the looks of it, things seem to be going well for these guys.
The main reason ARM has done so well is because it has focused on developing low-power technologies that it licenses in turn to others, thus eschewing the headaches that come with manufacturing and selling your own chips. More importantly, ARM as a company sits at a unique position in the technology ecosystem. Because it licenses its chip technology to others, it has a good idea of what kind of products are coming to market, how well certain type of products are doing and more importantly where the industry is headed. In short, it talks to chip makers, device makers and these days even software companies that are developing software for these consumer devices.
And what Drew and his cohorts are seeing is a radical revolution in the data centers. “While the x86 world focused on pure megahertz, we have focused on the megahertz per milliwatt,” Drew said during our conversation earlier today. “We focus on quarter-to-half milliwatts as a key metric.” Most of the new devices such as the iPhones don’t have heat sinks in them, he joked.
“If you look at our heritage (of low power chips) it makes perfect sense for us to be looking at the servers and the data centers,” said Drew. With “cooling” making up nearly half the capital expenditure and almost two-thirds of the operation expenses, Drew said power is going to be a bigger part of the conversation.
“Everyone is using the Web and the Web is more demanding today which means all of the stuff is going to run through data centers,” he noted. “Two things are very clear: there is going to be a lot of data and need for less power.” By getting the world to buy more edge devices (iPhones, iPads etc.), ARM is at the same boosting demand for back-end computing infrastructure. Now by diversifying into the data center server business, it can make more money selling its low-power chip technology to server makers. In other words, ARM wins on both sides of the trade.
Stacey, in a post earlier this year noted:
The news shouldn’t come as a surprise to our readers, since I profiled Smooth-Stone, one company trying to build low-power servers earlier this month, and in that same post pointed to ARM’s server ambitions. And it’s not just startups that are interested in using the low-power ARM architecture inside data centers, either. Google recently acquired a secretive startup called Agnilux that was rumored to be making a server with the ARM architecture.
We also reported on a Microsoft job listing that sought a software development engineer with experience running ARM in the data center for the company’s eXtreme Computing group. For the last couple of decades, Intel’s x86 chips have gained dominance in the data center, but as power considerations begin to outweigh the benefits of a cheap, general purpose processor, other chip makers have started to smell blood. Nvidia is pushing its graphics processors for some types of applications, while Texas Instruments is researching the use of DSPs inside servers.
But don’t expect this to happen overnight, Drew cautioned. “We are going to see some pilots over next year, but this is a long term initiative.” He believes that this long, continuous transition to lower-power server chips is going to take between three to five years. When I asked Drew what are those pilots, he declined to comment. From our reporting, we can easily tell you Microsoft, Smooth Stone and Marvell are experimenting with ARM-based server processors.
And while ARM tries to build a server business, the company, Drew said has plenty on its plate. For instance, the upcoming/next generation Cortex-A class processor codenamed “Eagle”, which is likely to help redefine the smartphone landscape again.

Earnings... Confusion Reigns at MEMC (WFR)
Blogs On Semiconductor - Thu, 07/29/2010 - 13:40
MEMC Electronic Materials, Inc. (NYSE: WFR) is one of those companies which seems to be just stuck between a rock and a hard place. Tonight’s earnings will only reflect that further. The materials maker for semiconductors wafers and solar wafers reported earnings of $0.06 EPS, but that figure includes items of $0.10 per share,versus a Thomson Reuters expectations of $0.09 EPS. Revenues were $448.3 million versus $466 million expected from Thomson Reuters.
As far as 2010 guidance, MEMC expects to exceed its earlier revenue guidance of $1.75 billion to $1.85 billion, but it sees earnings below its previous guidance of $0.70 to $0.80 EPS. Thomson Reuters has estimates of $0.66 EPS on revenues of $2.04 billion. It sounds like margin pressure and we’ll see more data after the earnings conference call.
With shares off about 90% from the old highs, MEMC is a stock where the reaction can go either direction depending upon which way the wind blows on a given day.
So far, MEMC is a turnaround which has not been able to turn around. The old hopes for a buyout were mostly tied to the notion that the stock was down so much from its peak. Picking stocks solely on buyout hope is often dangerous, and all companies should be bought on the merits of the business not because shares are down considerably from their peak.
Shares closed down 2.1% at $11.26 in regular trading today, and the stock is down by 6.5% at $10.53 in the after-hours trading session. Its 52-week trading range is $9.51 to $19.31.

Zarlink turnaround continues as revenue targets exceeded
Blogs On Semiconductor - Thu, 07/29/2010 - 10:36
Kanata-based Zarlink Semiconductor beat its revenue targets by 18 per cent year-over-year in first-quarter results announced on Thursday.
The firm’s revenues reached $58.7 million, which exceeded their earlier revenue guidance of between $57 million and $58.7 million.
Zarlink stated this was due to “increasing customer demand across all core segments of the business,” particularly in communications products, where revenue grew by $3.9 million, and medical products, up $1.3 million.
Basic earnings were at $0.08 per share and $0.07 per diluted share.
Zarlink earlier sold its optical-products unit, which generated net proceeds of $13.5 million.
The firm said it expects to see more demand for its next-generation carrier chipset products, which includes voice-over-broadband and new efficiencies in wireless to improve the speed.
Customers such as Ciena Corp. and Teias Networks have integrated Zarlink’s ClockCenter timing platform into their video products, allowing them to lower power consumption and simplify the design, Zarlink stated.
“Q1 was a very strong start to fiscal 2011,” stated president and chief executive Kirk Mandy.
“While capacity concerns are impacting the global semiconductor industry, we are working closely with our foundry partners to ensure we continue to meet delivery commitments as end-market demand for our products escalates.”
As part of its work beyond semiconductor, the company grew its medical revenues to $6.6 million, from $5.3 million in the fourth quarter of fiscal 2010.
The money came from shipments of wireless radio modules that were allowed for medical applications after approvals from the United States’ chief medical approvals body, the Food and Drug Administration.
However, year-over-year revenue fell from $9 million in Q1 2010 to the $6.6 million posted in Q1 2011.
Zarlink further made the following forecasts for Q2 2011:
- Revenue between $58.5 million and $60.5 million;
- Gross margins between 50 per cent and 51 per cent;
- Operating expenses between $20.5 million and $21.5 million, excluding amortization of intangibles;
- Q2 earnings of $0.03 to $0.05 per share, excluding foreign exchange fluctuations.

New Product Execution - It's Just not Good Enough
Blogs On Semiconductor - Thu, 07/29/2010 - 01:40
New Product Execution is never quite good enough, although there is certainly a continual business emphasis demanding better. There may be small pockets where new products efforts scream success, although the overall effort frequently comes in with a "C" grade or worse. How's your organizations new product execution grade? No, you can't grade yourself; the only grade that matters is the one from the business GM or the customer.
There is a broad belief that if new product execution is failing it's because the development team does not have enough passion to get the job done. I strongly disagree with this narrow-minded perception. My long-term observation is that if execution is failing, it's because leadership has failed the team. Leaderships role is minimally to guide the team to a better tomorrow through the seeking and addressing of systemic issues that are routinely impacting execution. I firmly believe that a key role of leadership is the enablement of an environment that spawns continuous improvement.
The picture to the right is a list of common objectives and challenges that will pave a path to execution excellence, as each item is addressed. Click on it, print it and hang it on the wall as guide to attaining an "A" grade in new product execution. Utilize the concepts below to further hone a strategy for leaving average execution performance in the dust.
An Execution Strategy is Missing
News flash - new product execution is lacking a strategy simply because of a misplaced belief that there is one. That ghost strategy is actually a rigid tactical approach masquerading as an execution strategy. An authentic strategic approach will minimally include:
- Regular questioning of why things are done as they are.
- The regular application of learning from past products.
- A participant scope that includes all functional areas.
- Embraces dynamic planning.
- A shared vision of what ideal execution looks like.
- Cover all activities from concept through revenue.
Execution Scope is far too Narrow
At what point does new product execution begin? Most would be apt to identify the phase where significant design activity commences. I disagree; execution begins when that first twinkle of an idea begins to glow, where a product concept is born. A misguided assumption that execution begins with later activities allows the critical early tasks to flounder, avoiding the crisp management required to drive efficient closure. The "let's think about it" queue must be considered as execution, with all the sense of urgency and accountability that is expected for any project phase. The deliverables, time line and objectives must be managed from the very beginning.
Unacceptable New Product Success Ratio
How many products fail at meeting business case profit? Those losers will certainly eat up the ability to execute well on the successful products. Any product that is not a financial success must be scrutinized. The root cause for allowing such products to continue marching forward in the face of eventual failure must be well understood. There is gold in the analysis of failed products and significant mining will be required to gain access to it. Throw on your miner hat, turn the light on extra bright and go about finding the golden nuggets of information that will enable an improved strategy for approving and monitoring new products.
Failing to find what is Unknown
I have been talking about unknowns since the first day I opened the doors for business and it still baffles people when I talk about them. An unknown is a masked barrier to smooth, orderly and predictable execution in a new product effort. If you are not specifically looking for unknowns and removing them, your new product execution will have an element of time-wasting rework. If you want a higher level of predictability, go out and find what you don't know, and do it regularly. "Those that know, know they know. Those that don't know, don't know they don't know"

Apple Keeps Intel in New Powerful PC (AAPL, INTC, AMD)
Blogs On Semiconductor - Wed, 07/28/2010 - 05:08
If you have been keeping up with trends from Apple Inc. (NASDAQ: AAPL), it is no secret that the company is trying and trying to do what it can to have its own technology inside its popular products. After all, if a company has 50% profit margins in the products that are the guts of your key products, why not. Apple has announced its newest and “most powerful” iMac with a new processor architecture and faster graphics for its all-in-one computer. Intel Corporation (NASDAQ: INTC) is included here, but so is its distant number-two rival Advanced Micro Devices, Inc. (NYSE: AMD).
As far as Intel is concerned, it offers the Intel Core i3, i5, and i7 processors with an advanced architecture and new benchmarks for the iMac performance with quad-core power based on the 32-nanometer process technology. For AMD, its ATI Radeon graphics processors are independent of the CPU and there are various models here.
Intel has been one to watch because the processors for iPads and iPhones are not using Intel processors. Apple has been designing its own architecture for processors in a grow-your-own model.
Apple has 4 models being launched: 21.5 inch with a 3.06 GHz at $1,199.00; 21.5-inch with a 3.2GHz at $1,499.00; 27-inch with a 3.2GHz for $1,699.00; and 27-inch iMac with 2.80 GHz at $1,999.00.
There are some who have speculated that Apple will one day use its own architecture and own processors for most of its products. Whether or not that ever comes to be the case is another matter. For now, Intel is still getting to benefit from at least some of Apple’s product growth.

The race to organise television
Blogs On Semiconductor - Tue, 07/27/2010 - 18:01
Economist – Not so long ago finding a TV programme was easy. You opened a newspaper, looked at what the three or four broadcasters were showing that evening, and made sure you got home in time. The rise of multichannel television has complicated matters. BSkyB, a British satellite broadcaster, offers 505 channels, not including radio or pay-per-view films. Pay-TV outfits are pushing on-demand films and television shows, either bundled with subscriptions or à la carte. And people are recording more TV.
Whereas technology firms tend to view television sets as large computer monitors, TV folk regard them as distinct in two important ways. First, they think, viewers do not want too many options. A search that turns up thousands of programmes is pointless, says Fred Amoroso, Rovi’s CEO: people want small lists of relevant choices. more> http://tinyurl.com/2btazpj

Study note of LabVIEW FPGA (2)
Blogs On Semiconductor - Tue, 07/27/2010 - 17:51
After a few days of using LabVIEW FPGA, here are some thoughts:
It IS much more convinient programming in LabVIEW. When I came up with some problems, I spent very few time checking the logic rather than considering the syntax (which is fine) and the logic cycle (which is a nightmare);
The conversion of bitstream file takes longer and longer. At first it takes about 6 minutes, a length for pee, as the code grows now it takes about 20 minutes, a time for lunch. I can’t imagine how long it would take when I do a more complex work;
The genenration of clock and signals works:)
We can use Target-Scoped FIFO to perform a Producer-Consumer Loop in FPGA vi;
The size of the array needs to be fixed before hand in FPGA vi;
Loop rates limited by longest path.If the process takes longer than the defined loop timer, it will use the longer one.
Attached is my code. In the producer loop, we generate a train of pulses and push them into a FIFO; in the consumer loop, we pop the data and output it on Connector1/Port0.
I’m somehow preventimg myself from updating the posts too frequently. It’s always harder to write the 10th post (or post after 1 month). I hope I can stick on this.

Broadcom Runs Into Headwinds (BRCM, QCOM)
Blogs On Semiconductor - Tue, 07/27/2010 - 13:30
Broadcom Corporation (NASDAQ: BRCM) appears to have missed the mark on its earnings report, which is now looking much less like QUALCOMM Inc. (NASDAQ: QCOM) earnings last week. There is some confusion on the street over what consensus reports were expecting. Because only loose guidance was not offered, this one should probably be considered somewhat as unfinished business until the conference call.
It posted a record quarter in revenue of $1.604 billion, up 9.7% sequentially and up a sharp 54.3% compared to the same quarter a year ago. The chip designer posted GAAP income of $0.52 EPS, and this is listed as $0.56 EPS on basic income. Thomson Reuters estimates were $1.59 billion and $0.62 EPS. Unfortunately to ad to confusion, outfits like Reuters published consensus revenue data while Barron’s noted that the ‘consensus’ was $0.46 (and noted that $0.62 EPS number ‘everyone else’ was using for the non-GAAP basis).
Guidance for Q3 was put at 6% to 12% revenue growth from this quarter, implying $1.7 to $1.8 billion in revenues. Thomson Reuters had estimates of $1.67 billion for the quarter ahead. Gross margins are expected to remain flat.
Broadcom ended with nearly $2.5 billion in cash and equivalents.
The only comment we have is that this was an exceptional record quarter with strong product demand seen in Broadband and Mobile & Wireless segments with the growth and margins driving profitable growth in 2010. Scott McGregor, its President and CEO said, “We anticipate that increasing demand for communications solutions and market share gains will drive strong revenue growth for Broadcom in the third quarter.” Unfortunately, that tells us very little above and beyond the very loose data offered here.
Shares closed 1.8% lower at $37.53 versus a 52-week range of $25.76 to $38.41, but shares are currently down 3.3% at $36.17 in the after-hours session.
UPDATE AT 6:00 PM EST: Broadcom’s press release was not a usual report compared to many earnings reports. The company said in a telephone call that they beat earnings expectations, and there is still confusion over the company’s story versus what we had seen as consensus and versus what others had seen as consensus at $0.62 EPS on a non-GAAP basis. It seems that Broadcom did not like that its stock was down initially, and perhaps it should clarify its GAAP versus non-GAAP data more clearly to avoid repeat confusion in the future. Shares were down over 3% initially, but shares are now indicated up 1% in the after-hours prints.

MediaTek is Gunning for Qualcomm
Blogs On Semiconductor - Tue, 07/27/2010 - 07:15
Qualcomm has much to fear from Intel (s intc), which is attempting to gain a foothold in the mobile market while Qualcomm (s qcom) has turned its focus upmarket to computers. However, news out today from MediaTek should have them even more worried. MediaTek, a Taiwanese baseband provider that currently is ranked No. 2 in the world, has signed an agreement to license LTE technology from NTT DoCoMo and work with the Japanese carrier to build out an LTE-compatible platform.
MediaTek, which has become a mainstay radio provider in emerging economies, is moving upmarket, following the spread of 3G and smartphone adoption. Earlier this month MediaTek joined the Open Handset Alliance – the group pushing the Android (s goog) operating system forward. In the release, MediaTek said:
Building on the success in delivering feature-rich multimedia experiences on various mobile platforms, MediaTek enables cost-effective AndroidTM -based smart phones by delivering high-quality; full system solutions that further reduce the barrier to entry for broader world-wide penetration of smartphone products that serve the growing appetite for connected devices. Furthermore, working closely with customers, MediaTek is confident to drive wider adoption of smart phones in new and emerging markets.
MediaTek is finding success in emerging markets, where its baseband chips for 2G wireless networks are cheap, and thus enable less-expensive handsets. Qualcomm doesn’t really have a play in the 2G standards, except to ensure that its 3G chips can work with the older technology. However, MediaTek is clearly not going to stand by and watch its core base of 2G customers transition to smartphones on 3G and 4G networks, so the newly licensed LTE technology and support for Android will position it against Qualcomm in the coming years.
Many emerging markets are in the process of 3G deployments, with China making a rapid transition and India recently conducting its long-awaited spectrum auction. Despite its wins with application processors in high-end Android devices like the Droid or the HTC Incredible, Qualcomm’s Snapdragon chips are still an immature business compared with the revenue brought in by its cheaper integrated chips that provide both a radio and the application processor. It’s those cheaper chips that will be threatened as MediaTek matures.

In many markets, there is what marketers call a “gorilla” - a company with a commanding market share that controls the way the ball rolls in that particular segment. In HDL simulation for FPGAs, one could argue that ModelSim from Mentor Graphics has historically been the gorilla - with a dominant market share and OEM deals with most of the major FPGA vendors that allow them to be the first simulator out of the box when new designers start working on an FPGA design. Aldec, Inc. has always played the role of spoiler to ModelSim’s gorilla. From the sidelines, it appeared that Aldec generally employed the “fast follower” strategy - running close behind with new features and innovations and working to win on price. The strategy worked relatively well for Aldec, who has kept a strong market share for over a decade. ....

Leveraging FPGA co-processors to optimize high-performance digital video surveillance systems
Blogs On Semiconductor - Tue, 07/27/2010 - 04:36
Source: MangoDSP
Digital video surveillance systems now offer enhanced capabilities that make them a compelling alternative to traditional analog systems. In addition to offering advanced video compression techniques such as MPEG-4 and H.264, digital video surveillance systems can be augmented with algorithms such as stabilization, video motion detection, watermarking, and encryption. This article highlights the benefits of these new technologies and their optimal implementation on a platform using a combination of digital signal processors and FPGA coprocessors.
Digital video surveillance systems now offer additional capabilities that make them an effective alternative to traditional analog systems. In addition to offering advanced video compression techniques, such as MPEG-4 and H.264, these systems can now be augmented with algorithms, such as stabilization, panorama, and video motion detection.
Typical requirements for commercial video surveillance systems include the following:
- Support for one to16 cameras
- Advanced video compression such as MPEG-4, JPEG2000, and H.264
- Low latency encoding (one to three frames)
- Simultaneous view and record at different frame rates
- Encoding resolutions ranging from common intermediate formats (approximate VCR resolution) up to D1 (approximate DVD resolution)
- Video rates ranging from two frames per second (home security) up to 30 frames per second, such as those casinos use and other premium type systems
Enhancing video surveillance quality
Given a fixed bandwidth, several different methods including advanced video compression, defining the region of interest, image stabilization, and panorama can improve video quality. The most common video compression technique used today is MPEG-4. However, developers are beginning to adopt new compression techniques, such as H.264 and JPEG2000 to improve video quality, significantly enhancing detection capabilities.
