|BAD COMPILERS/ NEW ARM CPUS/ TOYOTA RECALL/ SAKS FLEXES ARRAYS|
|The market is still giving analysts mixed signals about its health withchip salesfalling 9% in 2009 , but also indications of a 30% chipmarket boom in 2010 with chip makersslowly swinging into profitability. And even though ARM reported fallingsales and profits last year , plansare in the works forthree new ARM processor cores in 2010 .
Let's hope that no one has to go through a repeat of anything like Toyota's gaspedal nightmare. Thecompany still can't determine whether it is a mechanical or a softwareproblem. For columnist Michael Barr's take on this issue check out hisblog: “Is Toyota'sAccelerator Problem Caused by Embedded Software Bugs ?”
Among the many design article submissions this week, one that caughtmy attention was “When good compilersgo bad, or What you see is not what you execute ,” on how toget rid of the mismatch between source and compiled machine code andthereby eliminate having to debug the machine code. I learned a lotfrom reading it and I think you will too.
The Design Focus in thisweek is on communications and networking with contributions on differential signal chains incommunications systems design, network engineering foraudio engineers, using SerDesin fourth generation wireless infrastructure and automating networkdesign.

|MARKET NEWS – ARM's weak Q4 outperforms the market
Processor IP licensor ARM Holdings plc (Cambridge, England) reported falling profits and sales for the fourth quarter and full year ended Dec. 31, 2009, but the company said it expects to see improving conditions in 2010.
|MARKET NEWS – Chip makers swing to profitability
Chip makers including Sandisk, Maxim Integrated Products, Cypress Semiconductor and Lattice Semiconductor swung to profit in the calendar fourth quarter of 2009—compared to losses suffered at the height of the downturn in late 2008. But memory technology licensor Rambus posted a wider loss after retroactively recognizing previously withheld royalties in the year-ago period.
|MARKET NEWS – Full-year chip sales fell 9% in 2009, says SIA
Global semiconductor sales were $226.3 billion in 2009, a decline of 9 percent from 2008 when sales were $248.6 billion, according to the Semiconductor Industry Association (SIA). The full-year decline was as had been expected in the last month but much less than had been predicted in the first months of 2009.
|MARKET ANALYSIS – Future Horizons sees 30% chip market boom
The worldwide chip market is set for at two years of more than 20 percent growth and could even hit more than 30 percent growth in a single year, according to Malcolm Penn, the principal analyst and founder of the U.K. market analysis company Future Horizons (Sevenoaks, England).

|EDITOR'S NOTE: Continuing Education|
|ESC Silicon Valley is increasingly the place to get hands-on training. In the past, we told you how to develop your system, then you went back to your lab to make it work. Now, we're bringing that lab to you, giving you the hardware and software you need to design, develop, and debug your system. Find out more here. Note: Early-bird registration expires February 19th.
Finally, as the deployments of 3G Long Term Evolution (LTE) networks accelerate, engineers have their hands full developing and testing handsets to meet the extreme performance requirements these networks demand. Our online course, the Fundamentals of LTE Physical Layer and Test Requirements will take you through the LTE standard and show you how to set up to test user equipment using the latest test systems and techniques.
