ANDROID DESIGN/MP3 DECODE/FPGAS TAME MOBILES/DROID TEARDOWN
The recent Consumer Electronics Show no doubt inspired some of thedesign article topics this week:: real time Androidand Linux design , decodingMP3 audio with ARM's NEON multimedia extensions , designing mobiledevices with configurable apps processors , and usingFPGAs to reduce consumer handheld MPU power . We also have anew Under The Hood Teardown of Moto'sDroid iPhone Killer .

My Top Product Picks this week focus on tools and devices for consumer design, including: Newscale's 3 volt piezo motor, TI's 16-bit DSPs, Liguavista's electrowetting desplays,Movidius' Android video-edit processor,Samsung's 30 nm NAND mobile memory,and Microchip's Inductive Touch Development Kit.

Some other design articles I think you will find useful include: combining coding rules and static analysisfor debug reduction, automotive radio designchallenges, doing Goertzel algorithms on fixed point DSP;and how ferrite beans canhelp or hurt circuit performance.

  EDITOR'S NOTE: Continuing Education
Two new online courses you might want to sign up for: Fundamentals of Audio Networking, on the basics of networked audio, and Fundamentals of Storage, on the evolution of storage and the advantages and drawbacks of current storage strategies such as RAID, SAN and NAS.

Also, be sure to register for ESC Silicon Valley, where we've added a second Build Your Own Embedded System (BYOES) track. When you register you get a multi-core board with classes to program it. Then, at a second set of classes, attendees get a Freescale Tower system.
