PRODUCT HOW-TO: Implement an MP3 audio decoder with the ARM Neon Multimedia extensions
How the ARM Cortex-A8's NEON multimedia instruction extensions can be used to implement the MP3 audio algorithms on Freescale's i.MX51 mobile media processor platform.
Using an FPGA to tame the power beast in consumer handheld MPUs
Shorter product lifecyles and lower volume consumer product families have led designers increasingly to turn to the FPGA for handheld-product development. But doing so requires grappling with new challenges in terms of area, speed and power.

MOST networks require the 'most' innovatively designed junction boxes
Tremendous market acceptance of MOST technology within the automotive industry is driving OEMs and CEMs, developing and supplying multimedia and infotainment systems for cars, to explore new ways to increase manufacturing efficiency and reduce the associated production costs
Challenges in automotive radio design
In terms of in-car features, customer expectations are driving the integration of more electronic devices. In addition, new technologies and automotive operational requirements create severe design challenges for suppliers.
Building an in-car MP3 player using Altium's NanoBoard
Doug Gibbs, a Senior Staff Software Engineer at Xilinx, was the runner up in the Altium Design Competition. Doug's idea is to build an in-car stereo MP3 player with an 802.11 connection to allow networking with a user's home PC. When you drive into the garage, you're the system will automatically sync to the PC and update all of the music you've downloaded.
