From: rickee on 11 Oct 2009 09:41 Please tell me what is the cheapest ARM with my request ip. Our company would like to change current audio application to embedded system. after my researching, only 2 way to realize, one is made ASIC Chip (request very long develop time,and huge investment), another is buy ARM with specify IP Core. Requirement for our Audio system: MP3 decode/WMA decode CD/MP3 CD/WMA CD decode including servo control (it should be DSP) USB/SD interface rich interface just like UART/IIC/GPIO for our externtion. I'm a newbee on ARM, cheapest ARM + Linux + MP3 decode core + WMA decode core + CDROM driver + USD/SD driver is it ok? Our forcast can be 100K annual, because our current cost for our solution about $3.00, so we target on the cheapest ARM, which just for Audio but not Video. Thanks a lot!

Not by ARM also ok, I just concern the cost ,stable, and functional. And you recommend is develop by LPC1700? Any company provide the custom ip core? PLease let me kno how to do.

Why do you need arm for that ? Look at what everyone else uses for the same product - most portable Audio systems and use custom power- optimised MP3 decode , and once you have that, an 8 bit core is enough. See the Atmel AT89C51SNDx series for one example. -jg

There are well known hardware and software libraries for mp3 decoders. If you do the IDCT in hardware, you can do the rest in a 8bit µC. |
