ARM Cortex-M0 on thin board

Note: This was originally posted on 23rd February 2012 at http://forums.arm.com

Hello to all

This is my first post - I'm looking forward to talking to all you guys.

I'm not too familiar with this aspects of embedded devices so this might be a basic question about the M0 - I'd like it to fit on a 3'' x 1'' board but the boards I see online - for example on here http://www.keil.com/boards/cortexm.asp - are all 3'' x 3''.

Am I missing something....?

Thanks

It depends on what type of data processing your need to run on the microcontroller.

The Cortex-M0 is well capable of doing general data processing. But if you want to handle image data compression, you might want to use Cortex-M3 for additional instructions on MAC, hardware divide, bit field processing, etc. Or you can even use Cortex-M4 if you want to have faster DCT (it can run faster due to the SIMD feature). The CMSIS DSP library can run on Cortex-M0, Cortex-M3 and Cortex-M4.
