I want to use high speed controller for my project,
what about performance of at91rm9200 compared to tms320f2812 in fixed point arithmetic

[pomidor]

not exactly what you want but maybe useful

tell us too what are u planning to do. maybe we could find some other solutions. I think that's important to have good development-simulation tools for you're chosen processor.

i think you should fixed ur plan first

You can not compare ordinary microcontroller and DSP processor. DSP processors are optimized for DSP tasks, while microcontrollers are general devices.
Any microcontroller can perform DSP operations but are MUCH slower doing this because they are not optimized for DSP instructions.
Any DSP processor can also perform ordinary tasks but their price is usually higher.

First define your project specifications, then select components.

I think u should use DSP if u want cheap and eaily plug-in dev.tools
