Re: mobile processors

TI DSPs with I think the Programmers Workbench from TI
Blackfin with the Visual DSP toolset from ADI
ARM with IAR or ARM Tools
I believe there are some mobiles with Freescale Coldfire
Agere Starcore and 16K DSP with Agere tools

I think a lot of the Cell phones with ARM have combined ARM+DSP in a single
piece of silicon. Other phones may have UI handled with one processor, GSM,
etc. with another processor and voice algorithms with another processor.
Each processor may be from adifferent vendor, run a different scheduler and
use different tools...all within the same phone. So the tools and RTOS are
multiple.

Cell phones from all the big guys have a variety of Operating Systems, but I
think the main RTOS used are OSE, RTXC and Nucleus. So you could check out
what processors and tool chains those RTOSs are supported by.

Symbian apparently now has Real-Time extensions that allow it to do more
time-sensitive operations like reading the SIM card.
