AT91RM9200 and RTEMS

[Ole Hansen]

Hello rtems-users

We are going to use RTEMS and Atmel AT91RM9200 and wondered:

The ARM920T - core used in AT91RM9200 seems to have 2 instruction-sets.

1. ARM High-performance 32-bit Instruction set
2. Thumb High Code Density 16-bit Instruction Set

Which one is used to build RTEMS/compile application for RTEMS ?????

Anybody know the performance difference running from 32-bit SDRAM or 16-bit SRAM ???

 best regards
