Basic interrupt examples on CCSV4 Cortex-M3 simulator

Hi,

I am a "Hello World" kind of programmer in the area of Cortex M3 . I am trying to use Cortex-M3 simulator in CCS  for programming the NVIC and I have few questions. Please bear my ignorance regarding the interrupt knowledge

1. Is it possible to port directly the gcc(Code sourcery) examples for interrupts onto Cortex-M3 in the CCSV4 environment?I tried in vain porting the code onto the simulator.

2. Is there a basic example that explains how to program Cortex-M3 in particular the NVIC in the CCSV4 environment on a simulated Cortex-M3 platform?

3. Are there any good link where one can understand the programming examples for Cortex-M3 in the CCSV4 environment?

Thanks,
