question about hwi - jogg...@gmail.com - Jul 11 8:46:45 2009

Hi,all
    I am working on application on C64x+, but not familiar with
DSP/BIOS. Currently TI provides many things that used to be
done by firmware engineers. PSP(Platform support platform) is one 
of such things. I am not a firmware engineer, so I have some question
about PSP. PSP contains peripheral drivers, but in the tcf file
the peripherals don't have corresponding HWI object. In my view,
each peripheral should have a corresponding HWI object.

Thanks 
Best Regards
Jogging

HWI describes an interrupt.  A driver may or may not use an interrupt.  A
peripheral may or may not use a driver.

I don't see any rule in any OS (Linux, WinXP, DSP/BIOS, etc) that requires a
peripheral to use an interrupt.
