I did the same thing, but the main reason why I am asking this is
because when I add this code I run out of program memory on my target
The platform I am porting to is the Motorola DSP56002 and it only has
512x24 bits of program ram and 2 256x24 bits data rams, all three
expandable to 64K
off-chip. And the operating speed is 20 MIPS. So I know that it really is not
suited for running Tremor at all, but I am doing this as a project in school.

I will try to add some notes there in a couple of weeks when I am
hopefully done with my port.
