overlaying modules at runtime | Freescale DSPs

Technical discussions about Freescale (Motorola) DSPs (including the DSP56000, DSP56300, DSP56600, 56800 DSPs).

Hi all, I have run in to memory problem (internal data memory (x- and
y-) as well as p-mem), I have flash memory space that I can use. My
application is monolithic in terms of program memory, I thought I
would separate out functional blocks and overlay p-mem, and bring in
functional blocks program memory from flash to p-mem. I am not sure if
this can be done. If it can be done can anyone point me to
documentations and/or example implementations? Motorola DSP56311

Take a look at the assembler and linker reference manuals:

http://www.freescale.com/files/dsp/doc/ref_manual/DSPASMRM.pdf
http://www.freescale.com/files/dsp/doc/ref_manual/DSPLNKRRM.pdf

There are some notes, particularly in the assembler manual 
that relate to load vs run time differences.

david
