DSP data corruption - sandeepspm - Nov 6 5:53:56 2006



Hi all, 
      I am using C55x functional simulator.I am experiencing some
weird data corruption while passing parameters to functions.The data
is getting corrupted in some unknown way and in the end i am getting
entirely different values at the called function.

Is it the problem with the simulator? or is it the program ?.can
anyone  comment on this.

Thanks in Advance 

Sandeep

hi,
  there will be no problem with the Functional simulator. 
where from u r calling ur asm function , has to be checked first.
  if u r calling it from C , check whether Stack and Heap sizes are sufficient.and then try to
increase their sizes.
  if it is from another Assembly file, check whether u r following the "calling
conventions" correctly.

  regards,
