Dear Experts, I am working on the development of a software codec for the TMS320C6416 DSP from TI. I am using the Test and Evaluation Board with XDS510PP and Code Composer Studio Version 2.10. I am at a stage where my code is written in C only and I have used C instrinsics for max and min only. I profiled the code with "Profiler" Option in CCS as well as using the C6xxxx simulator (with load6x -g test.out). I find that the count of the cycles (Excl., Incl., Excl. Max., etc) are different in the two cases! I am confused as to use which one to use for further optimization of the code. I prefer using the load6x as it is faster to run than the profiler (And I donot know the reason why!) but I am worried that I am getting some garbage data. Could anyone share any thoughts on this? I badly need help on this. Another question. Does the "Excl. Total" include the cycle that the processor required for memory access (for both the profiler in CCS and the load6x)? In my code, I am not using any CSL/PSl function and no DMA as well. Thanks in advance for your help, Indrajit |
