Dear all, I want to know a few things about the optimization features in the CCS. 1) I am using the CCS 2.1 simulator .... does just setting the '-o3' optimization feature during building of the project give the best optimization ....? OR ....are there anymore options to choose to get a better level of optimization ? (without touching the C source code) 2) If somebody has experience in with ITU fixed-point C codes (of Speech codecs) .... how much efficient will a crosscompiled optimized version be than a pure assembly coded code .... in effect I want to know how efficient the optimization in CCS is ...? 3) I want to know whether most of the implementations of the ITU-T speech codecs on DSPs are done by optimizing the cross-compiled code rather than writing raw assembly code ..... ? What are the general methods of optimization adopted ...? It would be of great help to have some help on these queries ..? Thank you very much. regards, Sheetal
