Hi, I am working on porting GSM Enhanced Full Rate (EFR) Speech codec on a customer DSP. Currently We are working on porting ACELP ( Code Book Search ) functions. I observed that the code book searh algorithm implemented in C code is complex and is very difficult to optimize in assembly because of complex address generation required. Algoithmic change in ACELP functions will reduce the complex address generation process and also will reduce the cycle count. If anybody worked on porting the EFR code on TI or any other DSP, Any inputs on changing the C algorithm or any pointers for the same. Regards, Nitin |
