초록

In this paper, we implement a 2.4 kbps STC speech codec using the TMS320C6201 DSP The main job for this work is twofold: one is to convert floating-point operation in the codec into fixed-point operation while maintaining the high resolution, and the other is to optimize the program to make it run in real time with memory size as small as possible. The implemented decoder uses 54.8 kbyte of program memory, 29.7 kbyte of data ROM and 55.2 kbyte of data RAM, respectively. It also uses about 45% of maximum computation capacity of TMS320C6201.
