The CS-ACELP program on a fixed-point DSP (Digital Signal Processor) chip and the codec system with this chip were developed for the quality tests of the ITU (International Telecommunication Union) standardization. Using the DSP chip, a codec board for personal computers was also implemented to support the development of CS-ACELP application systems. The CS-ACELP algorithm, which is approved as a Speech Coding Draft Recommendation G.729 in ITU, is expected to be used in the world-wide applications of personal wireless communication systems or PHS (personal handy-phone system) , time division multiplexing systems, and digital simultaneous voice and data communications.
