Abstract: An audio recording and playing system is designed basing on the first 8M-bits Phase Change Test Memory manufactured successfully in China.The system is mainly composed of 8Mb PCM,Field Programmable Gate Array（FPGA）,audio input/output circuit and audio A/D_D/A conversion circuit（AD73311 chip） etc.Using FPGA as the main process unit,the system converts the audio input analog signals into digital signals and then stores the signals into the PCM when recording.And in the playing process,the system reads out the information stored in the PCM and then converts the audio digital signals to analog signals for playing.The results of onboard verification indicate that the effect of the system on storing and playing is good.Meanwhile,the system can conduct reading and writing operation on 8Mb PCM correctly and repeatedly.It is confirmed that the performance of 8Mb PCM is integral and reliable,which lays a solid foundation for the subsequent commercialization application of Phase Change Memory.
