应用TMS320C542和FPGA组成数字电话留言系统

A Digital Telephone Meassage System with TMS320C542 and FPGA

介绍了采用 DSP和 FPGA实现数字电话留言系统的一种方案。通过对语音信号压缩编码实现高效数字录音及回放 ,用 TMS32 0 C5 4 2实现 G.72 9CS- CEL P压缩编码 ,用 XC4 0 0 5 E实现控制及地址译码等辅助功能 ,对DSP实现 CEL P编解码以及 FPGA实现控制器过程中遇到的问题进行分析并提出解决办法。

In this paper,a system scheme of the digital telephone meassage system with DSP and FPGA is introduced,which concerns the recording and replaying of compressed code pronounciations,compressive coding of G.729CS-CELP with TMS320C542,and system controling and address decoding with XC4005E. The problems analysis and solutions are also given.
