基于FPGA与ML7204的音频编解码设计

Speech CODEC Design Based on FPGA and ML7204

通信系统中的语音编解码多基于DSP来实现,采用相应的DSP硬件设计及软件算法,可以较方便地实现多路语音处理。而在某些小型的G.729格式的通信系统中,采用硬件编解码的模式,结合FPGA来协同设计,可以将语音编解码更为方便地应用在通信系统的终端设备中,大大减少了设备设计的复杂度。

Speech CODEC in voice communication system is usually processed by DSP.Designing DSP hardware circuitry and software arithmetic will solve speech of multi-channels more conveniently.However,in some G.729 format,low-cost information systems,a module of hardware CODEC cooperating with FPGA will realize Speech CODEC more easily in the communication terminal designing and reduce the complexity of embedded system engineering.
