摘要
采用基于AMBE算法的专用语音压缩编/解码芯片,设计并实现一种基于FPGA的语音压缩编/解码系统.整个控制程序包括复位及时钟分频程序、发送端控制程序和接收端控制程序3个功能模块,控制程序的接收端和发送端都使用先进先出(FIFO)电路存储器.仿真结果表明,控制程序能够完成相应的功能,符合设计的目的和要求.
Adopting a special speech compression encoder/decoder chip based on AMBE algorithm,this paper designs and implements a FPGA-based speech compression encoding/decoding system.The whole control program include three function modules,those are reset and clock frequency,the transmitter and receiver control program.The receiver and transmitter of control procedures use the FIFO memory circuit.The simulation results show that,the control program can complete the corresponding function,and meet the purposes and requirements of design.
