基于FPGA的PCM码收发模块设计

Design of PCM Transceiver Module Based on FPGA

为检验采集模块输出的PCM码,设计基于FPGA的PCM码收发模块,通过设计模拟PCM码源、PCM码解码接收模块,自行判断输出和接收的正确性,收发模块逻辑功能由FPGA完成。解码接收后的数据经USB接口回传至上位机,通过上位机软件检验PCM码收发模块工作情况。

In order to test PCM signal output from the acquisition module, a PCM transceiver module based on FPGA is designed. The design of PCM simulation signal source and PCM decoding receiver module is to test the correctness of its output and reception. Transceiver module＇s logic function is completed by FPGA. Decoded data transfer to PC by USB interface and check PCM transceiver module working situation.
