摘要
介绍了基于USB总线的PCM帧同步及数据合并解调器的设计与实现,选用Cypress公司的CY7C68016A作为USB接口芯片和Altera公司的FPGA作为控制器完成硬件设计,并基于VHDL、C/C++语言完成软件设计。该设备主要用于PCM码流与USB总线的数据交换,已在遥测接收系统中用于PCM解调和数据处理。
The PCM demodulator of frame synchronization and data combination based on USB bus was designed and realized.As to hardware design,the CY7C68013A made by Cypress Co.and FPGA made by Altera Co.were respectively selected as USB interface chip and controller.For software design,the VHDL and C/C＋＋ language were used.The device is mainly used for data exchange between PCM data scream and USB bus.It has been used in telemetry receiving system for PCM demodulation and data processing.
