新型高速DVB-ASI接口的设计与实现

Design and Implementation of a New High-Speed DVB-ASI

介绍了一种新型的ASI接口的设计与实现。以Cypress公司的CY7B933为基础,辅之以CPLD和FIFO,实现了ASI信号与TI的TMS320C6416的接口设计。该接口符合DVB-ASI的接口规范,可实现270Mbps的MPEG-2传输流传输。以文中实现的DVB-ASI接口为重点,详细阐述了其软、硬件组成与实现;最后,给出了DVB-ASI的测试实验。

A new highspeed asynchronous serial interface (ASI) is designed and implemented in the paper Based on CY7B933 of Cypress, and combined with CPLD and FIFO, the design realizes the delivery of MPEG2 transport stream from the ASI to TI's TMS320C6416 With emphasis on the realization of DVBASI, the architecture of both software and hardware of the circuit, as well as their implementation, is illustrated in detail 
