摘　　要：为了简化数字卫星码流转发器的设计和降低其物理成本,提出了一种基于FPGA实现同步传输流转化为异步串行流的设计方案。首先介绍了异步串行口和8 B/10 B编码的原理,接着详细地阐述了系统的设计思想,功能模块的划分以及各个模块的具体实现,并给出了部分仿真结果,最后给出了系统的测试结果,达到了预期的设计目的。In order to simplify the satellite digital TV code stream transmitterPs design and descend its cost,a system design based on FPGA is proposed. Firstly the principle of asynchronous serial interface and 8B/10B encoding are introduced, then the designing ideal of system, the division of functional module,and each module＇s implement are described in detail,and part of simulated results is exhibited. Finally,the test result of system is presented,which meets the design goal so well.
