FPGA在数字电视节目录制系统中的应用

The Application of FPGA in the Digital TV Record System

介绍了一种利用FPGA和ARM处理器实现的数字电视节目录制系统。重点论述了FPGA在系统中完成的功能:输入数据合法性检测、输入节目的解复用、输出节目的码率调整和时钟调整、总线仲裁及控制管理SRAM等。

In this paper, the realization of digital TV record system using FPGA and ARM is recommended. The functions of FPGA in the system are emphasized including checking the validity of the input data, adjusting the rate of output data, arbitrating for the ownership of system bus and controlling SRAM.
