MPEG-2解码芯片的AMBA总线和DMA控制器设计

Design of AMBA bus and DMA controller used for MPEG-2 decoder chip

MPEG-2是目前应用最广泛的数字音视频编码的国际标准,采用Top-Down的方法,完成了MPEG-2解码系统芯片中的AMBA(Advanced Microcontroller Bus Architecture)总线和DMA(Direct Memory Access)控制器的RTL级代码设计,并搭建测试平台进行功能仿真,最后通过了FPGA的验证。测试结果表明该设计能够在150MHz频率下工作,满足数字电视标清和高清的标准要求。

MPEG-2 is the most widely used international standard about digital audio and video nowadays.Using top-down methodology,AMBA system bus and DMA controller are implemented in Verilog HDL and the whole design is targeted to a FP-GA device for verification.The test results show that the design can operate at 150 MHz,which meets SDTV and HDTV standard.
