摘要: 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150 MHz频率下工作,满足数字电视标清和高清的标准要求。

关键词: MPEG-2, AMBA总线, DMA控制器

Abstract: 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 FPGA device for verification.The test results show that the design can operate at 150 MHz,which meets SDTV and HDTV standard.

Key words: MPEG-2, Advanced Microcontroller Bus Architecture(AMBA) bus, Direct Memory Access(DMA) controller
