| 摘要: |
| 基于DAM6416P图像处理开发平台和TDS560USB型DSPs实时仿真器,实现MPEG-2/MPEG-4视频流的实时转码。该转码系统的软件部分由PC主机端程序和DSPs端程序组成,采用两级缓冲区的形式输入/输出数据,DMA6416P图像处理平台以600MHz的TMS320C6416 DSPs为核心,提供256M字节的SDRAM,4M字节的FLASH、PCI接口等,实现了MPEG-2/MPEG-4视频流的转码。 |

| Abstract: |
| A method of MPEG-2/MPEG-4 video stream transcoding,based on DAM6416P image processing hardware platform and DSPs real-time simulator of the TDS560USB,is implemented in this paper.The video stream transcoding consists of main programs at PC and DSPs programs,and input/output data in the form of two-level buffer.The DAM6416P image processing hardware platform uses TDS560USB DSPs with 600MHz as the core,providing the SDRAM with 256M bytes,FLASH with 4M bytes,PCI interface,and accomplishing video stream transcoding between MPEG-2 and MPEG-4. |
