摘要
由于图像处理中数据量非常大 ,数据传输往往成为实时图像处理的主要瓶颈 .TMS3 2 0 C64xx的 PDT传输为共享同一数据总线的外部设备和外部存储器之间传输大数量的数据 ,提供了一种高效的方式 .利用 PDT传输可以缓解数据传输的压力 .文中探讨了以 TMS3 2 0 C64xx为核心的视频图像实时处理系统中 ,基于 PDT传输的数据存储器接口设计 ,以 TMS3 2 0 C641 1为例设计了实际接口电路 ,并对附加控制逻辑进行了功能仿真 .
Because of the large quantum of data in image processing, data transfer is one of main bottlenecks. TMS320C64xx supports the PDT transfer, which provides an efficient way to transfer large amounts of data between an external peripheral device and an external memory device that share the same data pins. Using PDT transfer can lighten the stress of data transfer. In this paper the design of data memory interface based on PDT transfer in video image real-time processing system centered TMS320C64xx are discussed. An actual interface circuit is designed taking example for TMS320C6411, and the append control logic is functionally simulated.
