| 摘 要： | TMS320VC5410提供3个高速、双向、多通道带缓冲串口McBSP,它可以与C5410其它器件、编码器或其它串口器件通讯.直接内存访问(DMA)可以在内存和McBSP之间实现数据传输,而且不需要CPU的干预,它可以在片内存储器、片内外设和片外设备之间以后台运行方式传输数据,DMA有6个可编程的信道,可独立实现读写操作.

| Abstract: | TMS320VC5410 digital signal processor provides multiple high-speed, full-duplex, multi-channel buffered serial ports (McBSP), it can directly communicate with C5410 devices, coders and other serial interface in a system. It can directly access memory (DAM), can transfer data between memory and the McBSPs without intervention by the CPU. It can communicate data among internal memory, internal peripherals and external devices in background operation mode of CPU. DMA has six independent programmable channels, and it can independency realize read-write operation. |
