关于DSP的EDNA使用寄存器和相关API函数的总结资料，EDMA是在DMA上发展起来的一种传输方式，它拥有DMA传输的全部特性，除了具有DMA后台操作（即不占用CPU的时钟），高吞吐率等特点外，EDMA比DMA通道的功能

更加强大-EDNA on the use of registers and DSP-API functions related to the summary information, EDMA is developed on a DMA transfer method, it has all the characteristics of DMA transfers, in addition to DMA background operation (ie, do not take up CPU clock), high throughput characteristics outside, EDMA DMA channel than the more powerful
