Description: DM642上的DMA性能一个简单的介绍和分析。
DM642中的DMA称为EDMA（Enhanced Direct Memory Access）,其EDMA控制器支持64个相互独立的DMA通道，每个通道都可以接受系统外设事件的触发或者CPU的指令的触发，不同DMA传输之间还可以进行连接，构成各种复杂的DMA操作，在600MHz主频时可以提供2.4GB/秒的数据吞吐量。具备的1维、2维传输模式，非常适合图像的处理。

-DMA performance on the DM642 a brief introduction and analysis. DM642 The DMA called EDMA (Enhanced Direct Memory Access), the EDMA controller to support 64 independent DMA channels, each channel would be acceptable to all system peripherals, or trigger events trigger CPU instructions, different DMA transmission of can also be used for inter-connections, constitute a complex DMA operation, in the 600MHz frequency can provide 2.4GB/s data throughput. With the 1-dimensional, 2-dimensional transport model, very suitable for image processing.

Description: DMA是DSP应用中的一大特色，把内核的大量资源用于运算，想做得朋友看看
这是DM642使用BIOS和CSL LIB 作EDMA简单例子. 在CCS BIOS 中需要作 中断--EDMA--edmaHwi 的设置. Spru234 和 spra636a 都是有用的参考
解释见注释.-DMA is a DSP applications, a major feature of a large number of resources to core operations, you want to go to friends to see if it is DM642 using BIOS and CSL LIB for EDMA simple example. In the CCS BIOS needs to be interrupted- EDMA--edmaHwi settings. Spru234 and spra636a are useful reference for interpretation, see note.
