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. Platform: |
