DMA-330(二) DMA内部的block diagram: DMAC包含一个instruction processing block,来process program code,control DMA transfer. program code一般放在一个system memory中,DMA通过AXI接口来访问. DMA内部有一个cache来临时保存instructions,cache的length和depth可配. 该IP DMAC内部可配8个DMA channel,每个channel都支持...
As the below diagram shows, the PIT is as the hardware trigger of the ADC_ETC, when it happens, the ADC_ETC will complete 8 conversions due to the chain feature, when the conversion completes, a DMA request will arise and be assigned to a DMA channel to transfer the ADC data to ...
When that transfer completes, a second transaction reads the data back along the same path, as shown in Figure 15. MSC8103 Core MSC8103 M1 RAM MSC8103 System Bus MSC8122 Local Bus DMA FIFO MSC8103 DSI M1 Core 0 M1 Core 1 M1 Core 2 M1 Core 3 Figure 15. DSI Transaction Diagram The ...

传输层次结构——传输最多分为四个级别:DMA传输级别、块传输级别、传输级别和AXI传输级别(DMA transfer level, block transfer level, transaction level, and AXI transfer level)。这样做是为了最小化下面几种情况的影响,即通道被授予一组特定的外设,但外设没有足够的数据持续传输,但是在这种情况下,通道也不能提供...
CONSTITUTION:A circuit shown in the diagram is provided to a control circuit within a DMA controller. The contents of a transfer count register TCR are set at 0 when the DMA controller is carrying out the DMA transfer in response to the DMA request signal given from an input/output ...

dma_module.wait_transfer_complete() 1. 处理DMA传输结果 一旦DMA传输完成,我们可能需要处理传输的结果。这可以是验证传输的数据、处理传输的结果等。在这里,我们使用了dma_module.process_result()函数来处理DMA传输的结果,并将结果保存在result变量中。
