DMAC用来实现DMA传送的控制器,在DMA期间控制系统总线,需要CPU对其进行初始化编程设置 flow controller determine thelengthof a DMA block transfer andterminatesit. either the DW_ahb_dmac, or source/destination peripheral can be flow control, 如果在channel enable前知道传输的block size, DW_ahb_dmac需要被设...
The AHB DMA Controller (DW_ahb_dmac) can be used in an AHB subsystem to perform DMA transfers between AHB peripherals. When the AHB subsystem is bridged to an AXI subsystem through a combination of DW_ahb_eh2h and DW_axi_hmx, it is possible to do DMA transfers between AHB and AXI pe...
