DMA传输中,分为block为传输,对应的就是Block Transfer level,DMA Transaction Level的Burst Transaction指的是外设配置的channel CTL寄存器中的msize,会根据msize的设置进行burst/signal传输;AMBA Transfer Level相当于AXI总线传输层次上面的,这个跟arlen/awlen的设置相关。如果想自己设置可通过channel CTL寄存器中的awlen/...
c. DW_axi_dmac 检查 CHx_CTL_ShadowReg.ShadowReg_Or_LLI_Valid 位,如果它被视为'1,' DW_axi_dmac 将影子寄存器内容复制到用于执行 DMA 块传输的寄存器(CHx_SAR 和/或 CHx_DAR、CHx_BLOCK_TS 和 CHx_CTL 寄存器),并将 CHx_CTL 和 CHx_CTL_ShadowReg 寄存器中的 ShadowReg_Or_LLI_Valid 位清除为 ...
DMAX_MSTIF_MODE为AXI版本选择 AXI参数配置 DMAX_SLVIF_MODE配置模式选择参数 DMAX_SAFETY_FEATURE_EN ECC校验功能。 低功耗相关参数配置 #感悟 因为整个DMAC的功能比较全,所以其面积也不小,因此在配置时,注意结合自己需求来配置,比如假如配置接口和主时钟本来就是同步的,那就没必要配成异步,否者会在同步处理上耗...

Using DW_ahb_dmac in an AXI Subsystem Introduction 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 ...
