Multichannel模式:在Scatter/Gather Mode下S2MM和MM2S都支持多个通道,Direct Register Mode不支持多通道,多通道相比非多通道,BD中增加了TID和TDEST,用来区分不同的通道。多通道支持2D-Transfer,从buffer address开始,读写HSIZE后跳过剩余的Stride – HSIZE个地址单元,下一次从buffer address + Stride位置开始,此过程迭...

The AXI Direct Memory Access (AXI DMA) IP core provides high-bandwidth direct memory access between the AXI4 and AXI4-Stream IP interfaces. Its optional scatter gather capabilities also offload data movement tasks from the CPU in processor-based systems. Initialization, status, and management regis...

是DMA:(Direct Memory Access),即直接存储器存取,是一种快速传送数据的机制。数据传递可以从适配卡到内存,从内存到适配卡或从一段内存到另一段内存。AXI4:主要面向高性能地址映射通信的需求;AXI4-Lite:是一个简单地吞吐量地址映射性通信总线;AXI4-Stream:面向高速流数据传输;AXI4总线分为主、从两端,两者间可以...
