DMA中断代码如下：void DMA_RX_IRQHandler(void){ uint8_t tmp;if(DMA_GetITStatus(DMA_RX_Stream,...
DMA方式的特点为: 数据传送的基本单位是数据块。 数据是直接在设备─内存之间传送的。 仅在传送一个或多个数据块的开始和结束时才需要CPU对I/O的干预, 传送工作本身是由DMA控制器完成的。 2、DMA控制器的组成 (1)主机与DMA控制器的接口 数据寄存器(DR) 内存地址寄存器(MAR) 数据计数器(DC) 命令/状态寄存器...

4GB memory can be accessed in native DMA mode. ALL memory can be accessed if kernel module (KMD) is loaded. Execute kernel code on the target system. Spawn system shell [Windows]. Spawn any executable [Windows]. Load unsigned drivers [Windows]. ...
I am attempting to transfer memory from the PL to the PS, using AXI stream. At the moment, I have a counter that generates data and sends cyclic tlast signals into a FIFO, which is connected to a Xilinx DMA. I have a working asynchronous DMA driver that uses a kmalloc \+ dma_map_...
The PCI Express® DMA reference design using external memory highlights the performance of the Intel® Arria® V, Intel® Arria® 10, Cyclone® V and Stratix® V Hard IP for PCI Express using the Avalon® Memory-Mapped (Avalon-MM) interface. The design incl...
