axi_bram_ctrl_0: Bram Controller,AXI接口的Bram控制器; blk_mem_gen_0: Block Ram 简单介绍下Block Design的AXI Interconnect IP核使用(因为Block Design可以实现自动连线,自动设置位宽等信息,所以设置内容没有AXI Interconnect RTL多,后者专用于Verilog代码中使用) 图2 这个
Kernel Interrupt Service Routine (ISR) – This part receives an interrupt request from the Interrupt Controller, serves the interrupt, and sends an acknowledge signal back to the Interrupt Controller, so that it can process the next IRQ. IPCore Driver (one per interrupt) – This part receives...
然后将Concat核的输出连接到AXI interrupt controller的intr[0:0]脚即可。
