WebThe AXI4-Lite slaves have been implemented with SystemVerilog as two dummy modules. It is my intention for slave0 to have 8 x 32bit memory, from 0x84000_0000 (base address) to 0x84000_001c. Slave1 would also have 8 x 32bit memory, from 0x84000_f000 (base address) to 0x84000_f01c. WebWe would like to show you a description here but the site won’t allow us.
