WebMar 16, 2024 · The AXI4 master issues burst read requests to the DDR3 controller via the interconnect. Burst length is 8, burst type is INCR and burst size is 4. My read data bus width is 128 bits. So when I place a read request starting from address 0x8000_0000, I get data in the form of 8 beats from location 0x8000_0000 to 0x8000_007F. So far all good.
