WebMay 1, 2024 · AXI4 protocol defines three burst types: Fixed (00), INCR(01) and WRAP(10). In FIXED mode, the address is the same for every transfer of burst—used for loading and emptying FIFOs for example. Length of burst varies from 1 to 16 transfers. In INCR, the subordinate increments the address and the length varies from 1 to 256 for AXI4. WebBurst Length: This is defined by the S_AXI_AWLEN and S_AXI_ARLEN signals. It provides the exact number of transfers in a burst. 1-256 (0x00 – 0xFF) for the INCR burst type. For all the other burst types, only 1-16 are supported.
