Introduction to the Advanced Extensible Interface (AXI)

WitrynaI am using AXI interconnect IP v2.1 which connects 64-bit master (ZynqMP\+) with 2x64-bit and 1x32-bit slaves. The advanced configuration of the IP is disabled, so the AXI crossbar uses 32-bit data width. When ZynqMP\+ performs 64-bit access, e.g. of address 0x80003000, the interconnect splits it to two accesses 0x80003000 and 0x80003004 … Witryna23 wrz 2024 · A narrow access is one where AxSIZE is narrower than the data width of the AXI interface.
