Question about AXI transfer

Jump to solution

I 'm working with the AXI Master IP and need to replace one 32 bit transaction by 4 separate 8 bits transaction ( ADDR, ADDR+1, ADDR+2, ADDR+3) using only lower 8 bits from Data Bus.
Question is what AXI signals determine the transfer has to be done byte by byte over lower 8-bit data bus?

Hi @olkhramus,

You can use the strobe signal WSTRB to specify which byte(s) is valid within the transaction.
Please check AXI4 Protocol Specification document for further details about this signal.
