how to transfer an INC type burst type transfer of 64 bit size on the 32 bit data bus width?
You will need some logic to change the width of the 64-bit transaction to suit the available 32-bit data bus. This downsizing logic will need to double the length of the INCR burst, possibly resulting in 2 INCR bursts if you are using AXI3.
Was there something specific about this downsizing requirement that was concerning you ?
thanks, i got the point
