RMW operation on SRAM via AXI

niket

I am implementing Read Modified Write on SRAM through AXI. What is the role of awsize and wstrbe?

Say data width is 64 bits, and awsize is set to support 64-bits, but the underlying wstrbe are only valid for lower 32-bits (8'b0000_1111). Does this candid for RMW operation? Or, it solely should depend on awsize and supported data widths?

 

Thanks.
