• AHB Lite Response

    Hi All,

                               I have doubt in ahb_lite hresp signaling when the address phase is extending.

    In the following diagram transfer address c is extending because of data phase of B.

    In 3rd clk cycle address C is sampled so that shall we expect the…

  • Relation between Hsel and Hready in AMBA AHB

    Hi,

    In my design I am having a scenario where my Hsel goes low during the data phase of a transfer and Hready goes high one cycle after that? (i.e hready high during address phase low during data phase and high again in the follwoing cycle 1->0 -> 1)…

  • AHB_LITE Extended address phase

    Hi All ,

                          The following figure shows the INCR4 burst transaction.

    What are the possible adjustment has to be made for this transaction…
