I observed that every transaction on the AHB Bus Matrix encounters an initial !HREADY - even in the absence of any other master/contention.
I chased it down to the output stage arbiter. I tried both round-robin and fixed arbitration schemes.
Is this to be expected? Is there any way to avoid the initial arbitration delay on uncontested ports?
Colin,
Thank you for the always knowledgeable response.
Does the same hold for nic400? I am observing a point-to-point connection in the absence of any other traffic experiencing delays when no such delays occur when nic400 is not in the path. Is there a hi perf nic400 option?
Thanks again, Tom
