MPF ROB Reorder Buffer

MPF Reorder Buffer

By default, CCI-P read responses are unordered. A reorder buffer to sort read responses is added when the MPF parameter SORT_READ_RESPONSES is set.

The MPF ROB sorts all read responses so that they are forwarded to the AFU in request order. This sorting necessarily increases latency, especially on multi-channel platforms with asymmetric channels. The latency of a sorted multiplexed channel is at least the latency of the channel with the highest latency.
