An important attribute of the NoC is that the NMU includes a 2 KB read reorder buffer and each read transaction is tagged with a unique tag. This allows the transactions to be execute and return out of order, improving performance in various ways.
One of those ways is avoiding the SSID effect seen previously. However, the same does not apply to write transactions. The NoC NMU does not tag or reorder writes, and the SSID rule is applied. MC interleaving involves sending transactions to two or four slaves concurrently. This means SSID can become a factor limiting write performance if transactions share the same ID or a limited number of IDs.
