Abstract: A multiprocessor device includes cores and at least one ingress-write ordering circuitry (IWOC) including first and second counters associated with first and second destinations. The IWOC is configured to assign sequential numbers to write transactions received from a source, according to an order of reception at the IWOC, and to forward the write transactions from the IWOC to the first and second write-transaction destinations, while preserving the order, by incrementing the first and second counters such that both the first counter and the second counter track a sequential number of a next write transaction that the IWOC will forward, forwarding a first write transaction to the first destination only provided that the sequential number of the first write transaction matches the first counter, and forwarding a second write transaction to the second destination only provided that the sequential number of the second write transaction matches the second counter.
