Memory read requests passing memory writes

摘要

Memory read and write requests are received. The read is received in accordance with a communication protocol that has a transaction ordering rule in which a memory read cannot pass a memory write. The memory read and write requests are forwarded to the first device in accordance with another communication protocol that has a transaction ordering rule in which a memory read may pass a memory write. The forwarded memory read request is allowed to pass the forwarded memory write request whenever a relaxed ordering flag in the received read request is asserted. Other embodiments are also described and claimed.
