Abstract: This application discloses a read/write operation execution method and a SoC chip. The read/write operation execution method includes: A first node receives a first message and a second message from a second node, where the first message is for requesting to perform a read/write operation on a first address managed by a third node, the second message is for requesting to perform a read/write operation on a second address managed by the third node, an execution sequence constraint of the read/write operation of the second node is stricter than an execution sequence constraint of the read/write operation of the third node; the first node obtains operation permission of the first address and operation permission of the second address from the third node; and the first node performs read/write operations on the first address and the second address.
