摘要：A distributed shared memory multiprocessor that includes a first processing element, a first memory which is a local memory of the first processing element, a second processing element connected to the first processing element via a bus, a second memory which is a local memory of the second processing element, a virtual shared memory region, where physical addresses of the first memory and the second memory are associated for one logical address in a logical address space of a shared memory having the first memory and the second memory, and an arbiter which suspends an access of the first processing element, if there is a write access request from the first processing element to the virtual shared memory region, according to a state of a write access request from the second processing element to the virtual shared memory region.
