摘要:Data transmission for writing data into a shared memory is performed by a high-speed dedicated line provided between each processor and the shared memory. When aprocessor performs writing to a shared memory space, the processor notifies an update
notification bus corresponding to the conventional global bus, to which address theupdate is to be performed. The other processors which have detected this notificationinhibit access to that address and wait for the write data to be sent to the address via thededicated line. When the data has arrived, the data is written into the correspondingaddress. Here, the data is also written into the corresponding address, therebymaintaining the cache coherency. Moreover, when transmitting a write address, it isnecessary to acquire the bus use right while data transmission is performed by using thededicated line, which significantly reduces the time required for acquiring the bus useright.
