    • In a multiprocessor system, each processor module comprises a processor, a distributed shared memory, a distributed memory coupler for controlling copying between distributed shared memories and a distributed memory protector for protecting said distributed shared memory against illegal access. The distributed shared memories are assigned global addresses common to all the processor modules, and the distributed shared memory of each processor module has its addresses shared with the distributed shared memory of each processor module which is the destinatiion of data transfer. Message buffers and message control areas on the distributed shared memory are divided into areas specified by a combination of sending and receiving processor modules. A processing request area on the distributed shared memory is divided corresponding to each receiving processor module and arranged accordingly. The processing request area on the receiver's side distributed shared memory has a FIFO structure. The sender's side distributed memory coupler stores identifying information of the destination processor module between the processor module communication and, upon occurrence of a write into the distributed shared memory, sends a write address and write data to the destination processor module. The receiver's side distributed memory coupler copies the received write data into the distributed shared memory of the processor module to which the distributed shared memory coupler belongs, by receiving write address and write data from the sender's side distributed memory coupler.
    • 在多处理器系统中,每个处理器模块包括处理器,分布式共享存储器,用于控制分布式共享存储器之间复制的分布式存储器耦合器和用于保护所述分布式共享存储器以防止非法访问的分布式存储器保护器。 分配的共享存储器被分配给所有处理器模块通用的全局地址,并且每个处理器模块的分布式共享存储器具有与作为数据传输命名的每个处理器模块的分布式共享存储器共享的地址。 分布式共享存储器上的消息缓冲区和消息控制区域分为由发送和接收处理器模块组合指定的区域。 分配的共享存储器上的处理请求区域对应于每个接收处理器模块分配并相应地布置。 接收机侧分布式共享存储器的处理请求区域具有FIFO结构。 发送方侧分布式存储器耦合器存储处理器模块通信之间的目标处理器模块的识别信息,并且在发布到分布式共享存储器中时,向目的地处理器模块发送写入地址和写入数据。 接收机侧分布式存储器耦合器通过从发送器侧分布式存储器耦合器接收写入地址和写入数据,将接收到的写入数据复制到分布式共享存储器耦合器所属的处理器模块的分布式共享存储器中。
