sharedexecutive system 共享执行系统 A tightly coupled system in which several CPUs share a single memory. It uses a single shared operating system executive to control the execution of tasks. Thus, provisions f or synchronization,interlocking, and interprocessor communication must be made in the hardware to a ccommodate a true multiprocessor operating system. The major difference between configurations is the method of accessing the memory. 一种紧耦合系统,其中多个CPU共享一个存储器,它使用一个共享的操作系统执行程序,以控制各任务的执行。因此,用于同步、互锁及处理机间通信的措施必须 用硬件实现,以适应真正的多处理机操作系统。配置之间的主要差异是访问存储器的方法不 同。 |
