标准摘要
[中文适用范围]: 该国际标准规定了STbus的逻辑规范,STbus是一种高性能、高可靠性的系统总线。 STbus 采用高速时钟的同步传输方法和分割传输方法,能够最大限度地减少一个总线操作期间的总线保持时间并有效地使用总线。 本规范给出的内容如下: a) 系统总线接口信号规定; b) 总线操作和每个总线操作的传输协议; c)回写高速缓存一致性控制,用于维持多处理器系统中的共享存储器和每个处理器的高速缓冲存储器之间的一致性; d) 使用奇偶校验和控制信号双工配置的故障检测功能。 [外文原描述]: This International Standard specifies the logical specifications of STbus which is a high-performance and highly reliable system bus. STbus adopts a synchronous transfer method with a high-speed clock and a split transfer method enabling to minimize bus holding time during one bus operation and to use a bus efficiently. This International Standard is applicable to a high-performance system bus or an I/O bus in a multiprocessor system. Typical STbus applications are a system bus and an I/O bus in a tightly coupled multiprocessor system, and a system bus in a loosely coupled multiprocessor system.
