| 释义 | daisy chaining 菊花式链接(法);［雏菊链］ A time-shared bus system consisting of a single bus requestline onto which all processors are tapped in parallel. A bus grant line runs serially through all theprocessors. When the arbiter sees a bus request come in, it sends its reply on the bus grant line. Non-requesting processors ignore the bus and let the grant signal pass while the requesting processor locks the signal until the service is over. 由单一请求总线构成分时总线系统的方法,所有处理机均并行地与总线相联。总线应答 线串行通过所有处理机。当仲裁器发现有总线请求进入时,就在总线应答线上发送应答信号。未提请求的处理机放弃总线,并将应答信号传至下一级,而提出请求的处理机则将此信号 锁定进行服务,直至服务结束。 |
