daisy chain bus 菊花链[菊链形]总线;[雏菊链汇流排] A bus on which signals are transmitted in serial fashion.Each unit on the bus can modify the signal before passing it on the next device. This approach is used mainlyfor signals related to interrupts or polling circuits. Whenever a device requires service, it blocks the signal. So the devices that are closest to thecentral processor usually have the first chance to request service. 以串行方式传送信号的一种总线。在这种总线上,各个设备在把信号(主要是与中断或轮 询电路有关的信号)传递给下一个设备之前,可以修改该信号。一旦某个设备需要服务时,它 就截住这个信号,这样,与中央处理机最接近的设备可优先获得服务机会。 |
