摘要:
A method of arranging and operating a multiprocessor computer server system having "split-transaction bus" architecture, including bus modules operating with an address phase and a cycle phase, and arranged for access by a prescribed resource stage, to facilitate "RETRY", this method including; providing a Cache Tag and Address Compare, arranging the system so that a first bus module stores the address for the Resource stage in the Cycle Tag; and comparing subsequent address bus cycles to the contents of the Cache Tag so that, given a "match", a "RETRY" direction is responsively sent to any other bus module that requests access.
摘要:
Described are techniques to stabilize storage devices receiving signals from plural asynchronous docks, especially to avoid "metastability", in particular, a multi-dock pulse synchronizer circuit with an IN-section for receiving and storing prescribed impulses and input cock signals, and for responsively outputting intermediate signals: and an OUT-section for receiving and storing the intermediate pulses, synchronous with certain output clock signals and processing them to generate certain output-signals which avoid metastability.
