ABSTRACT:
A data processor asynchronous demand selector includes a time selector for selecting an asynchronous demand according to the time it is applied to the selector. A spatial selector controls each demand selected by the time selector according to a predetermined, arbitrary criterion. A temporary clock responds to the time selector to derive synchronization signals which are applied to the time and spatial selectors. The temporary clock also supplies synchronization signals having occurrence times determined by the time of the selected demand to a common resource member for the various units of the system, e.g., a data memory that is selectively refreshed, or has data written into or read from it.
