Abstract

A plurality of units which are coupled to transfer requests, transfer data over an asynchronous bus network during allocated bus transfer cycles. The network has a tie-breaking bus priority network which is distributed to a common interface portion of each of the plurality of units and grants bus cycles and resolves simultaneous requests on a priority basis. At least one unit includes bus saturation detection apparatus included within its common interface portion for monitoring bus activity over established intervals of time. The detection of the occurrence of at least one available cycle over the given interval of time signals that the bus network is not in a saturated state. When the indicator specifies that the bus network is saturated, the unit throttles down its operation by increasing the amount of time between issuing data requests. Throttling continues until the bus is no longer being saturated.
