A controller comprising a pipeline including a plurality of connected sequential elements wherein a first sequential element is connected to one or more transaction sources; a flow control logic including at least one resource utilization value register; resource allocation logic responsive to a transaction valid signal and one or more adjustment inputs, and comparison logic having a threshold value and a transaction control signal output connected to the one or more transaction sources; pipeline control logic having an adjustment output connected to the resource allocation logic; and a resource control logic having an output connected to an adjustment input of the resource allocation logic.

An associative cache memory for a computer with improved cache hit times. All possible data items are presented to bus driver circuits, thereby deferring data selection as long as possible. Driving and multiplexing are combined. The output of tag comparison directly selects at most one set of driver circuits. As a result, the only processing time in series with tag comparison is driver circuit selection. Since the data selection delay in series with tag comparison delay is reduced, the time delay is reduced for a clock edge for data driving after tag comparison, thereby enabling a faster clock.
