Abstract
A method and apparatus are described for distributing multi-source/multi-sink control signals among nodes on a chip. Each node on the chip assists in returning the control signal to an inactive state at the start of each cycle. Thus, since all nodes contribute to returning the control signal to the inactive state, the control signal returns to the inactive state more quickly, near the start of a given cycle, and the remainder of the cycle remains available for a given node to drive the control signal. Each node includes an exemplary pulsed reset block that discharges the control signal network closest to it for a short interval, and over time the rest of the network, returning the network to an inactive state. Once the control signal network has been returned to an inactive state, the control signal may then be driven by a node during the remainder of the cycle.
