Patent number: 7383455Abstract: A method and apparatus are disclosed for transferring multi-source/multi-sink control signals using a differential signaling technique. An “active” state is transferred on a multi-source/multi-sink control signal network by inverting the previous voltage level, and an “inactive state” is transferred by maintaining the previous level. A change in the voltage level associated with a given control signal indicates that at least one node on an SoC device is asserting the corresponding control signal. In order to detect a change in the signal state from a previous cycle, each node includes a memory element, such as a latch, for maintaining the previous state. In this manner, a voltage level from the next interval can be compared to the recorded state to detect a change of state indicating an assertion of the control signal by another node.Type: GrantFiled: January 8, 2007Date of Patent: June 3, 2008Assignee: Agere Systems Inc.Inventors: John Susantha Fernando, Hyun Lee, Trevor Edward Little
