Abstract
Redundant acknowledgment between agents performing a loopback test over bidirectional communications bus is described. In one example, in a processor including a communications agent coupled to a bidirectional communications bus, the communications agent initiates loopback communications to a second agent, sends a packet including a redundant acknowledgment sequence to the second agent, receives the packet including the redundant acknowledgement sequence looped back from the second agent, determines whether the received redundant acknowledgment sequence is valid, sends a test sequence to the second agent, receives the test sequence looped back, and if the received redundant acknowledgment sequence is determined to be valid, then checks the received test sequence.
