Abstract
An apparatus including a protocol watcher adapted for use with a bus, a state machine adapted to detect known bug signatures on the bus, and a perturber adapted to intervene on the bus to prevent occurrence of bugs having those signatures. A system utilizing such includes a bus, a first agent coupled to the bus, a second agent coupled to the bus for communicating to the first agent according to a bus protocol, and the bus patcher coupled to the bus for monitoring a communication from the second agent to the first agent to identify an event which would cause an error in the apparatus, and for modifying the communication such that the event is avoided. Any of the protocol watcher, state machine, and/or perturber may be programmable.
