ABSTRACT:
A method and apparatus for improved performance for handling priority agent bus requests when symmetric agent bus parking is enabled is disclosed. In one embodiment, a modified priority agent may be used. The modified priority agent may assert an unused symmetric agent bus request when it asserts its priority agent bus request. When a symmetric agent parks on the bus, continually asserting its symmetric agent bus request, the assertion of the otherwise unused symmetric agent bus request may cause the symmetric agent to withdraw its symmetric agent bus request. This may reduce bus response time for subsequent modified priority agent bus requests.
