Abstract
A method and apparatus are provided for communicating translation command information in a multithreaded environment in a computer system. The computer system includes a processor unit, an instruction unit coupled to the processor unit, a cache coupled to the processor unit, a main memory, and a storage control unit including a dataflow control partition, a cache control partition, a translation control partition. A translation miss signal is sent from the dataflow control partition to the translation control partition, responsive to detecting a translation miss condition. A translation command next signal is sent from the translation control partition to the cache control partition responsive to the translation miss signal. Then a translation command signal is sent from the translation control partition to the cache control partition. Responsive to the translation miss signal, a steal command signal is applied to the instruction unit for providing the translation command priority over execution of another thread. A series of the translation command signals are sent from the translation control partition to the cache control partition, and in one control cycle, the translation cont…
