Abstract
A method and apparatus are provided for detecting and handling an instruction flush in a microprocessor system. A flush mechanism is provided that is distributed across all of the execution units in a data processing system. The flush mechanism does not require a central collection point to re-distribute the flush signals to the execution units. Each unit generates a flush vector to all other execution units which is used to block register updates for the flushed instructions.
