Abstract
The present invention is a method and apparatus to inject an external event to a first pipeline stage in a pipeline chain. A target instruction address corresponding to an instruction is specified. The external event is asserted when there is a match between the target instruction address and a pipeline instruction pointer corresponding to a second pipeline stage. The second pipeline stage is earlier than the first pipeline stage in the pipeline chain. The external event is unmasked via a delivery path between a signal representing the asserted external event and the first pipeline stage.
