Predictor miss decoder updating line predictor storing instruction fetch address and alignment information upon instruction decode termination condition

1. Field of the Invention A line predictor caches alignment information for instructions. In response to each fetch address, the line predictor provides information for the instruction beginning at the fetch address, as well as alignment information for up to one or more additional instructions subsequent to that instruction. The line predictor may include a memory having multiple entries, each entry storing up to a predefined maximum number of instruction pointers and a fetch address corresponding to the instruction identified by a first one of the instruction pointers. Since the line predictor provides alignment information from one entry per fetch, the line predictor may provide a flow control mechanism for the initial portion of the pipeline within a microprocessor. Each entry may store combinations of instructions which the hardware within the pipeline may handle without creating stalls resulting from the combinations.
