Abstract
A computer-implemented method for predicting a taken branch that ends an instruction stream in a pipelined high frequency microprocessor includes receiving, by a processor, a first instruction within a first instruction stream, the first instruction including a first instruction address. The computer-implemented method further includes searching, by the processor, a stream-based index accelerator predictor one time for the stream; determining, by the processor, a prediction for a branch ending the branch stream; influencing, by the processor, a metadata prediction engine based on the prediction; and updating, by the processor, a stream-based index accelerator predictor with information indicative of the prediction.
