Method and system to preprogram and predict a next microcode address

摘要

A microprocessor includes a first memory to store microcode and a second memory to store predicted micro-operation addresses. Micro-operation addresses are predicted, stored in memory, and retrieved to get the next micro-operations from the microcode memory. Misprediction recovery logic is used to determine if the next predicted address is correct and to determine a recovery address to correct the predicted address if the predicted address is incorrect.
