ABSTRACT:
A processor is disclosed comprising a front end circuit that fetches a series of instructions according to a program sequence determined by at least one branch prediction, a register renaming circuit that allocates execution resources to each instruction, and an execution circuit that executes each instruction in the instruction stream. The execution circuit causes the front end circuit to refetch the series of instructions if a branch misprediction is detected. A stall signal disables the register renaming circuit until the execution circuit commits the branch result to an architectural state according to the program sequence.
