Branch predicting apparatus and branch predicting method
Abstract:
A return address in response to a return instruction corresponding to a call instruction is stored in a return address stack when a branch history detects presence of the call instruction. When the branch history detects the presence of the return instruction before a branch reservation station completes executing the call instruction, the return address in response to the return instruction is not stored in the return address stack. If so, an output selection circuit predicts a correct return target using information stored in the return address stack.
