Abstract
A system and method for recovering from mispredicted paths in pipelined computer architectures. Targets within an instruction window exhibit spatial locality. To exploit this property, a mechanism detects the branch target within the instruction window. A second process eliminates the need for full renaming and re-execution of mispredicted paths by handling a dependency chain of instructions.
