Abstract
A microprocessor is shown, in which a branch predictor and an instruction cache are decoupled by a fetch-target queue (FTQ). The FTQ stores at least an instruction address whose branch prediction has been finished by the branch predictor. The instruction addresses queued in the FTQ is to be read out later as an instruction-fetching address for the instruction cache. The instruction address that is input into the branch predictor and used for branch prediction leads the instruction-fetching address.
