Abstract
A microprocessor with a solution to instruction fetching failure is shown. The branch predictor and the instruction cache are decoupled by a fetch target queue. In response to instruction fetching failure of a target fetching address, the instruction cache regains the target fetching address from the fetch target queue to restart the failed instruction fetching.
