Vulcan's front-end is tasked with fetching instructions from a ready thread instruction stream and feeding them into the decode in order to be delivered to the execution units. Since Vulcan supports up to four threads, a thread scheduler determines from which thread's instruction stream to operate on. This determination is done on each cycle with the help of the branch predictor with no added cost. | Vulcan's front-end is tasked with fetching instructions from a ready thread instruction stream and feeding them into the decode in order to be delivered to the execution units.
