摘要： A method for speculative execution of instructions, the method includes: decoding a compare instruction; speculatively executing, in a continuous manner, conditional instructions that are conditioned by a condition that is related to a resolution of the compare instruction and are decoded during a speculation window that starts at the decoding of the compare instruction and ends when the compare instruction is resolved; and stalling an execution of a non-conditional instruction that is dependent upon an outcome of at least one of the conditional instructions, until the speculation window ends.

摘要： A method for managing a hardware instruction loop, the method includes: (i) detecting, by a branch prediction unit, an instruction loop; wherein a size of the instruction loop exceeds a size of a storage space allocated in a fetch unit for storing fetched instructions; (ii) requesting from the fetch unit to fetch instructions of the instruction loop that follow the first instructions of the instruction loop; and (iii) selecting, during iterations of the instruction loop, whether to provide to a dispatch unit one of the first instructions of the instruction loop or another instruction that is fetched by the fetch unit; wherein the first instructions of the instruction loop are stored at the dispatch unit.
