When a thread is stalled by a cache miss, the processor pipeline checkpoints the register file, switches to runahead mode, and continues to issue instructions from the thread that is waiting for memory. The thread of execution in run-ahead mode is known as a ''scout thread''. When the data returns from memory, the processor restores the register file contents from the checkpoint, and switches back to normal execution mode. The computation during run-ahead mode is discarded by the processor; nevertheless, scouting provides speedup because memory level parallelism (MLP) is increased. The cache lines brought into the cache hierarchy are often used by the processor again when it switches back to normal mode. ==Rock processor scout== Sun's Rock processor (later canceled) used a form of hardware scout. However, any computations in run-ahead mode that do not depend on the cache miss may be retired immediately. This allows both prefetching and traditional instruction-level parallelism. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hardware scout」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
