多處理器的使用可以從兩方面提高系統(tǒng)性能.首先,它減少了在執(zhí)行多個任務(wù)時模擬并發(fā)的需要. 其次,他可以使應(yīng)用程序運行得更快,當(dāng)然,這必須要求程序是以多線程方式來書寫的,這些線程可以并行地高效執(zhí)行.
Use multiple processors can improve system performance at two ways. First, it reduced the need of perform multiple tasks simulate concurrency. Second, it can let program run faster, sure, it required program use multip threads write, that can efficient execute parallel.
指令集并行:現(xiàn)代處理器可以同時執(zhí)行多條指令.
instruction-Level Parallelism:modern processors can execute multiple instructions at on time.
