指令重试是一类EMON计数器。
通过最小化系统的致命失效概率,可得出在系统资源备份一定时的最佳指令重试时间。
By minimizing the fatal failure probability, the optimal instruction-retry time can be obtained under the condition that the resource backup is set.
通过知晓每循环的指令重试,系统就知晓了处理器内部正在执行的当前应用程序有多快。
By knowing instruction retired per cycle, the system knows how fast the current application is executing inside the processor.
