变速处理器的特征在于两种执行速度：正常速度和降级速度。在正常情况下，它将以正常速度执行;在运行时可能会发生意外情况，导致它缓慢执行（但不会比降级速度慢）。自我监控的处理器会立即知道其速度是否在运行时福尔斯正常速度;相比之下，非监控处理器无法检测到运行时的性能下降。考虑了在一个不受监控的变速处理器上执行一个由一些较重要的组件和一些较不重要的组件组成的综合工作负载的问题。希望所有组件在正常情况下正确执行，而如果处理器以不低于其指定降级速度的任何速度运行，则更重要的组件应该正确执行（尽管不太重要的组件不需要）。
A varying-speed processor is characterized by two execution speeds: a normal speed and a degraded speed. Under normal circumstances it will execute at its normal speed; unexpected conditions may occur during run-time that cause it to execute slowly (but no slower than at its degraded speed). A processor that is self-monitoring immediately knows if its speed falls below its normal speed during run-time; by contrast, a non-monitored processor cannot detect such degradation in performance during run-time. The problem of executing an integrated workload, consisting of some more important components and some less important ones, upon a non-monitored varying-speed processor is considered. It is desired that all components execute correctly under normal circumstances, whereas the more important components should execute correctly (although the less important components need not) if the processor runs at any speed no slower than its specified degraded speed.
