On Interrupt Strategy from the Point of View of System Efficiency

Interrupt strategy of an operating system can help computer to tackle with urgent or important events,and to run programs in a reasonable fashion in order to achieve a satisfactory performance.But a sophisticated strategy will cause an amount of system costs.In this paper we introduce the concept of “layered interrupt priorities”which will care both the system costs and the response capability.This strategy can be applied in timesharing systems,realtime systems,or multiprocessor systems.At the end of the pa…
