| Abstract: | The real- time operating system request the speed tobe quick and the characteristic may be forecast,the real- timeduty must completed in the request time. This paper describes the theory of the scheduler algorithm based on priority bitmap, then it presents an improvement for the scheduler algorithm at the priority levels, the data storage and the tasks in the same level. |
