| Abstract: | By analyzing the timing wheel algorithm, this paper puts forward an improved algorithm for task-delay mechanism for real-time operation system, and tests the performance on NEC78K monolithic processor. Analysis shows that the algorithm is able to enhance the speed of clock interrupt response and the accuracy of clock, then enhance the system＇s real-time response. |
