摘要
Abstract
μC/OS-Ⅱ does not realise the true priority inheritance protocol to resolve priority inversion. It does not provide an effective solution to solving deadlock either. After improving the task management mechanism, the same-priority-task time slice circular scheduling algorithm is expanded to realise the true priority inheritance protocol. Resource allocation is represented by used resource request and allocation matrix. When a task requesting a resource is blocked, its deadlock is automatically detected and resolved. Through performance analysis and test validation, the effectiveness and timeliness of the improved algorithm is proven.关键词
