Mutex Priority Inheritance in Real-Time Systems

1. Introduction The core objective of real-time systems is to ensure that tasks are completed at the correct times and within specified time limits. In the design of real-time systems, not only is functional correctness required, but when to start and when to finish are also important considerations. To achieve this goal, compared to general … Read more
