WebApr 1, 2024 · Some operating systems use the same word critical section in the API. Usually a mutex is a costly operation due to protection protocols associated with it. At last, the objective of mutex is atomic access. There are other ways to achieve atomic access like disabling interrupts which can be much faster but ruins responsiveness. WebConsequently, it’s important to disable interrupts sparingly, and only when absolutely necessary (and, naturally, to remember to enable interrupts again after the section of critical code). Other methods of maintaining data coherency will be discussed in the section on real-time operating systems. 3 Software Architectures for Embedded Control ...
