In computer science, the test-and-set CPU instruction is used to implement mutual exclusion in multiprocessor environments. Although a correct lock can be implemented with test-and-set, it can lead to resource contention in busy lock (caused by bus locking and cache invalidation when test-and-set operation needs to access memory atomically). To lower the overhead a more elaborate locking protocol test and test-and-set is used. Given a lock: boolean locked := false // shared lock variable Entry protocol is: Exit protocol is: procedure ExitCritical { locked := false}
