Abstract
A mutual exclusion control is performed with dynamically, allocated lock variables. A lock request circuit issues a lock acquisition request or an unlock request. A lock identifying information holding circuit holds an identifying information related to a currently valid lock. A lock identifying information comparing circuit judges whether or not a lock identifying information from the lock request circuit is included in the lock identifying information holding circuit. A lock identifying information updating circuit updates the lock identifying information holding circuit on the basis of the request from the lock request circuit.
