Method and apparatus to clear semaphore reservation |
摘要 |
Semaphore operation manages exclusive access to a memory that is shared by a plurality of processing elements. Semaphore reservation status for exclusive access by a processing element is monitored by a memory controller. To clear an obsolete reservation status, a command signal is transmitted for a write operation to the memory while prohibiting update of the contents of a memory. The reservation status at the controller is changed from a reservation state to a non-reservation state in response to receipt of the command signal.
