Abstract
Managing task execution in a multi-core processor may be achieved by employing a spinlock and a multi-processor priority ceiling protocol. The spinlock may be employed to effect a dynamically enforceable mutual exclusion constraint. The multi-processor priority ceiling protocol may be employed to effect the dynamically enforceable mutual exclusion constraint to synchronize a plurality of tasks executing in the first and second processing cores of the multi-core processor.
