Abstract
A method for providing mutual exclusion at a single data element level for use in embedded systems. Entries for tasks that are currently holding a resource are stored in a hold list. Entries for tasks that are not currently executing and are waiting to be freed are stored in a wait list. A single mutual exclusion semaphore flags any request to access a resource.
