Abstract
A method of controlling read and write access to a memory structure involves initiating a read lock by obtaining a reader pool ID for a thread from a fixed pool of readers, waiting for a writer to finish by entering a wait-loop and querying a scheduler to reschedule the thread if current wait time exceeds a threshold value, declaring a resource to be read, checking for an active write lock and returning the reader pool ID for the thread. Initiating a write-lock involves checking for an active write lock flag and an active read lock flag and entering a wait-loop if the active write lock flag or the active read lock flag is present, and querying a scheduler to reschedule the thread if the wait time exceeds the threshold value.
