Abstract
The present teaching, which includes methods, systems and computer-readable media, relates to controlling access to a shared resource including, for example, a memory unit. The disclosed techniques may include receiving a configuration parameter relating to a relationship between read and write requests that are initiated by concurrent processes and stored in read and write queues, respectively, for accessing the shared resource. The techniques may further include determining, based on the configuration parameter, whether to allow a read request or a write request to be executed using the shared resource, and providing to a concurrent process access to the shared resource for executing the allowed read or write request. Further, upon a completion of executing the allowed read or write request, a return token on a return token queue different from the read and write queues may be received, the return token corresponding to the allowed read or write request.
