System and method to provide single thread access to a specific memory region

A non-transitory machine-readable medium having stored thereon data, which if executed by a processor, causes the processor to perform a method, the method comprising:

• allocating a predetermined range of memory locations, the memory locations including a first memory location to provide storage for a mutex token and a plurality of second memory locations, each to provide temporary data storage;
• reading, by a requester attempting to access the plurality of second memory locations, the first memory location to determine availability of the mutex;
• if the mutex is available,
• allowing possession of the mutex by the requester;
• enabling read/write access to the requester to the plurality second memory locations;
• and
• if the mutex is unavailable, denying possession of the mutex by the requester.

A method, comprising:

• allocating a predetermined range of memory locations within a processor, the memory locations including a first memory location to provide storage for a mutex token and a plurality of second memory locations, each to provide temporary data storage;
• reading, by a requester attempting to access the plurality of second memory locations, the first memory location to determine availability of the mutex;
• if the mutex is available,
• allowing possession of the mutex by the requester;
• enabling read/write access to the requester to the plurality second memory locations;
• and
• if the mutex is unavailable, denying possession of the mutex by the requester.

A system, comprising:

• system memory to store at least one of instructions and data;
• a processor coupled to said system memory, said processor including
• a first memory location to store a mutex, possession of the mutex by one of a plurality of requesters to enable read/write access to a predetermined range of second memory locations for a mutex possessing requester;
• logic to allow mutex possession by a requester if the mutex is available;
• logic to deny mutex possession by a requester if the mutex is unavailable;
• logic to disable read/write access to the predetermined range of second memory locations for a requester not in possession of the mutex, the circuitry to return a predetermined error code to the non-possessing requester for attempts by the non-possessing requester to access the predetermined range of second memory locations;
• logic to release possession of the mutex by a mutex possessing requestor upon completion of a processing task by the mutex possessing requester.
