Latest Patents

Sielaff holds a patent for a "Method and apparatus for locking shared memory locations." This invention presents a method of synchronizing accesses to shared data in a multiprocessing system that possesses atomic swap capabilities. The process involves defining a distinguished lock value, which a processor uses to access shared data memory locations. By performing an atomic swap of the lock value, the processor can determine if the memory location is already locked by another processor. If the lock value is detected, the processor continues to attempt the atomic swap until it can access the data. Once the processor has access, it updates the shared data memory location accordingly. In cases where a unique lock value cannot be defined, Sielaff's method includes creating an array to store lock values associated with specific shared data memory locations.
