Latest Patents: Donna J Plunkett holds 1 patent for her invention titled "System architecture for improved message passing and process." This patent describes a system and method for interprocess communication between concurrently executing, cooperating sequential processes in a digital computer system. The invention utilizes a shared memory queue as a mechanism for message passing and process synchronization. Data is transferred from a sending process to a receiving process through a queue entry, which is visible in the virtual address space of the first process. The sending process directs the processor to execute an enqueue instruction to add the queue entry, while the receiving process removes it by executing a dequeue instruction. This innovative approach allows the receiving process direct access to the contents of the queue entry without needing to copy the data into its virtual address space. Additionally, the system provides protection against unauthorized access to the queue by other processes active in the system.
