Latest Patents

Arnold's latest patents include a method for insuring data consistency between a plurality of cache memories and the main memory in a multi-processor computer system. This innovative method is capable of detecting predefined data inconsistency states during data transaction requests and correcting them to ensure operations are executed correctly. The method addresses two types of data inconsistency states: one where a request for an operation from a system unit to main memory encounters stale data in the cache, and another where a read operation may return stale data from main memory.

Another significant patent involves the synchronization and processing of memory access operations in a multiprocessing computer system. This system control unit (SCU) manages locked memory access requests, ensuring that multiple central processing units (CPUs) and I/O units operate in parallel relative to a common main memory. The SCU utilizes a lock directory to manage memory access requests efficiently, ensuring fairness in processing denied lock requests.
