Latest Patents:

The patent held by James A. Steffen is titled “Virtual memory cache for use in multi-processing systems.” This innovative system addresses the critical challenge of maintaining data consistency among distributed processors, each having its associated cache memory. The unique approach allows a processor to access data in its cache by specifying the virtual address, enabling an associative search of cache cells. Each cell in this system contains a virtual address, a real address, flags, and multiple associated data words. In instances where the processor's virtual address does not yield a hit, a map processor provides the corresponding real address for cache access. Additionally, when a processor writes data into the cache, the system ensures that all other caches sharing that data are updated before permitting any local cache write. This patent showcases Steffen's commitment to enhancing computational efficiency and data management.
