Latest Patents
Hassler's latest patents include a method and apparatus for cache memory access with separate fetch and store queues. This innovative two-way set associative cache memory system is designed for parallel-pipelined computer systems. It utilizes separate queue structures to manage main memory fetch and store requests generated by the central processing unit (CPU). The memory access unit, which connects the cache memory system and the CPU, selects the next request to be processed from the heads of the fetch and store queues. The system prioritizes fetch requests unless the memory partition for the fetch request is busy, while the store request partition is idle. Data retrieved from main memory is managed according to an algorithm that favors empty pages and minimizes pending update requests. This ensures efficient data handling and enhances overall system performance.
