Latest Patents

Wetzel's latest patents include a "Store-in-cache processor means for clearing main storage" and a "Multiprocessor mechanism for handling channel interrupts." The first patent describes a system that prevents a store-in-cache (SIC) from requesting or receiving any line fetch from main storage (MS) when a clear line (CL) command is issued by a CPU. This invention provides two CPU modes: an initial storage validation mode and an instruction processing mode, allowing for efficient execution of commands during system initialization and program instruction processing. The second patent focuses on the multiprocessor handling of multiple queues of pending I/O interrupt requests in a shared main storage environment. It details how an input/output processor (IOP) manages these requests and how central processors (CPs) handle them based on priority, ensuring effective interrupt management.
