Latest Patents
One of Don W Rain's latest patents is titled "Internal performance monitoring by event sampling." This patent provides event-controlled operations for an internal hardware/software monitor for a processor in a data processing system. It embeds and distributes at least one instrumentation table unit (ITU) in each processor, along with event detection circuitry to collect event-sampled hardware signals. The monitoring is centrally controlled, and the sampling of CPU signals is done at the occurrence rate of selected events. The ITUs operate asynchronously within the system, allowing for efficient event-driven monitoring.
Another significant patent is "Page storage control methods and means." This invention introduces an independent data bus path between random access page storage (PS) and main storage (MS). This bus does not pass through any channel processor (CH) or central processor (CP). The patent allows for asynchronous control of page data transfers by a channel processor or synchronous control by a central processor. Novel instructions enable the central processor to manage page transfers effectively, enhancing the overall data processing capabilities.
