Latest Patents

One of his latest patents is titled "Protocol for Interrupt Bus Arbitration in a Multi-Processor System." This invention involves a multi-processor system that utilizes an interrupt bus for arbitrating among eligible processors to determine which processor will service an interrupt request. The interrupt bus features wired-OR connection data lines for arbitration. Each processor is associated with a local interrupt controller that manages the acceptance of interrupt request messages. To minimize interruptions of high-priority tasks, the system allows interrupts to be accepted by the processor currently executing the lowest priority task. An arbitration protocol governs the interrupt bus, determining the lowest priority processor through a random priority scheme that updates an arbitration ID with each message.

Another significant patent is the "Multi-Processor Computer System with Interrupt Controllers Providing." This invention describes a multi-processor programmable interrupt controller system that includes an I/O interrupt controller for receiving interrupt requests from an I/O subsystem. It features multiple processor interrupt controllers, each linked to a specific processor for managing accepted interrupts. The system employs an interrupt controller bus for transmitting interrupt requests between units and for bus and priority arbitration, utilizing a standard message format and arbitration protocol. This design enhances system efficiency by relieving the common system bus of interrupt service requests and related traffic.
