Latest Patents

One of Karp's latest patents is for a modular computer system. This innovative design allows processing elements, memory elements, and peripheral units to be physically added and removed from the system without disrupting its operation or necessitating any reprogramming of the software running on the system. The processing units, memory units, and peripheral units are all coupled to a common system bus by specialized interface units. The processing elements are organized into partially independent groups, each with dedicated interface units, while sharing system resources, including peripherals and the entire memory space. Within each processing element group, supervisory tasks are performed by one of the processors, with the supervisor function passed among the processors in a sequence to prevent a fault in one processor from disabling the entire group. Communication between groups is accomplished via common memory areas, and the transfer of the supervisor function is managed through a common area in one of the dedicated interface units. Access to the common system bus is controlled by the associated interface units using a combination serial/parallel arbitration scheme, which increases arbitration speed without requiring a full complement of request/grant leads.
