Latest Patents
One of Rubinfeld's latest patents is titled "Interface between processor and special instruction processor in digital." This invention describes a processor and auxiliary processor designed for use in a digital data processing system. The auxiliary processor is responsible for processing selected instructions, such as floating point instructions. The two processors are interconnected through status lines, data lines, and a bus, allowing for efficient communication and data transfer. When the primary processor initiates a selected instruction, it sends the operation code to the auxiliary processor and enables the transfer of operands. The auxiliary processor then signals when it has completed the instruction and sends back the results.
Another significant patent is "System for controlling the storage of information in a cache memory." This invention provides a system for managing information storage in cache memory. It features a processor connected to a bus, which includes information signal transfer lines and a cache control signal transfer line. The processor contains a cache memory and a bus interface circuit that facilitates the transfer of information signals to the cache memory. The cache control circuit determines whether the received information should be stored in the cache memory based on the conditions of the cache control signal.
