Title: Innovations of Shinya Katoh
Introduction
Shinya Katoh is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of information processing systems, holding a total of four patents. His work primarily focuses on enhancing the efficiency and reliability of processor communication.
Latest Patents
One of his latest patents is an information processing system that features a TMR (Triple Modular Redundancy) unit. This unit connects multiple processors via a bus, allowing them to execute the same processing operation simultaneously. Among these processors, one acts as the master while the others serve as slaves. The information generated by the master processor is outputted to the bus, and each processor is equipped with a multiplex control circuit. This circuit compares the output information from the processor with the bus information, enabling it to detect failures and execute necessary processes.
Another significant patent is an arbitration circuit designed to manage requests from multiple processors. This round-robin arbitration circuit can handle N requests and includes a register that stores one of N values. A priority encoder selects one of N priority patterns based on the value in the register, assigning priorities to the requests accordingly. The circuit updates the register's value in a predetermined order during arbitration and at regular intervals that are asynchronous with the arbitration. This design ensures that even if a live-lock situation occurs, it can be resolved by making a jump in the updating order of the values.
