Introduction

Minoru Sugano is a notable inventor based in Yokohama, Japan. He has made significant contributions to the fields of memory access control and packet switching technologies. With a total of 2 patents, Sugano's work has had a lasting impact on the efficiency and reliability of data processing systems.

Latest Patents

Sugano's latest patents include a method of direct memory access control and a packet switching equipment and method for controlling. The method of direct memory access control involves a system comprising input/output devices, a memory, and a control processor. In this system, direct memory access information from an input/output device to the processor is temporarily stored, and a direct memory access request is transmitted to the processor. This innovation reduces the processor bus holding time at direct memory access, thereby improving the processing speed of the processor.

The packet switching equipment and method aim to facilitate the expansion of a packet-switched network and allow for easy constitution changes in a multistage switched network. This invention includes a packet data terminal, packet switching equipment, PBX, multiplexer, LAN, and voice communication apparatuses. The basic switching modules, known as configuration units, are interconnected to form a hierarchic tree structure, with the number of hierarchic levels selectable based on the size of the packet-switched network. Additionally, to enhance the reliability of packet data transfer, multiple connecting lines are established between bit switches and upper-level configuration units, creating a redundant configuration.
