Title: Hisamitsu Tanihira: Innovator in Central Processing and Bus Interface Technologies

Introduction

Hisamitsu Tanihira is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the fields of central processing and bus interface technologies. With a total of 6 patents to his name, Tanihira's work has had a lasting impact on the industry.

Latest Patents

Tanihira's latest patents include a method and apparatus for setting the status mode of a central processing unit. This innovation involves writing data for designating a status mode in a data portion of a data-type microinstruction. Upon powering up, the data-type microinstruction is read, and a status-mode setting circuit generates an enable signal. This enable signal is crucial as it is only generated during the initial reading of the data-type microinstruction. The status-mode designating data is then stored in a status-mode memory, allowing the central processing unit to execute processing according to the read status mode.

Another significant patent is related to a bus interface structure and system for controlling the bus interface. This system comprises a bus interface, a common memory, a local bus, and a memory controller. The memory controller, equipped with a buffer, connects to the local bus. The bus interface features a burst disassembling control circuit that disassembles burst transfer data into block transfers and one-word transfers. This ensures that when the bus interface receives all requested data from the common memory during a read access, it adds information on a destination device and sends the requested data via the system bus.
