Title: Kohji Kawamoto: Innovator in Microprocessor Technology

Introduction

Kohji Kawamoto is a notable inventor based in Itami, Japan. He has made significant contributions to the field of microprocessor technology, holding 2 patents that showcase his innovative approach to computing.

Latest Patents

Kawamoto's latest patents include a microprocessor with reset execution from an arbitrary address. This microprocessor features a built-in instruction ROM and allows arbitrary data to be set in advance in a data register. The data is then provided to a program counter through a register indirect jump instruction. The microprocessor includes both a normal reset function and an additional reset function, which enables reset from a predetermined address. This additional function is activated when the logic level of a control signal input terminal meets specific criteria during the reset signal's clearance. The program can be re-executed using this data as the instruction start address.

Another patent by Kawamoto describes a microprocessor that permits execution to begin from an arbitrary address following a reset signal. In this design, arbitrary data is pre-set in a data register as an address. The address is transferred to the program counter via a register indirect jump instruction that does not originate from the instruction ROM. This microprocessor also features a normal resetting function, which allows re-execution of a program from a predetermined address, such as zero. The normal resetting function is triggered when the control signal input terminal is at a predetermined level when the reset signal is cleared. If the control signal is at a different level, the arbitrary data in the data register is used to set the program counter, allowing the program to be re-executed from that address.
