Title: Yukikazu Matsuo: Innovator in Program Counter Circuits

Introduction

Yukikazu Matsuo is a notable inventor based in Hyogo, Japan. He has made significant contributions to the field of electronics, particularly in the development of program counter circuits. With a total of 3 patents to his name, Matsuo's work has had a lasting impact on technology.

Latest Patents

One of Matsuo's latest patents is a program counter circuit. This circuit is composed of two types of registers, a down counter, an up counter, a selector, and a logic circuit. The registers hold pre-jump and post-jump PC values as prescribed by a program. The down counter maintains the number of repetitions for a sequence, while the up counter counts up for each clock pulse. The selector determines which PC value to output next, and the logic circuit generates signals to guide this selection process.

Another significant patent is a test pattern generation circuit and method for use with a self-diagnostic circuit. This circuit produces a test pattern using a microinstruction code, which is temporarily stored in a memory device. The circuit outputs two different instruction codes within one clock cycle. A selector receives the output from the memory device and selectively delays the instruction codes, while a pattern generation circuit produces a corresponding test pattern.
