Title: Innovations of Kozo Nuriya

Introduction

Kozo Nuriya is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of microprocessors and digital signal processing. With a total of three patents to his name, Nuriya's work has had a notable impact on technology.

Latest Patents

One of Nuriya's latest patents is a microprocessor and method of testing the same. This microprocessor includes an assign function for assigning ports to a mode identifying unit, a test signal input unit, and a test result signal output unit. It also features a test implement function for sending test results to the test result signal output unit based on test data signals from the test signal input unit. Additionally, it has an activation control function that activates the test implement function upon identifying a test mode by the status of the mode identifying unit. When a test mode signal from test equipment is received, the test signal input unit and the test result signal output unit are assigned to different ports of the microprocessor.

Another significant patent is the multi-stage noise shaping over-sampling D/A converter. This invention involves a noise shaping quantization D/A converter where an input digital signal is supplied to a single-integration sigma delta modulation circuit. The quantization error signal from this circuit is then supplied to a double-integration noise shaping quantization circuit. The output signal from the double-integration circuit is differentiated and summed with the single-integration circuit output to obtain a bit-compressed digital signal for D/A conversion. This innovation eliminates the offset of the analog output signal during a zero hold status of the input digital signal and increases the efficiency of supply voltage utilization, along with an improved signal-to-noise ratio.
