Title: Haruyasu Okubo: Innovator in Data Processing Technologies
Introduction
Haruyasu Okubo is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of data processing, holding 2 patents that showcase his innovative approach to technology. His work focuses on enhancing the efficiency and functionality of data processors and processing systems.
Latest Patents
Okubo's latest patents include a data processor and data processing system designed to optimize power consumption while maintaining high performance. This data processor can transition quickly from a low power consumption state to an operating state. It features multiple modes, including a program running state, standby mode, light standby mode, and sleep mode. In sleep mode, the supply of a synchronizing clock signal to the central processing unit (CPU) is halted, while other circuit modules continue to receive the signal. The standby mode suspends the frequency multiplication and operation of the clock pulse generator, stopping the supply of the synchronizing clock signal to both the CPU and other circuit modules. The light standby mode allows for faster transitions to an instruction executable state compared to standby mode, achieving lower power consumption than sleep mode.
Another significant patent is for a data processing device that incorporates an accelerator for digital signal processing. This device utilizes a central processing unit alongside a special-purpose hardware circuit to enhance software operations by partially replacing them with hardware functions. This arrangement is particularly beneficial in mobile communication terminal devices, such as digital cellular portable telephones, where the digital signal processor works in conjunction with the accelerator to perform specific signal processing tasks, like waveform equalization.
