Title: Atsuhiko Okada: Innovator in Data Transfer Technology
Introduction
Atsuhiko Okada is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of data transfer technology, holding a total of 6 patents. His work focuses on enhancing the efficiency and reliability of data transmission in semiconductor integrated circuits.
Latest Patents
One of Okada's latest patents is a data transfer circuit. This invention involves a transmission unit that loads transmission data onto a first register and outputs it to a transfer line. It starts counting the transmission clock signals in a strobe generation counter according to a transmission clock signal. When the counted value reaches a set value, a strobe signal is output. A reception unit then loads the transfer data onto a second register according to a reception clock signal. An edge detection unit generates a valid signal with a pulse width corresponding to one cycle of the reception clock signal when the strobe signal is detected. A third register loads the data output from the second register and outputs it as reception data according to the reception clock signal when the valid signal is supplied.
Another notable patent is for a mixed-voltage interface and semiconductor integrated circuit. This invention allows for the serial transfer of signals between circuit blocks operating at different voltage levels within a semiconductor integrated circuit. Control, address, and data signals are multiplexed onto a common signal line, significantly reducing the number of necessary signal lines compared to parallel signal transfer. This innovation also allows for a separate electrostatic discharge protection circuit for each signal line without requiring excessive space for protection circuitry.
