Title: Kimio Ooe: Innovator in Address Translation and Logic Simulation
Introduction
Kimio Ooe is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the fields of address translation and logic simulation, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of Kimio Ooe's latest patents is an address translation apparatus having a memory access privilege check. This apparatus includes a memory for storing multiple physical addresses and a content addressable memory unit that stores signal pairs corresponding to these addresses. Each signal pair consists of a logical address and memory protection level data. The apparatus is designed to search for a signal pair with a logical address that matches the one being translated and to compare memory protection level data based on a privilege level allocated to the requesting program. This innovation enhances memory access security and efficiency.
Another significant patent by Ooe involves a logic simulation method for logic circuits with unknown internal logic. This method utilizes the actual circuit to set its internal status to an objective state using interrupt operations. Input signal values are then applied to obtain resultant outputs. For circuits without unknown internal logic, software logic simulation is performed, calling the actual circuit when necessary. This dual approach allows for more accurate and efficient logic simulations.
Career Highlights
Throughout his career, Kimio Ooe has worked with prominent companies such as Hitachi, Ltd. and Hitachi Microcomputer Engineering, Ltd. His experience in these organizations has contributed to his development as an inventor and innovator in the technology sector.
