Title: Masami Jikihara: Innovator in Information Processing Systems
Introduction
Masami Jikihara is a notable inventor based in Yamato, Japan. She has made significant contributions to the field of information processing systems, holding a total of 4 patents. Her work focuses on enhancing data transfer and process request arbitration systems.
Latest Patents
One of her latest patents is a bus system for an information processing system and method of controlling. This innovation allows for controlled data transfer among multiple modules on a common bus. In response to a bus use request from a module, a command is issued to abort data transfer from another module with a lower priority. The module transferring the data responds to the abort command by signaling that the word being transferred is the final word. Data is then transferred between a master and a slave through an address bus that matches the data width, synchronized with a clock from a bus controller.
Another significant patent is a process request arbitration system that preferentially maintains multiple process requests generated from processing units, such as direct memory access (DMA) channels. This system is controlled by a preference circuit based on the priority level assigned to each processing unit. The highest priority processing unit's information and its priority level are stored in latches. Other process requests with the same priority level are inhibited from being supplied to the preference circuit, ensuring that the first generated request is executed before others of the same priority.
