Latest Patents

Storage Control System Using Plural Buffer Address Arrays. This invention coordinates updates to two buffer address arrays in a data processing system where multiple processors share storage. It updates the second array before the first in response to specified block transfers and storage operations, and allows a new access request once the relevant transfer is complete and the first array has been updated.

Device for Detecting an Overlap of Operands to Be Accessed. This device detects whether operands overlap in a pipeline-controlled data processing system. It compares addresses associated with store and fetch instructions and evaluates access width, stored address information, and fetch data length to determine whether an overlap exists, helping preserve instruction execution order.

Career Highlights

Shiozaki’s listed inventions address processor coordination, buffer management, and operand access in computer systems. These areas are important to reliable data processing, particularly when multiple processors or pipelined instructions operate on shared resources.

Collaborations

Shiozaki is associated with Hitachi, Ltd. His listed coworkers include Kanji Kubo and Tomoatsu Yanagita.

Conclusion

Kenichi Shiozaki’s patent work reflects a focus on data processing systems, including storage control and the detection of overlapping operands.
