Title: The Innovations of Robert A. Kohtz

Introduction

Robert A. Kohtz is a notable inventor based in St. Joseph, MI (US), recognized for his contributions to the field of computer systems. With a total of 16 patents to his name, Kohtz has made significant advancements in technology, particularly in multiprocessing systems.

Latest Patents

One of his latest patents is a multiprocessor system designed for enabling shared access to a memory. This innovative system provides multiplexed address and data paths from multiple CPUs to a single storage device. The paths are controlled by an arbitration circuit that ensures one CPU always has the highest priority. The primary CPU may or may not be the highest priority CPU in the arbitration scheme. The arbitration circuit is integrated with a controlling mechanism that interfaces with the memory device. This controller operates at a clock rate sufficient to allow the highest priority CPU to access the memory at its maximum data rate while guaranteeing a maximum idle period for lower priority CPUs waiting for their interleaved memory access to complete. The use of a single memory device results in cost and space savings. The controller is responsive to the processors, multiplexing their information signals to selectively convey information present at their address and data ports. A common memory device is addressable by the processors and is responsive to the controller for shared addressing.

Career Highlights

Throughout his career, Kohtz has worked with several prominent companies, including Zenith Data Systems Corporation and Packard Bell NEC. His experience in these organizations has contributed to his expertise in developing innovative technologies.

Collaborations

Kohtz has collaborated with notable individuals in the field, including David J. DeLisle and Lloyd W. Gauthier. These collaborations have likely enriched his work and led to further advancements in technology.
