Title: Bernard C. Dewitt: Innovator in Data Processing Systems

Introduction

Bernard C. Dewitt is a notable inventor based in Austin, TX, recognized for his contributions to data processing systems. He holds a total of 3 patents, showcasing his innovative approach to technology and engineering.

Latest Patents

One of his latest patents involves a data processing system that utilizes scan testing with set latches. This system employs a scannable test circuit to conduct transistor fault testing on a large amount of random transistor logic. During the test mode, multiple Master-Slave latches are utilized to observe the output of various data path drivers activated during the scan test operation. The outputs of these drivers are connected to the Master portion of the latches, allowing for effective testing and fault information retrieval.

Another significant patent focuses on sticky bit detection and shifting logic. This circuit performs bit shifting for floating-point arithmetic while concurrently determining the presence of sticky bits. An input data operand is processed alongside a control signal that dictates the number of digit positions to shift. As bits are shifted, the circuit detects any bits that are shifted off, providing both a shifted output operand and a sticky bit detect signal simultaneously. The efficient layout of this circuit minimizes the area required for implementation.
