Title: The Innovative Mind of Darrell Sellers

Introduction

Darrell Sellers is a notable inventor based in San Diego, CA. He has made significant contributions to the field of computer technology, particularly in the area of fault tolerance. With a total of 2 patents, his work focuses on enhancing the reliability of computer systems.

Latest Patents

One of Darrell Sellers' latest patents is titled "Functional Interrupt Mitigation for Fault Tolerant Computer." This innovative method addresses the detection and correction of environmentally induced functional interrupts, commonly referred to as 'hangs,' in computers or microprocessors. These issues are often caused by external sources of single event upsets (SEUs) that can disrupt the internal control functions of a microprocessor. The solution he proposes, known as the Hardened Core (or H-Core), involves adding an environmentally hardened circuit to the computer system. This circuit is connected to the microprocessor to monitor and reset it when a functional interrupt occurs.

Additionally, the Hardened Core method can be integrated with another technique called Time-Triple Modular Redundancy (TTMR). This method leverages very long instruction word (VLIW) style microprocessors, which provide externally controllable parallel computing elements. By combining time redundant and spatially redundant fault error detection and correction techniques, TTMR offers a single microprocessor solution that replaces traditional multi-processor redundancy methods, such as Triple Modular Redundancy (TMR).
