Introduction

Spyros Lyberis is a notable inventor based in Cambridge, GB. He has made significant contributions to the field of data processing, holding a total of 4 patents. His work focuses on enhancing the efficiency and reliability of software testing and data processing systems.

Latest Patents

One of his latest patents involves checksum generation. This apparatus includes processing circuitry that performs data processing in response to instructions. It features at least one control storage element to store internal state for controlling the operation of the processing circuitry. Additionally, it has checksum generating circuitry that generates a checksum based on at least one item of internal state stored in the control storage element. The generated checksum is stored in a diagnostic storage location, making it accessible to a diagnostic control agent, such as software executing on the processing circuitry or an external device. This innovation significantly improves the design of software test libraries for detecting hardware faults.

Another recent patent by Lyberis pertains to software test program generation. This process involves simulating a software test program executing on a primary model of a portion of a data processing apparatus to identify uncovered failures. A formal method analysis is then conducted on a combination of the primary model and a fault-simulating model to identify software stimuli that can render the uncovered failures detectable. The identified software stimuli are incorporated into the software test program to enhance failure coverage. This iterative process continues until the desired level of failure coverage is achieved.
