Title: Thomas Albert Petersen: Innovator in Data Processing Technologies

Introduction

Thomas Albert Petersen is a notable inventor based in Austin, TX. He holds a total of 18 patents that reflect his significant contributions to the field of data processing technologies. His work has been instrumental in advancing the efficiency and performance of processor systems.

Latest Patents

Among his latest patents is "Data received before coherency window for a snoopy bus." This invention addresses the issue of data availability from devices snooping a load operation. It allows a requesting processor to utilize data prior to the coherency response window, thereby accelerating data processing. The innovation requires minimal changes in processor state transitions, enabling critical data to return to the processor without waiting for the coherency response window.

Another significant patent is "Optimizing pipelined snoop processing." This patent presents a system and method for maintaining cache coherency in symmetric multiprocessor systems. It introduces a separation of logic for performing snoop queries and snoop actions, which enhances throughput by allowing pending snoop queries to proceed without waiting for snoop actions to complete. This innovation includes two state machines: a pipeline state machine for snoop queries and a snoop action state machine for executing the split logic.

Career Highlights

Throughout his career, Thomas has worked with prominent companies, including International Business Machines Corporation (IBM). His experience in such a reputable organization has contributed to his expertise in the field of data processing.
