Introduction

Stephen J Jourdan is a notable inventor based in Portland, OR. He has made significant contributions to the field of microprocessor technology, holding 2 patents that showcase his innovative approach to enhancing computer processing efficiency.

Latest Patents

One of his latest patents is titled "Trace indexing via trace end addresses." This invention introduces a new class of traces for a processing engine, known as 'extended blocks.' These extended blocks feature an architecture that allows for multiple entry points but only a single exit point. The indexing of these extended blocks is based on the address of the last instruction, which provides several advantages, including a reduction of instruction redundancies, dynamic block extension, and the sharing of instructions among various extended blocks.

Another significant patent by Jourdan is "Intra-instruction fusion." This innovation focuses on fusing micro-operations (uops) together to increase cache memory storage efficiency and computer instruction processing bandwidth within a microprocessor. The process involves fusing uops, storing them in cache memory, un-fusing them, executing in parallel, and retiring them in order to optimize both cost and performance.
