Title: Sean P. Cummins: Pioneering Innovations in Branch Prediction and Cache Memory Techniques

Introduction

Sean P. Cummins is a notable inventor based in Sunnyvale, California. He has made significant contributions to the field of technology with two patents to his name. Cummins' work focuses primarily on improving the efficiency of processors through advanced mechanisms and techniques.

Latest Patents

Cummins holds two noteworthy patents that exhibit his innovative prowess. The first patent is a **Branch Prediction Mechanism**, designed to predict the outcome and branch target address of the next possible branch instruction from a current instruction. This mechanism utilizes a branch target buffer (BTB) where each entry provides an address for the next possible branch instruction along with its corresponding branch target address. By comparing the TAG portion of each BTB entry with the current instruction address, the prediction mechanism enhances the accuracy of branch instruction forecasting.

The second patent is an **Instruction Cache Address Generation Technique** that aims to reduce delays in fetching missed data from cache memory. This system employs a pipelined address generation circuit to calculate and apply addresses to cache memory in multiple cycles. While retrieving data from one address, it simultaneously calculates the next address, assuming successful data retrieval. In the event of a cache miss, the missed data is promptly accessed from the main system memory with improved speed, effectively minimizing penalty delay cycles that hamper processor performance.
