A Taxonomy of Performance Assurance Methodologies and Its Application in High Performance Computer Architectures

Free registration required

Executive Summary

In this paper, the authors present a systematic approach to the complex problem of high confidence performance assurance of high performance architectures based on methods used over several generations of industrial microprocessors. A taxonomy is presented for performance assurance through three key stages of a product life cycle-high level performance, RTL performance, and silicon performance. The proposed taxonomy includes two components-independent performance assurance spaces for each stage and a correlation performance assurance space between stages. It provides a detailed insight into the performance assurance space in terms of coverage provided taking into account capabilities and limitations of tools and methodologies used at each stage.
