Pipeline Performance Testing

Concept

Pipeline Performance Testing is a proposed CPU verification approach in which a higher-level model of pipeline scheduling and performance is used to analyze the timing of committed instruction traces, with the goal of finding performance bugs and tracking performance improvements.

Overview

Pipeline Performance Testing refers to testing CPU pipeline behavior by comparing or analyzing the timing of instruction traces committed in a pipeline against a higher-level model of pipeline scheduling and performance. The cited TestRIG paper describes this approach as a way to discover performance bugs and track performance improvements. It also notes that direct instruction injection offers a high level of control that should enable precise detection of performance anomalies.
