How to Use the CoreMark®-PRO Benchmark

Описание

NOTE: This video contains a lot of small text and must be watched at 720p or 1080p (preferred) resolution, otherwise you'll just see lots of colorful blurs!

This detailed walk-through explains how to run CoreMark-PRO out-of-the-box on Linux, and how to port (and optimize) it to an STMicroelectronics MPU. Viewers should have a basic understanding of CoreMark-PRO, please refer to the documentation on its GitHub repository at: https://github.com/eembc/coremark-pro

Part 1 walks the viewer through a simple make-based build and explores parallelism on Linux system.

Part 2 focuses on an embedded port, is presented from the perspective of a first-time developer, showing common compiler warnings and errors, and explaining how to fix each one. Once functionality has been achieved, the tutorial demonstrates simple, first-order optimizations: compiler settings, clock tree, and cache enabling.
