About CoreMark®-PRO

CoreMark-PRO is a comprehensive, advanced processor benchmark that works with and enhances the market-proven industry-standard EEMBC CoreMark® benchmark. While CoreMark stresses the CPU pipeline, CoreMark-Pro tests the entire processor, adding comprehensive support for multicore technology, a combination of integer and floating-point workloads, and data sets for utilizing larger memory subsystems. Together, EEMBC CoreMark and CoreMark-PRO provide a standard benchmark covering the spectrum from low-end microcontrollers to high-performance computing processors.

More details about the workloads can be found in the CoreMark-PRO GitHub repository.

Porting Guides

An application note explaining how to port CoreMark-PRO to bare-metal (no operating system) can be found here.

We've also created a tutorial video on YouTube with examples for Linux and an STM32 device. Please view in HD (720p or 1080p) since the video contains a lot of small text.

Comparing CoreMark and CoreMark-PRO

The EEMBC CoreMark-PRO benchmark contains five prevalent integer workloads and four popular floating-point workloads. The integer workloads include JPEG compression, ZIP compression, an XML parser, the SHA-256 Secure Hash Algorithm, and a more memory-intensive version of the original CoreMark. The floating-point workloads include a fast Fourier transform (FFT), a linear algebra routine derived from LINPACK, a greatly improved version of the Livermore loops benchmark, and a neural net algorithm to evaluate patterns.

Together, the workloads in CoreMark-Pro represent a wide diversity of performance characteristics, memory utilization, and instruction-level parallelism. This benchmark is guaranteed to highlight the strengths — and weaknesses — of any processor.
