CoreMark

Concept WIKI v2 · 6/14/2026

CoreMark is a processor benchmark used to evaluate CPU core performance in multiple RISC-V and ASIC design works, including a RISC-V CPU verification thesis, a CVA6 superscalar performance study, and the KASIRGA-KIZIL TEKNOFEST 2023 chip design. The name is also shared by an unrelated text-watermarking framework, which must be distinguished from the benchmark.

Overview

CoreMark is a benchmark used to evaluate processor performance. In the available evidence, it appears in at least three distinct RISC-V / digital-processor design works: (1) a UVM-based RISC-V CPU core verification thesis, (2) a CVA6 RISC-V superscalar performance-modeling paper, and (3) the KASIRGA-KIZIL processor project from TEKNOFEST 2023. The same spelling is also used by an unrelated text-watermarking framework, which is a separate concept and should not be conflated with the benchmark.

Role in the cited RISC-V verification work

In the thesis UVM based design verification of a RISC-V CPU core (Politecnico di Milano), CoreMark appears as subsection 5.3.2 Coremark, under the broader 5.3 Benchmarks section of Chapter 5 Experimental evaluation, alongside subsection 5.3.1 Dhrystone. The benchmarks section is positioned after instruction-set compliance tests (5.1) and direct tests (5.2), and before fuzzing (5.4). The available evidence only confirms the document structure; the body of section 5.3.2 itself is not included in the provided chunks, so specific scores, workload characteristics, or methodology for CoreMark in this thesis cannot be stated from the evidence.

Role in the CVA6 performance modeling paper

In Using a Performance Model to Implement a Superscalar CVA6 (arXiv:2410.01442v1), CoreMark is used as the validation and evaluation workload for a CVA6 RISC-V processor performance model built before RTL implementation. The reported model accuracy on CoreMark is 99.2%, and the superscalar feature that was subsequently implemented produced a CVA6 performance improvement of 40% on CoreMark.

Role in the KASIRGA-KIZIL processor project

The KASIRGA-KIZIL team (TOBB ETÜ) won first place in the TEKNOFEST 2023 Çip Tasarım Yarışması, Sayısal İşlemci Kategorisi (digital processor category), with the KIZIL İşlemci processor design. The project's GitHub repository presents a CoreMark Karşılaştırma Grafiği (CoreMark comparison chart) as part of the documented processor results, indicating that CoreMark is used as one of the comparative performance metrics for the KIZIL processor. Specific numerical CoreMark scores from the chart are not extractable from the provided textual evidence.

Distinction from the text-watermarking "CoreMark"

The name CoreMark is also used for CoreMark: Toward Robust and Universal Text Watermarking Technique (arXiv:2506.23066v2), which is a watermarking framework for text based on consecutively aligned black pixel segments ("COREs") embedded by modifying character thickness. This is a different concept from the processor benchmark and is not related to the CPU-evaluation usage described above.

Relationship to benchmarks

Across the available evidence, CoreMark is consistently categorized as a benchmark-style performance metric, used alongside other evaluation methodologies (Dhrystone, instruction-set compliance, direct tests, fuzzing, superscalar comparison charts).

Evidence limitations

The provided chunks do not include the CoreMark subsection body of the RISC-V verification thesis, do not include the numeric values from the KASIRGA-KIZIL CoreMark comparison chart, and do not provide the original EEMBC CoreMark specification text. Claims beyond what is explicitly stated above are not supported.
