## What it is
CoreMark is EEMBC's industry-standard benchmark for measuring CPU and embedded microcontroller performance, testing core processor features with a small, portable C codebase. It is built and run via make, with porting files for cross-compiling to bare-metal or OS-less platforms.

## Use cases
- benchmark my cpu's core performance
- compare microcontroller performance across chips
- measure embedded processor speed
- run a standard cpu benchmark for reporting
- evaluate compiler optimization impact on cpu performance
- benchmark a bare-metal mcu without an os

## When to choose
- you need an industry-recognized, comparable CPU core benchmark score
- you are evaluating embedded MCUs or cross-compiled targets
- you want a small, simple benchmark that isolates processor core features

## When to avoid
- you need whole-system or application-level benchmarks (use CoreMark-PRO or SPEC)
- you need GPU, memory, or I/O performance measurement
- you need a benchmark with large datasets from real applications

## Facets
- artifact type: cli-tool
- maturity: stable
- function: benchmarking
- domain: performance, embedded-systems, developer-tools
- platform: cross-platform, embedded, cli
- tags: cpu-benchmark, microcontroller, eembc, c, industry-standard, linux
