# CMSIS-Core Validation

This repository contains a test suite that validates CMSIS-Core implementations. It uses [**Fixed Virtual Platforms**](https://developer.arm.com/Tools%20and%20Software/Fixed%20Virtual%20Platforms) to run tests to verify correct operation of the CMSIS core functionality on various Arm Cortex-M based processors.
