QUESTION

What is the Cortex Microcontroller Software Interface Standard and where can I download the files?

ANSWER

The Cortex Microcontroller Software Interface Standard (CMSIS) answers the challenges that are faced when software components are deployed to physical microcontroller devices based on a Cortex-M1 or Cortex-M3 processor. The CMSIS will be also expanded to future Cortex-M processor cores (the term Cortex-Mx is used to indicate that). The CMSIS is defined in close co-operation with various silicon and software vendors and provides a common approach to interface to peripherals, real-time operating systems, and middleware components.

ARM provides as part of the CMSIS the following software layers that are available for various compiler implementations:

These software layers are expanded by Silicon partners with:

CMSIS defines for a Cortex-M3 Microcontroller System:

By using CMSIS compliant software components, the user can easily re-use template code. CMSIS is intended to enable the combination of software components from multiple middleware vendors.

The CMSIS Version 1.0 files can be downloaded as attachment from this Knowledgbase article.
