Overview
+
+
+

CMSIS-Core (Cortex-M) implements the basic run-time system for a Cortex-M device and gives the user access to the processor core and the device peripherals. In detail it defines:

+
    +
  • Hardware Abstraction Layer (HAL) for Cortex-M processor registers with standardized definitions for the SysTick, NVIC, System Control Block registers, MPU registers, FPU registers, and core access functions.
    • +
  • System exception names to interface to system exceptions without having compatibility issues.
    • +
  • Methods to organize header files that makes it easy to learn new Cortex-M microcontroller products and improve software portability. This includes naming conventions for device-specific interrupts.
    • +
  • Methods for system initialization to be used by each MCU vendor. For example, the standardized SystemInit() function is essential for configuring the clock system of the device.
    • +
  • Intrinsic functions used to generate CPU instructions that are not supported by standard C functions.
    • +
  • A variable to determine the system clock frequency which simplifies the setup the SysTick timer.

CMSIS supports the complete range of Cortex-M processors (with exception of Cortex-M1) and the Armv8-M architecture including security extensions.

+

+Cortex-M Reference Manuals

+

The Cortex-M Device Generic User Guides contain the programmers model and detailed information about the core peripherals and are available for:

+ +

The Cortex-M23 and Cortex-M33 are described with Technical Reference Manuals that are available here:

+ +

+Armv8-M Architecture

+

Armv8-M introduces two profiles baseline (for power and area constrained applications) and mainline (full-featured with optional SIMD, floating-point, and co-processor extensions). Both Armv8-M profiles are supported by CMSIS.

+

The Armv8-M Architecture is described in the Armv8-M Architecture Reference Manual.
