framework

CMSIS = Cortex Microcontroller Software Interface Standard

• Developed by ARM.
• Provides a standardized software framework for Cortex-M microcontrollers.
• Main purposes:
  • Defines a consistent API across Cortex-M chips.
  • Supplies startup code and core access functions.
  • Provides DSP library and RTOS interface.
  • Simplifies portability of code between different ARM Cortex-M devices.

👉 In short: CMSIS makes programming Cortex-M chips easier, faster, and more portable.
