11. ARM CMSIS and Software Drivers
The ARM Cortex Microcontroller Software Interface Standard (CMSIS) is a comprehensive framework facilitating the development of ARM-based microcontrollers. It provides standardized APIs and drivers that enhance portability, reduce development time, and simplify hardware interaction. The chapter covers key components of CMSIS, including CMSIS-Core, CMSIS-RTOS, and CMSIS-DSP, while also discussing the integration of CMSIS with real-time operating systems and performance optimization techniques.
