FreeRTOS is an open-source real-time operating system (RTOS) designed for embedded devices, known for its simplicity, small footprint, and real-time capabilities. It provides a lightweight kernel that allows for task scheduling, inter-task communication, and resource management in embedded systems.

    CMSIS DSP Software Library

    A suite of common signal processing functions for use on Cortex-M and Cortex-A processor based devices. The library is released in source form. It is strongly advised to compile the library using -Ofast to have the best performances. The library functions are declared in the public file arm_math.h which is placed in the Include folder.

  • Basic math functions
  • Fast math functions
  • Complex math functions
  • Filtering functions
  • Matrix functions
  • Transform functions
