This version of the course focuses on developing DSP algorithms for ARM microcontrollers leveraging the microcontrollers features such SIMD, MAC, Floating Point Unit (FPU) and the ARM CMSIS-DSP Library. In IAR Embedded Workbench for Arm, you enable the use of the CMSIS-DSP library by first choosing a Cortex-M device, for example the Arm Cortex-M4F device STM32F407ZG. Second, set the CMSIS-DSP library option in the General Options>Library Configuration page. This will set the PATH for C preprocessor and import the pre-build CMSIS library. The following Digital Signal Processing (DSP) resources from Arm include DSP on Arm-based Cortex-M platforms and the optimized CMSIS-DSP library for building power-efficient and performant IoT applications. The CMSIS DSP library includes specialized algorithms for computing the FFT of real data sequences. The FFT is defined over complex data but in many applications the input is real. Real FFT algorithms take advantage of the symmetry properties of the FFT and have a speed advantage over complex algorithms of the same length.
