Floating point unit demonstration on STM32 microcontrollers, software expansion for STM32Cube (AN4044)

This firmware package (X-CUBE-FPUDEMO) demonstrates the usage of the floating-point units (FPUs) available in the STM32 microcontrollers based on Cortex®-M4 and -M7 cores.It includes the implementation of the Julia-set and Mandelbrot-set algorithms to highlight the performances on the STM32 microcontrollers, but also to show the added value of the double-precision FPU on the STM32 microcontrollers based on Cortex®-M7 core.

Choosing Julia-set gives the user an indication of the performances of the STM32 microcontrollers based on Cortex®-M4 and -M7 cores.Choosing Mandelbrot-set gives the user an indication about the gain in precision of the double-precision FPU on the STM32 microcontrollers based on Cortex®-M7 core.

This application is developed with the STM32Cube embedded software. It uses the IAR: EWARM, the ARM®Keil®: MDK-ARM and the free AC6: SW4STM32 tool chains and it can be easily tailored for any other tool chain.
