Implementation of the FITA Fuzzy Inference System on the specific microcontroller platform

The paper describes basic approach to building a general purpose MISO-FITA (multiple inputs single output rule based system) fuzzy logic inference system. The system is based on STM32F4Discovery board with the ARM Cortex-M4 STM32F407VG microcontroller. The fuzzy engine of the system is based on simplified Mamdani’s fuzzy inference model. The performance of the fuzzy inference system, defined as a time to obtain an output crisp inference result, is comparable to hardware solutions. For proposed system it even takes 10 s.
