Fixed Point implementation for a Microcontroller
Updated 29 Sep 2017
This example demonstrates an easy three click workflow to convert an ideal floating-point model of a fuel rate control algorithm to an embedded fixed point implementation using the Fixed-Point Tool.
It also demonstrates how you can use the Fixed-Point Tool to compress the Look up table memory footprint by choosing the right word length for your look up table and the breakpoints. You can further compare smaller word length and its impact on the numerical behavior of the algorithm in the Simulink data inspector. You can use the Fixed-Point Tool UI as well as the command line interface.
This will help you to take your motor and power control algorithms from floating point to efficient fixed point implementation on microcontrollers or on FPGAs.
