Use division to perform parameter optimization for fixed-point net slope computation with Fixed-Point Designer™. You can perform net slope computation using a rational approximation of the net slope. This results in an integer multiplication and/or division when simplicity and accuracy conditions are met, and this optimization can improve numerical accuracy and lead to more efficient code generation.

Fixed-Point Designer™ provides data types and tools for developing fixed-point algorithms in MATLAB® code, Simulink® models, and Stateflow® charts. It automatically proposes fixed-point data types and attributes such as word length. You can also specify attributes such as rounding mode and overflow action manually. You can perform accelerated bit-true simulations to observe the impact of limited range and precision.

Fixed-Point Designer lets you convert floating-point algorithms to fixed point. You can create and optimize fixed-point data types that meet your numerical accuracy requirements and target hardware constraints. You can simulate your design and analyze the results to obtain range information. Fixed-Point Designer uses this information to recommend word lengths and scalings for your fixed-point algorithm and enable you to compare fixed-point results with floating-point baselines.

Fixed-Point Designer supports C, HDL, and PLC code generation.
