Data type optimization automatically iterates through various fixed-point configurations to choose the optimal heterogeneous data types while meeting tolerance constraints on the numerical behavior of your system. The optimization seeks to minimize an objective function, such as total bit width or total operator counts, using fixed-point data types for an efficient design.

You can optimize data types using thefxpoptfunction at the command line, or by using theOptimized Fixed-Point Conversionworkflow in the Fixed-Point Tool.
