Fixed-Point Designer enables you to specify all the fixed-point properties of your MATLAB code, Simulink models, and Stateflow charts. It provides full control of signedness, word length, and scaling. It supports application-specific word lengths from 1 bit to at least 128 bits. Binary-point scaling and arbitrary slope and bias scaling needed by sensors and actuators are also supported. You can control the details of the math, such as how to deal with rounding and overflow.
Fixed-Point Designer provides a large number of functions such as math and bitwise operations, array and matrix operators, CORDIC implementations, and trigonometric functions to support fixed-point computation.
The designer lets you control the fixed-point arithmetic. The fixed-point variables can either share a single set of arithmetic attributes or have their own attached arithmetic attributes.
