Modeling Fixed-Point Designs
Simulink Fixed Point enables you to specify all the fixed-point data type properties of your design data, including the number of bits, whether the data is signed or unsigned, and how it will be scaled. You can then instrument your model with fixed-point information. For example, word sizes from 1 to 128 bits are supported, and scaling can be controlled by either binary point location or slope and bias scaling. You can control the details of the math, such as how rounding and overflow will be dealt with. You can also control and display data types for block inputs, outputs, accumulators, and parameters.
A 10-bit receiver for an ultra wideband wireless communications system, modeled in Simulink and DSP System Toolbox. Simulink Fixed Point enables you to use fixed-point simulation to study the effects of limited range and precision on the receiver’s performance.
