DSP System Toolbox
You can use DSP System Toolbox with Fixed-Point Designer to model fixed-point signal processing algorithms and analyze the effects of quantization on system behavior and performance.
Fixed-point support in the system toolbox includes:
You can configure System objects™ and blocks in the system toolbox for fixed-Point modes of operation, enabling you to perform design tradeoff analyses by running simulations with different word lengths, scaling, overflow handling, and rounding method choices before you commit to hardware.
Fixed-point modes are supported for several DSP algorithms, including:
In Simulink, DSP System Toolbox automates the configuration of blocks for fixed-point operation. For example:
Filter design functions in DSP System Toolbox enable you to design floating-point filters that can be easily converted to fixed-point data types with Fixed-Point Toolbox. This design flow simplifies the design of fixed-point filters and lets you easily analyze quantization effects.
Using DSP System Toolbox with MATLAB Coder and Simulink Coder, you can generate C code from your algorithms and system models. The generated code can be used for verification, rapid prototyping, and implementation of your system during the product development process.
Using DSP System Toolbox with Filter Design HDL Coder™, you can generate HDL code from digital filter designs. In Simulink, DSP System Toolbox blocks provide support for HDL code generation when used with HDL Coder™.
