DSP Blockset

Supported Data Types and How to Convert to Them

Note    All data type support applies to both simulation and Real-Time Workshop C code generation. All DSP Blockset blocks support single- and double-precision floating point.

The following table lists all data types supported by the DSP Blockset, and how to convert to these data types. To see which data types a particular block supports, check the "Supported Data Types" section of the block's online reference page.

Supported Data Types and How to Convert to Them 

Data Types Supported by DSP Blockset Blocks	Commands and Blocks for Converting Data Types	Comments
Double-precision floating point	double Data Type Conversion block	Simulink built-in data type supported by all DSP Blockset blocks.
Single-precision floating point	single Data Type Conversion block	Simulink built-in data type supported by all DSP Blockset blocks.
Boolean	boolean Data Type Conversion block	Simulink built-in data type. To learn more, see Boolean Support.
Integer (8-,16-, or 32-bits)	int8, int16, int32 Data Type Conversion block	Simulink built-in data type
Unsigned integer (8-,16-, or 32-bits)	uint8, uint16, uint32 Data Type Conversion block	Simulink built-in data type
Fixed-point data types (sfix, ufix, sint, uint, sfrac, ufrac)	Blocks in the Data Type library of the Fixed-Point Blockset Fixed-Point Blockset functions for conversions (listed in the online categorical function reference of Fixed-Point Blockset) Functions and GUIs for designing quantized filters with the Filter Design Toolbox (compatible with Filter Realization Wizard block)	To learn more about fixed-point support, see Fixed-Point Support.
Custom data types	See Correctly Defining Custom Data Types to learn about custom data types.
