DSP Blockset

Data Type Support

All DSP Blockset blocks support single- and double-precision floating-point data types during both simulation and Real-Time Workshop C code generation. Many blocks also support fixed-point and Boolean data types. The following table lists all data types supported by the DSP Blockset and which block to use when converting between data types. To see which data types a particular block supports, check the "Supported Data Types" section of the block's reference page.

Supported Data Types 

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	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 data types in the DSP Blockset, see Fixed-Point Support.
Custom data types	See Correctly Defining Custom Data Types to learn about custom data types.
