DSP Blockset

Boolean Support

Many DSP Blockset blocks accept or output logical signals. All such blocks support the Boolean data type at their appropriate ports:

• All block input ports that accept logical signals support the Boolean data type.
• The default data type of all outputs that are logical signals is Boolean. (You can change this default setting and disable Boolean support as described in a later section.)

Advantages of Using the Boolean Data Type

Using the Boolean data type rather than floating-point data types speeds up simulations and results in smaller, faster generated C code. (For more on generated code, see Code Generation Support.)
