Fixed-Point Blockset

Blocks Grouped by Category

The Fixed-Point Blockset blocks are grouped into the following categories based on usage.

Math Blocks
FixPt Absolute Value	Output the absolute value of the input.
FixPt Constant	Generate a constant value.
FixPt Dot Product	Generate the dot product.
FixPt Gain	Multiply the input by a constant.
FixPt Matrix Gain	Multiply the input by a constant matrix.
FixPt MinMax	Output the minimum or maximum input value.
FixPt Product	Multiply or divide inputs.
FixPt Sign	Indicate the sign of the input.
FixPt Sum	Add or subtract inputs.
FixPt Unary Minus	Negate the input.

Conversion Blocks
FixPt Conversion	Convert from one Fixed-Point Blockset data type to another.
FixPt Conversion Inherited	Convert from one Fixed-Point Blockset data type to another, and inherit the data type and scaling.
FixPt Data Type Propagation	Configure the data type and scaling of the propagated signal based on information from the reference signals.
FixPt Gateway In	Convert a Simulink data type to a Fixed-Point Blockset data type.
FixPt Gateway In Inherited	Convert a Simulink data type to a Fixed-Point Blockset data type, and inherit the data type and scaling.
