Use floating-point multiplication to handle net slope corrections

Description

The Fixed-Point Designer™ software uses floating-point multiplication to perform net slope correction for floating-point to fixed-point casts.

Category: Math and Data Types

Settings

Default: Off

On

Use floating-point multiplication to perform net slope correction for floating-point to fixed-point casts.

Off

Use division to perform net slope correction for floating-point to fixed-point casts.

Tips

• This optimization affects both simulation and code generation.

• When converting from floating point to fixed point, if the net slope is not a power of two, slope correction using division improves precision. For some processors, use of multiplication improves code efficiency.

Dependencies

• This parameter requires a Fixed-Point Designer license.
