IQMath: Develop in Easy-to-Use
Floating Point on a Cost-
Effective, Fixed-Point Machine
Control algorithms typically start life in a
floating-point format. Until now, the conversion
of such algorithms to run on a
fixed-point machine was laborious and
time consuming. TI’s C28x IQMath
Library makes this task easier, faster and
enables:
• Seamless portability of code between
fixed- and floating-point devices
• One source code set for simulation vs.
target device
• Numerical resolution adjustability
based on application requirement
• Numerical accuracy without sacrificing
time and cycles
• Rapid conversion/porting and implementation
of algorithms
