DALLAS, Nov. 3, 2010 /PRNewswire/ -- Delivering
floating-point benefits to developers using fixed-point
microcontrollers (MCUs), Texas Instruments Incorporated (TI) (NYSE:
TXN) today announced that its free IQmath Library now supports both
the 32-bit C2000 and Stellaris MCU platforms. TI's IQmath Library
is a proven, optimized collection of high-precision mathematical
functions that allows programmers to seamlessly port floating-point
algorithms into fixed-point code. Developers can use the software
to achieve execution speeds considerably faster than equivalent
code written in standard ANSI C language, which is important to
computationally intensive applications such as motor control,
digital power, security and human-machine interfaces. The IQmath
Library also significantly speeds development and addresses the
limitations of fixed-point math by eliminating time-consuming
scaling and saturation burdens. For more information, go to
www.ti.com/iqmath-pr-lp.
"We have used TI's IQmath with fixed-point C2000 MCUs in our
real-time motor control applications for more than five years, and
it has greatly simplified, sped and optimized our development,"
said Dr. Dal Ohm, president, Drivetech, Inc. "The correct range and
precision enabled by IQmath is critical in creating stable control
systems for the complex power electronics that I design, and the
software has also made it very easy to scale to the floating-point
C2000 devices."
IQmath Library features and benefits:
- Simplified porting from floating-point simulations/algorithms
to a fixed-point MCU
- Math library for fixed-point processors speeds computation of
floating-point values
- 45+ functions organized in easy-to-access categories, including
format conversion utilities, arithmetic functions, trigonometric
functions and mathematical functions
- Adjustable resolution and dynamic range allows optimization
based on application requirements
- Seamless code portability for scaling between fixed- and
floating-point MCUs
- Conversions from floating to fixed point are completed at the
compile stage, so CPU cycles are not used
Pricing and availability
IQmath software is free and available for download through
StellarisWare® software or C2000 controlSUITE™ software at
www.ti.com/iqmath-pr-lp. Fixed-point Stellaris MCUs start at
$1, and fixed- and floating-point
C2000 real-time control MCUs start at less than $2. Samples and orders can be placed at
www.ti.com/iqmath-buy-pr-lp.
