IQmath bibliotek til C2000 og Stellaris MCU'er
TI’s frit tilgængelige IQmath bibliotek understøtter nu C2000 og Stellaris microcontrollere (in english).
Delivering floating-point benefits to developers using fixed-point microcontrollers (MCUs), Texas Instruments (TI) announces 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.
- 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, says 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.
IQmath software is free and available for download through StellarisWare® software or C2000 controlSUITE software at www.ti.com/iqmath-pr-lp.
