TI expands math libraries for low-power MCUs

Leveraging intelligent peripherals and optimised software to ease the burden of complex math instructions, Texas Instruments announced an expanded ecosystem of free and easy-to-use math libraries for its ultra-low power MSP430 microcontrollers (MCUs). Both MSPMATHLIB and IQmathLib software libraries are ideal for applications where performance and power are critical, such as orientation tracking.

It is now possible to use an inverse tangent function to measure pitch and roll angles in a fraction of the time with an MSP430 MCU, an accelerometer and IQmathLib. Other ideal applications for these optimised math software libraries include wireless sensor nodes, smart metering, heart rate monitors and any product with capacitive touch or graphics capabilities.

MSPMATHLIB is an accelerated library of floating point, scalar math functions that complete math-intensive operations in a fraction of the time, providing developers with up to 26 times the performance. The advanced math library helps 16bit MCUs execute code faster, which improves battery life in any math-intensive application. Developers can easily configure MSPMATHLIB software to improve performance on all MSP430F5xx, MSP430F6xx and MSP430FR5xx MCU series.

IQmathLib is now available for MSP430 MCU developers to help optimise 16bit and 32bit fixed point math. This math library provides the same benefits as MSPMATHLIB but can achieve up to 100 times the performance, while only limiting the flexibility of the data range. IQmathLib provides all the back-end functions necessary to increase performance without sacrificing power consumption. IQmathLib is available for all MSP430 MCU series.

A TI Design is available to display the performance and power capabilities of IQmathLib and allow developers to jumpstart system design on a variety of sensor fusion and asset monitoring applications. The reference design is an orientation tracker that processes several sensor inputs to monitor for tilts, drops or theft.

IQmathLib enables the MSP430 MCU to execute sample code quicker so the orientation tracker can go back to a low-power mode. This IQmathLib design includes several components from TI's MCU LaunchPad development ecosystem, such as the MSP430 Value Line LaunchPad, CircuitCo's Educational BoosterPack, and the new Fuel Tank BoosterPack from Element14 and TI.
