How MSP430FRx MCUs achieve higher performance [Copy link]

A solution for wirelessly monitoring the condition of a motor to determine if maintenance or replacement is needed. The concept is simple: it monitors vibration and sends a wireless notification if the motor begins to vibrate outside of normal range.

This design takes advantage of the fast write speeds and high endurance of FRAM – but with a higher level of complexity. To truly optimize the system, the spectral analysis of the vibration data needs to be run on the MSP430FR5969 MCU, minimizing the data that must be transmitted wirelessly. By leveraging an optimized math library, the MSP MCU can efficiently run a 4096-point sampling FFT at regular intervals to compare values over time.

If you need to perform complex math calculations in your application, use libraries to optimize execution speed, accuracy, and power consumption in compute-intensive real-time applications. The MSP-IQMATHLIB optimized software library for MSP MCUs helps you reduce your time to market by providing optimized fixed-point functions including addition, multiplication, sine, and logarithm. These functions can achieve more than 100 times the performance compared to using the standard math.h header file. Looking for a floating-point math library? MSPMATHLIB is also available and can improve performance by up to 26 times !
