The TIDM-02003 design also makes efficient use of the LEA available in the MSP430FR6043 MCU.
The LEA is a 16-bit hardware engine designed to perform signal processing, matrix multiplications, and other operations that involve vector-based signal processing, such as FIR, IIR, and FFT, without CPU intervention. Efficient use of this module can result in improvements of up to 36.4 times for typical math intensive operations.
The LEA is used by the Ultrasonic Sensing Flow Metering Library to accelerate all vector operations in its proprietary algorithms. The LEA not only reduces the processing time of many operations, but LEA also allows the CPU to go into a low-power state.
