TIDM-FILTERING-SIGNALPROCESSING

Design files

Overview

This reference design showcases the performance of the low-energy accelerator (LEA) on MSP430™ FRAM microcontroller (MCUs) in performing advanced filtering and signal processing while maintaining ultra-low power on a 16-bit MCU. The LEA provides a boost of 13.8x over a traditional C implementation for a 256-point complex FFT. LEA also provides real-time FIR filtering performance at a high audio sampling rate of 20 kHz.

Features
  • Real-time FFT comparing non-accelerated to accelerated performance
  • Real-time FIR filtering with several pre-set filter coefficients
