MSP430™ MCU Low-Energy Accelerator (LEA) Performance and Energy Saving GUI




The low-energy accelerator (LEA) Performance and Energy Saving GUI, visually demonstrates the immediate benefit the LEA module integrated in some MSP430 microcontrollers (MCUs) can provide when performing vector-based signal processing operations. The tool allows users to quickly select an operation and test its performance in real-time on the MSP430FR5994 LaunchPad™ development kit. In addition, this tool takes advantage of MSP EnergyTrace™ technology to capture power data during function execution on the MCU. The operation is executed using both LEA and the CPU for a quick comparison of performance.

  • Quickly compare CPU and LEA performance
  • Visualize average power and number of execution cycles
  • Select between six vector-based signal processing operations
  • Customize operation length and order to best represent your application
