Measurement tool helps build energy-efficient embedded systems
Sundance Multiprocessor Technology has launched Lynsyn Lite, a low-cost power measurement tool for energy-efficient embedded and customized low-energy computing (CLEC) systems.

Lynsyn Lite has been developed to accurately measure the target system’s energy consumption depending on the application behaviour. It helps to reduce the time taken to find the root causes of power issues compared to laboratory-grade power measurement equipment.

The core technology behind Lynsyn was developed by the Norwegian University of Science and Technology (NTNU) as part of the EU’s recently completed TULIPP project, to overcome the challenges of accurately measuring energy consumption in the development of the project’s high performance, energy-efficient reference platform.

Developed with technology transfer funding from TETRAMAX, Lynsyn Lite was developed by NTNU with Sundance Multiprocessor Technology, also a prominent member of the TULIPP consortium. Lynsyn Lite provides a cost-efficient implementation of the core Lynsyn technology.

Lynsyn Lite measures the power usage of individual sections of source code deployed in embedded and CLEC systems. It used a JTAG connection to sample the program counters of the system processors and correlate the power measurements with the source code, mapping consumption samples to application actions. A sampling frequency of up to 10kHz is used.

Lynsyn Lite includes three sensors that measure both current and voltage and, although it has been designed to support application power profiling primarily of systems based on ARM Cortex A9, A53 and A57 cores, there is no need to purchase a separate JTAG pod as it is a replacement for the Xilinx Platform Cable USB-II and can, therefore, also be used as a generic JTAG programming device with the Xilinx Vivado tool suite and a remotely controlled current/voltage meter over USB. Lynsyn Lite is compatible with both Linux and Windows and includes open-source software that both samples and visualizes measurement results. Lynsyn Lite will be sold by Sundance under license from NTNU. Priced at US$125, £85 or €99.
