Sundance Multiprocessor’s latest low-cost embedded module accurately measures energy consumption and saves fault identification time

Sundance Multiprocessor Technology Ltd., a supplier and manufacturer of embedded modules, has launched Lynsyn Lite, a low-cost power measurement tool for the development of embedded and customized low-energy computing (CLEC) systems that require a high degree of energy efficiency.

Developed in collaboration with the Norwegian University of Science and Technology (NTNU), Lynsyn Lite overcomes the challenges of accurately measuring energy consumption. As compared to traditional power measurement equipment, this highly energy-efficient platform is built for complex image processing applications and significantly lowers the time consumption during detection of power issues.

Lynsyn Lite features three sensors that measure both current and voltage. The device has been designed to support application power of systems based on ARM Cortex A9, A53 and A57 cores. Because of this, there is no need to purchase a separate JTAG pod as it is a replacement for the Xilinx Platform Cable USB-II and can also be used as a JTAG programming device with the Xilinx Vivado tool suite and a remotely controlled current/voltage meter.

It connects over JTAG to sample the program counters of the system processors and then correlate the power measurements with the source code, therefore mapping consumption samples as per the application activity. A sampling frequency of up to 10kHz is used.

Lynsyn Lite is compatible with both Linux and Windows operating systems. It includes open source software that both samples and visualizes measurement results.

“High-performance embedded and customized low-energy computing systems require a high degree of energy efficiency, the development of which demands accurate measurement of energy consumption based on application behaviour,” said Flemming Christensen, Managing Director of Sundance Multiprocessor Technology. “Lynsyn Lite quickly, easily and accurately overcomes the challenges involved at a fraction of the cost of previous solutions. Designed to perform application power profiling primarily of systems based on ARM Cortex A cores, it can also be used as a generic power profiling tool.”
