Lynsyn Lite: Доступное измерение мощности для Energy-Efficient Embedded Systems

Sundance Multiprocessor Technology представила Lynsyn Lite — cost-effective power-measurement solution tailored для embedded и customized low-energy computing (CLEC) systems demanding exceptional energy efficiency. Lynsyn Lite delivers precise application-level energy readings, simplifying traditionally tedious process pinpointing power-related bottlenecks compared to conventional laboratory-grade equipment.

Происхождение и коммерциализация

Foundational Lynsyn technology originates from Norwegian University of Science and Technology (NTNU) developed under EU TULIPP project — aimed to create high-performance energy-efficient reference platform для advanced image-processing applications. NTNU core innovation стала backbone Lynsyn Lite.

Supported by technology-transfer funds from TETRAMAX, Horizon 2020 hub для digitizing European industries в customized low-energy computing, NTNU collaborated с Sundance Multiprocessor Technology — another key TULIPP partner — to commercialise platform. In 2018, NTNU received Technology Transfer Award от HiPEAC, EU-funded Network of Excellence, recognising significance core Lynsyn technology.

Как это работает

Lynsyn Lite captures power consumption individual code sections в embedded и CLEC systems. Connecting over JTAG, it samples program counters non-intrusively и aligns resulting power data с source code — clear map energy usage per application action. Device supports sampling rate up to 10 kHz.

Сенсоры и совместимость

Lynsyn Lite incorporates three sensors simultaneously measuring current и voltage. Optimised для ARM Cortex A9, A53, A57 cores, board eliminates need separate JTAG pod replacing Xilinx Platform Cable USB-II. Может также serve as generic USB JTAG programmer для Xilinx Vivado и as remotely controlled current/voltage meter via USB. Compatible с both Linux и Windows, platform ships с open-source software sampling и visualising measurement data.

Key Features

• Detailed, accurate power profiling для each source-code segment.
• Three sensors для simultaneous current и voltage measurement.
• Program-counter sampling over JTAG to correlate power с code.
• Maximum sampling frequency 10 kHz.
• Supported ARM Cortex A cores: A9, A53, A57.
• Acts as remotely controlled current/voltage meter.
• Functions as generic USB JTAG programmer для Xilinx Vivado.
• Includes open-source sampling и visualisation software.

Lynsyn Lite will be distributed by Sundance under license from NTNU. Priced at US$125, £85, or €99 — one-fifth cost original Lynsyn board developed для TULIPP project.
