Three researchers from Fujitsu Laboratories Ltd. and Fujitsu Laboratories of America, Inc. who studied the high-speed data transmission circuits for high-performance ICT systems, have won the Fiscal 2016 Commendation for Science and Technology Prize (Research Category), which was awarded by the Minister of Education, Culture, Sports, Science and Technology. The award ceremony was held on Wednesday, April 20th at the auditorium of the Ministry of Education, Culture, Sports, Science and Technology.
The Ministry of Education, Culture, Sports, Science and Technology (MEXT) commends individuals for their important achievements in science and technology R&D and their promotion of science and technology understanding. The awards are aimed at motivating researchers and helping to raise the level of Japan's science and technology. Research category recognizes people who have had highly creative research achievements or inventions with the potential to advance science and technology in Japan.
Modern servers and supercomputers use large-scale parallel architecture in which numerous processors are connected to process big data and compute massive scientific calculations. Maximizing the performance of these systems requires not only that individual processors run fast but also that the data be moved quickly between them. In the past, data transfer speeds between processors, either in the form of electrical or optical signals, have been limited to 20 Gbps (gigabits per second), due to significant waveform distortions. Another problem has been that higher transmission speeds have required more power.
This research successfully developed an equalizer circuit that compensates for distortions of the electric signals in low frequency as well as high frequency, and also a control circuit that automatically adjusts the compensation for each of several thousand signal lines in a system. In addition, this research produced a circuit that drives optical modulators at high speed and in low power for optical transmission systems.
This research has enabled high-speed electrical and optical signal transmission at 25 Gbps or higher in low power. It also supports large-scale systems with numerous signal lines. These results will contribute to building higher-performance systems used for big data and scientific calculations, and their reduced power demands will help lighten environmental footprints, including reducing CO2 emissions.
