ISOCC 2017 is held with a theme of "SoC for Intelligent ICT". Recent IoT trend heavily depends on small things with various sensing capabilities, a certain level of intelligence, seamless wireless connectivity, ultra-low power consumption and sometimes batteryless operation. Such small intelligent things cannot be realized without a semiconductor system on a chip or SoC. Intelligent SoC senses and aggregates wanted information from outside, processes them to a desired way, and create values for humans. It can be applied to human wellness, robot industry, bio/medical health, and automotive, automated factory, and so much more. In this conference, we try to open a forum to discuss on key issues and hurdles to realize the intelligent SoCs and see what the future SoC will look like. We welcome all the researchers and colleagues from industries, academia, and research institutes to ISOCC 2017 to make this conference a valuable, enthusiastic, insightful, and enjoyable academic event in Korea.
