Outcome from one year of domestic CPU core development project: Success potential verified with commercialization

In May 3, Consortium of Semiconductor Advanced Research (COSAR) held a domestic CPU core road show to look back on last one year of relevant government project. Yong-Ho Song, Leader of Intelligent Semiconductor Promotion Project Team, said that “the project invests KRW 1 billion each on six to seven Korean fabless companies for three years, during the period from 2015 to 2017. So far, some products have achieved commercialization despite difficult processes.”

The domestic CPU core road show introduced Core-A from Dynalith Systems, emCore from Advanced Digital Chips (Adchips), Aldebaran from Electronics and Telecommunications Research Institute (ETRI), MENSA core from Korea Electronic Technology Institute (KETI), etc.

Core-A from Dynalith Systems, optimized for small quantity batch production
Core-A is a soft-core product which is provided as RTL code and synthesized with logic synthesizer. Companies can use it without introduction cost or royalty through a relatively simple procedure such as technical agreement. Dynalith Systems claims that its performance is comparable to that of ARM9.

The company explains that “Core-A processor is suitable for applications where control function is more dominant than data processing. Core-A can be utilized as either a main processor or as a coprocessor and can be applied to FPGA design, making it suitable for small quantity batch production.”

emCore from Adchips, competing with overseas CPU cores

emCore from Adchips uses EISC (Extendable Instruction Set Computer) structure, which has been evaluated to have both simplicity of RISC and expandability of CISC. With development of ISA for the second-generation CPU core using its emCore, Adchips plans to enter ultra-light CPU market for IoT wearable devices and high-performance mobile CPU core market.

▲A drone using Empress processor was demonstrated. Empress is one of 32-bit emCore series from Adchips.

Adchips plans to establish SoC platform so that its emCore can be used appropriately depending on industry characteristics and develop low-end and middle-end emCore series aiming at such markets as IoT, wearable, smart consumer electronics and automotive applications.

Paradigm shift enabled by ion channel-based pressure sensor

A research team led by professor Chang-Soo Han of Korea University developed an ultra-sensitive soft pressure sensor which replicates ‘human skin’s sensory organs’ to their cell level. The sensor also consumes very low power or no power at all. Concerned parties in the Ministry of Science, ICT and Future Planning and the research project explained that the research is meaningful in that “it resulted in a new form of sensor completely departed from existing concept, which can be applied to various industrial fields where power consumption is an important concern, such as IoT, machinery, electronics, energy, environment, etc. It is also expected to become a core source technology to create a variety of new concept sensors including sensors imitating animal’s sensory organs.”

Why have Google’s autonomous cars run through 3.85 million km for road test?

“Google’s patents deal with software design ability regarding AI, machine learning (ML) and deep learning (DL), which are core factors of autonomous cars, as well as real situations during road tests, coping methods and learning.” Dr. Won-Yong Cha, Korea’s representative futurologist and director of ASPECT, explains thus in his recently-published book ‘Focused analysis of Google’s AI type autonomous vehicle patents.’ Total driving test distance that Google’s autonomous cars have covered to acquire relevant patents is 3.85 million kilometers (2,408,597 miles), among which distance driven in autonomous mode is 2.27 million kilometers. This accounts for around 60% of total distance and Google increased the figure up to 80% last year.

Patent applications for disaster response robot clearly on the rise

Interest in disaster response robots which can be deployed to the rescue of human lives or disaster recovery in place of human is increasing. Young-Ho Kwon, Director of Robot Automation Screening, KIPO, said that “development of disaster response robot technology is urgently demanded with frequency of natural disasters increasing globally.”
