This research relates to the patent application tendency about the hardware platform of the intelligent robot among the robotics industry in which the market is more and more expanded. The patent about the hardware field of intelligent robot was analyzed from not only Korea but also U.S., Japanese and Europe which is called as the 3 pole of patent. By this research the government which supervises the nation's research policy can obtain the objective information of the industrial tendency, so it can establish the investment policy of national research and development. And the researchers can set up the research direction for evasion from patent infringement trouble by obtaining the patent application information. This also shows whether their research can be competitive or not.

In recent years, with the development of autonomous driving technology, high-performance artificial intelligence computing hardware platforms have been developed that can process multi-sensor data, object recognition, and vehicle control for autonomous vehicles. Most of these hardware platforms have been developed overseas, such as NVIDIA's DRIVE PX, Audi's zFAS, Intel GO, Mobile Eye's EyeQ, and BAIDU's Apollo Pilot. In Korea, however, ETRI's artificial intelligence computing platform has been developed. In this paper, we discuss the specifications, structure, performance, and development status centering on hardware platforms that support autonomous driving rather than the overall contents of autonomous driving technology.

This study proposes a hardware-in-the-loop simulation (HILS) system based on National Instruments' PXI platform to test power management and operation strategies for DC microgrids (MGs). The HILS system is developed based on the controller HIL prototype, which involves testing the controller board in hardware with a real-time simulation model of the plant in a real-time digital simulator. The system provides an economical and effective testing function for research on MG systems. The decentralized power management strategy based on the DC bus signaling method for DC MGs has been developed and implemented on the HILS platform. HILS results are determined to be similar to those of the off-line simulation in PSIM software.

This paper, presents an efficient hardware architecture of high performance SVC(Scalable Video Coding). This platform uses dedicated hardware architecture to improve its performance. The architecture was prototyped in Verilog HDL and synthesized using the Synopsys Design Compiler with a 65nm standard cell library. At a clock frequency of 266MHz, This platform contains 2,500,000 logic gates and 750,000 memory gates. The performance of the platform is indicated by 30 frames/s of the SVC encoder Full HD($1920{\times}1080$), HD($1280{\times}720$), and D1($720{\times}480$) at 266MHz.

In this paper, we developed a hardware and software platform of the real-time data logging system to verify radar FEM (Front-end Module) and signal-processing algorithms. We developed a hardware platform based on FPGA (Field Programmable Gate Array) and DSP (Digital Signal Processor) and implemented firmware software to verify the various FEMs. Moreover, we designed PC based software platform to control radar logging parameters and save radar data. The developed platform was verified using 24 GHz multiple channel FMCW (Frequency Modulated Continuous Wave) in an environment of stationary and moving targets of chamber room.

2012년 1월부터 공간정보 오픈플랫폼의 서비스가 시작된 이래로, 서비스가 늘어남에 따라 서비스 이용자 수와 시스템의 규모가 크게 증가하게 되었다. 그러나 이러한 오픈플랫폼 시스템이 가지고 있는 하드웨어 자원들이 어느 수준의 서비스를 처리할 수 있는지에 대한 자세한 분석 결과는 전혀 알 수 없었다. 이러한 이유로 특정 이슈와 더불어 서비스 이용자가 급증할 때마다 서비스를 처리하기 위하여 단순히 하드웨어 증설을 통해 일시적으로 서비스 지연 문제를 해결하여 왔다. 이에 본 연구에서는 현재 오픈플랫폼이 보유하고 있는 시스템 성능을 정확히 파악하여 향후 동일한 문제가 발생하지 않도록 근본적인 해결책을 제시하고자 한다. 구체적으로 본 연구에서는 NMON을 이용한 하드웨어 성능 분석과 nGrinder를 이용한 웹서비스 부하 테스트를 통해 오픈플랫폼이 현재 가지고 있는 정확한 시스템 성능을 파악하고, 이후 보다 나은 서비스를 제공할 수 있는 시스템으로 개선하기 위한 자원 재조정 방안을 제시하고자 한다.

임베디드 소프트웨어는 탑재될 하드웨어 아키텍처에 매우 의존적이기 때문에 플랫폼 특성을 고려한 소프트웨어 설계가 이루어져야 한다. 본 연구에서는 MPSoC(Multi Processor System On Chip)용 플랫폼에 탑재될 임베디드 소프트웨어의 PIM(Platform Independent Model)을 PSM(Platform Specific Model)에 매핑하기 위한 기법을 제안하고, 매핑 결과에 대한 시뮬레이션을 통해 매핑 기법의 유효성을 검사하였다. 제안하는 방법은 UML(Unified Modeling Language) 기반의 객체지향 모델로부터 태스크를 도출하여 이 기종의 하드웨어 컴포넌트로 구성된 MPSoC 플랫폼에 할당하기 위한 것으로써, 할당의 정확성 및 신속성과 소프트웨어 병렬성을 극대화 할 수 있는 장점을 제공한다.

This paper presents the construction results and design of the UNIST Reactor Innovation platform for small modular reactors as a versatile testbed for exploring innovative technologies. The platform uses simulant fluids to simulate the thermal-hydraulic behavior of a reference small modular reactor design, allowing for cost-effective design modifications. Scaling analysis results for single and two-phase natural circulation flows are outlined based on the three-level scaling methodology. The platform's capability to simulate natural circulation behavior was validated through performance calculations using the 1-D system thermal-hydraulic code-based calculation. The strategies for evaluating cutting-edge technologies, such as the integration of a solid oxide electrolysis cell for hydrogen production into a small modular reactor, are presented. To overcome experimental limitations, the hardware-in-the-loop technique is proposed as an alternative, enabling real-time simulation of physical phenomena that cannot be implemented within the experimental facility's hardware. Overall, the proposed versatile innovation platform is expected to provide valuable insights for advancing research in the field of small modular reactors and nuclear-based hydrogen production.
