The permanent magnet synchronous motor (PMSM) supplied by an inverter plays key roles in the critical application. Therefore, many efforts have been paid to the fault tolerant of the PMSM drive system to ensure the system continue operate in the postfault situation. Fault tolerant include fault detection and fault diagnosis> remedial action combinationing of hardware and software reconfigurations...
Fault attack becomes a serious threat to system security and requires to be evaluated in the design stage. Existing methods usually ignore the intrinsic uncertainty in attack process and suffer from low scalability. In this paper, we develop a general framework to evaluate system vulnerability against fault attack. A holistic model for fault injection is incorporated to capture the probabilistic nature...
Image scaling is a fundamental algorithm used in a large range of digital image applications. In this paper, we propose an efficient VLSI architecture for a novel edge-directed linear interpolation algorithm. Our VLSI design is implemented using high level synthesis (HLS) tool, which generates RTL modules from C/C++ functions. HLS provides significantly improved design productivity compared to the...
Aggressive voltage and frequency scaling are widely utilized to exploit the design margin introduced by the process, voltage and environment variations. However, scaling beyond the critical voltage or frequency results to numerous timing errors, and hence unacceptable output quality. In this paper, a computation-skip (CS) scheme is proposed for recursive digital signal processors with a fixed cycles...
Video compression plays an important role in mobile applications, because more and more people use video to communicate with each other (like video call etc). However, the resources (energy, memory etc.) on mobile devices are limited, thus how to achieve a high coding performance in these devices becomes a big challenge. The recent standards such as H.264, HEVC and audio video coding standard (AVS)...
With acceleration of the population aging process, the people pay more and more attention on the development of the robot for the elderly. On the basis of technical research and development of service robot positioning technology in recent years, the paper designed the system of the robot for the elderly based on star positioning. The system used ARM9 processor S3C2440 as the core, equipped with IPC...
