At DIII-D, plasmas are created and sustained using a real-time application known as the digital plasma control system (PCS). Due to the highly dynamic and unstable nature of magnetically confined plasmas in tokamak fusion experiments, real-time data acquisition and feedback control systems are in routine use with all major tokamaks. This paper describes the experiences of the DIII-D programming staff in adapting Linux based Intel computing hardware for use in real-time data acquisition and feedback control systems. International Nuclear Information System (INIS) Real-time data acquisition and feedback control using Linux Intel computers In this paper we explore approaches to reconfiguration of communication and computation resources in the T-CREST hard real-time multi-core platform. An interesting perspective on reconfigurable computing is to exploit run- time reconfiguration to support mode changes. In hard real-time systems, such average-case speed-up is not in itself relevant - it is the worst.

In addition, many hard real-time applications have multiple modes of operation, and each.In general-purpose computing multi-core platforms, hardware accelerators and reconfiguration are means to improve performance i.e., the average-case execution time of a software application. To support this focus, the platform must provide service guarantees for both communication and computation resources. case execution- time of tasks of an application that determines the systems ability to respond in time.

The characteristics of the user interface and its impact on application system design are assessed.Īpplication verification research of cloud computing technology in the field of real time aerospace experimentĪccording to the requirements of real-time, reliability and safety for aerospace experiment, the single center cloud computing technology application verification platform is constructed. Although SIFT represents a significant achievement in fault-tolerant system research it presents an unusual and restrictive interface to its users.
The SIFT computer system was designed to meet extremely high reliability requirements and to facilitate a formal proof of its correctness. The real-time capabilities of the SIFT computer system, a highly reliable multicomputer architecture developed to support the flight controls of a relaxed static stability aircraft, are discussed. With the same analysis techniqueĪn assessment of the real-time application capabilities of the SIFT computer system In this paper we present a novel analysis technique to compute conservative estimates of the required buffer capacities in such process networks. Soft real-time applications that process data streams can often be intuitively described as dataflow process networks.

We discuss the research and development of a prototype light detection and ranging (LiDAR) system via direct time of flight, which utilizes a single high-sensitivity photon-counting detector and fast- timing electronics to recover millimeter accuracy three-dimensional images in real time. The development of compressed sensing schemes for real-time computational imaging may have promising commercial applications for high-performance detectors, where the availability of focal plane arrays is expensive or otherwise limited. The availability of compact, low-cost, and high-speed MEMS-based spatial light modulators has generated widespread interest in alternative sampling strategies for imaging systems utilizing single-pixel detectors.
