    Due to the high computational complexity of discrete cosine transform (DCT) computation, prediction of zero quantized DCT (ZQDCT) coefficients has been extensively studied to reduce the computational complexity of DCT computation. In this letter, we propose a reconfigurable architecture to support ZQDCT computation. Twelve different modes of DCT computations including zonal coding, multiblock proc... View full abstract»

    This letter presents partition-oriented ERfair scheduler (POES), a low-overhead proportional fair scheduler for hard real-time multiprocessor embedded systems. POES achieves lower overheads using an online partitioning/merging mechanism that retains the optimal schedulability of a fully global scheduler by merging processor groups as resources become critical while using partitioning for fast sche...

    This letter presents the practical issues concerning late and insufficient verification of low-level software on hardware platforms developed by our industrial partner. To overcome these issues, we propose a coverification platform based on process algebra. The descriptions of hardware and software, and their interface are translated into a common process-algebraic platform, and formal verificatio... View full abstract»

    The need to improve nonvolatile memories reliability in embedded systems is a key design concern. We here propose a methodology, managed by the memory controller, that optimizes the data reliability at the physical level for critical data whereas exploiting the transaction performances for noncritical data. The reliability-performance tradeoff is obtained by partitioning the memory addressable spa... View full abstract»

  • Parallelism, Performance, and Energy-Efficiency Tradeoffs for In Situ Sensor Data Processing

    Publication Year: 2011, Page(s):16 - 19
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (688 KB) | HTML iconHTML

    The in situ processing of vast amounts of data, available intermittently in networks of sensors, motivates investigation of means for achieving high performance when required, but ultralow-power dissipation when idle. One approach is the use of embedded multiprocessor systems, leading to tradeoffs between parallelism, performance, energy-efficiency, and cost. To evaluate these tradeoffs, and to ga...

    The design and implementation of a lossless compression system for hyperspectral images on a processor-plus-field-programmable gate array (FPGA)-based embedded platform. Software execution time of compression algorithm was profiled first to conclude the decision of accelerating the most time consuming interband prediction module by hardware realization. Efficient algorithm to hardware mapping led ... View full abstract»

    We present a framework, OpenCLosE, for dynamic resource management and scheduling of applications written in open compute language (OpenCL) for heterogeneous multimedia and graphics platforms, such as those found in multimedia smartphones and automotive infotainment clusters. We describe the design of a resource manager and master scheduler for the OpenCLosE environment, that allows efficient real... View full abstract»

  • A Kleene Algebra of Tagged System Actors

    The tagged signal model (TSM) is a formal framework for modeling heterogeneous embedded systems. In the present work, we provide a representation of tagged systems using the semantics of Kleene algebra. Such an algebraic representation facilitates the usage of standard off-the-shelf theorem provers for reasoning about such systems for both behavioral verification through equivalence checking and p...

  • Managing Battery and Supercapacitor Resources for Real-Time Sporadic Workloads

    Cited by:  Papers (8)

    Batteries and supercapacitors are complementary: batteries have a high energy-to-weight ratio but are limited in the power levels they can support; supercapacitors can provide high levels of power while they have a much lower energy-to-weight ratio. A battery-supercapacitor duo can therefore prove useful in embedded systems serving sporadic, energy-intensive, tasks: the battery charges the capacit... View full abstract»

    Transactional memory is a mechanism of controlling access to shared resources in concurrent programs. Though originally implemented in hardware, software implementations of transactional memory are now available as library extensions in all major programming language. Lately, variants of software transactional memory (STM) with real-time support have been presented. The conflict detection policy u... View full abstract»

    Embedded learning applications in automobiles, surveillance, robotics, and defense are computationally intensive, and process large amounts of real-time data. Systems for such workloads have to balance stringent performance constraints within limited power budgets. High performance computer processing units (CPUs) and graphics processing units (GPUs) cannot be used in an embedded platform due to p... View full abstract»

    SystemC is a widely used electronic system-level (ESL) design language that can be used to model both hardware and software at different stages of system design. There has been a lot of research on behavior synthesis of hardware from SystemC, but relatively little work on synthesizing embedded software for SystemC designs. In this letter, we present an approach to automatic software synthesis from... View full abstract»
