    On the Capacity of Free-Space Optical Intensity Channels

    New upper and lower bounds are presented on the capacity of the free-space optical intensity channel. This channel is characterized by inputs that are nonnegative (representing the transmitted optical intensity) and by outputs that are corrupted by additive white Gaussian noise (because in free space the disturbances arise from many...

    A Flexible P2P Publish/subscribe Framework

    Nowadays, many structured P2P algorithms have been proposed frequently. Consequently, the P2P application developers need to learn different P2P API semantics. Developers will take additional efforts if they want to replace the underlying P2P networks of their P2P applications with other ones. Moreover, it is difficult for the developers to...

    Energy Efficient Intra-Task Dynamic Voltage Scaling for Realistic CPUs of Mobile Devices

    It is not energy efficient to run a CPU at full speed all the time for all kinds of tasks in mobile devices. This paper proposes two energy efficient intra-task Dynamic Voltage Scaling (DVS) algorithms for CPUs. There are three main contributions in this paper. Firstly, unlike the tedious derivation...

    Filtering of Unnecessary Branch Predictor Lookups for Low-Power Processor Architecture

    Efforts to reduce power consumption of processors have gained much attention recently. Dynamic branch predictor, including BTB, is exercised in every instruction cycle, yet branch instructions only constitute a small percentage of instructions during program execution. This paper proposes a novel method to collect the next branch distances of the...

    A Novel Approach to Comparison-Based Diagnosis for Hypercube-Like Systems

    Interconnection network has been an active research area for parallel and distributed computer systems. The diagnosability is one of the important issues in the reliability of interconnection networks. In this paper, a novel idea on system diagnosis called local diagnosability is presented. The concept of local diagnosability is strongly related...

    Event-Driven Dynamic Workload Scaling for Uniprocessor Real-Time Embedded Systems

    Many embedded systems are designed to take timely reactions to the occurrences of particular scenarios. For example, an automobile controlling system should simultaneously control cruising, traction, the brake system, and the engine. A real-time surveillance system in a shopping mall could track a number of moving people and evaluate pre-defined...

    Performance Evaluation of Inter-Processor Communication for an Embedded Heterogeneous Multi-Core Processor

    Embedded systems often use a heterogeneous multi-core processor to improve performance and energy efficiency. This multi-core processor is composed of a General Purpose Processor (GPP), which manages the program flow and I/O, and a Digital signal Processor (DSP), which processes mass data. An Inter-Processor Communication (IPC) mechanism is thus required...

    Efficient k-out-of-n Oblivious Transfer Schemes

    Oblivious transfer is an important cryptographic protocol in various security applications. For example, in on-line transactions, a k-out-of-n oblivious transfer scheme allows a buyer to privately choose k out of n digital goods from a merchant without learning information about other n-k goods. In this paper, the authors propose several...
