This study explores how teachers can enhance L2 instruction using a specialized corpus with a popular custom search engine from Google. With a focus on the learners' lexicogrammatical performance, a corpus-based system consisting of a database of genreand discipline-specific texts and a companion search engine are developed for an undergraduate L2 writing course. Using digital video technology,...

H ighly specialized embedded computer systems abound, and workloads for computing devices are rapidly changing. General– purpose processors are struggling to efficiently meet these applications’ disparate needs, and custom hardware is rarely feasible. The time is ripe for reconfigurable computing, which combines the flexibility of general-purpose processors with the efficiency of custom hardwar...

The Advanced Encryption Standard is used in many embedded devices to provide security. In the last years, several researchers have proposed to enhance general-purpose processors with custom instructions to increase the efficiency of cryptographic algorithms. In this work we have evaluated the impact of such instruction set extensions on the implementation security of AES. We have compared sever...

Reconfigurable instruction set processors provide the possibility of tailor the instruction set of a CPU to a particular application. While this customization process could be performed during runtime in order to adapt the CPU to the currently executed workload, this use case has been hardly investigated. In this paper, we study the feasibility of moving the customization process to runtime and...

The flexible MIPS soft processor architecture borrows selected technologies from highperformance computing to deliver a modular, highly customizable CPU targeted towards FPGA implementations for embedded systems; the objective is to provide a more flexible architectural alternative to coprocessor-based solutions. The processor performs out-of-order execution on parallel functional units, it del...

——We propose a technique to localize computation in Instruction Set Extensions (ISEs) that are clocked at very high speed with respect to the processor. In order to save power, data to and from Custom Instruction Units (CIUs) is synchronized via an optical signal that is detected through a Single-Photon Avalanche Diode (SPAD) capable of timing uncertainties as low as 50 ps. The CIUs comprise a ...

Reconfigurable computing (RC) is becoming increasingly popular as it bears the promise of combining the flexibility of software with the performance of hardware. Although the huge reconfiguration latency of the available FPGA platforms is a well-known shortcoming of the current Field-programmable Custom Computing Machines (FCCMs), little research in instruction scheduling has been undertaken to...

After lower-extremity orthopedic trauma and surgery, patients are often advised to restrict weight bearing on the affected limb. Conventional training methods are not effective at enabling patients to comply with recommendations for partial weight bearing. The current study assessed a novel method of using real-time haptic (vibratory/vibrotactile) biofeedback to improve compliance with instruct...
