چکیده

This article describes a class of reconfigurable computing system called online architectures. These architectures use an online algorithm to make run-time reconfiguration decisions that continually adapt the underlying architecture to match the application’s current computational demand. Online architectures have several potential advantages, including better resource utilization (reduced cost), faster execution, and reduced (static) power consumption. However, to realize these benefits, online architectures must balance the overhead (reconfiguration, profiling, and decision costs) against expected gains of reconfiguration. In this article, the basic foundation of online architecture is formulated, core challenges enumerated, and results reported based on a simple prototype and trace-driven simulations. These results suggest that the overhead is manageable and that a more comprehensive investigation is worthwhile.

Design and Experimental Study of a Combined Pneumatic Plot Seed-metering Device for Cotton

This study presents a combined pneumatic seed-metering device (SMD) that could not only fill, carry, and meter seeds, but also switch quickly between seed-metering and seed-cleaning modes, and clean seeds thoroughly and rapidly. The seed-filling, seed-carrying, and seed-metering modes of the SMD were analyzed based on a theoretical kinematic model. Furthermore, a three-factor, three-level ortho...

Design and fabrication of a prototype planar undulator

The main goal of this work is to get the fabrication technology of the insertion devices. A prototype undulator with the period of 48mm and the peak magnetic field of 0.75 T has been fabricated using NdFeB-SH35 magnets based on the cooperation between ILSF and NSTRI. The total magnet length is 483 mm and the number of periods is 8. The magnetic parameters of the undulator are determined in orde...

A Scalable Parallel Formulation of the Backpropagation Algorithm for Hypercubes and Related Architectures

In this paper, we present a new technique for mapping the backpropagation algorithm on hypercubes and related architectures. A key component of this technique is a network partitioning scheme which is called checkerboarding. Checkerboarding allows us to replace the all-to-all broadcast operation performed by the commonly used vertical network partitioning scheme, with operations that are much f...
