Abstract: This paper describes about dynamic reconfiguration to
miniaturize arithmetic circuits in general-purpose processor. Dynamic
reconfiguration is a technique to realize required functions by
changing hardware construction during operation. The proposed
arithmetic circuit performs floating-point arithmetic which is
frequently used in science and technology. The data format is
floating-point based on IEEE754. The proposed circuit is designed
using VHDL, and verified the correct operation by simulations and
experiments.
Abstract: In the last years, the computers have increased their capacity of calculus and networks, for the interconnection of these machines. The networks have been improved until obtaining the actual high rates of data transferring. The programs that nowadays try to take advantage of these new technologies cannot be written using the traditional techniques of programming, since most of the algorithms were designed for being executed in an only processor,in a nonconcurrent form instead of being executed concurrently ina set of processors working and communicating through a network.This paper aims to present the ongoing development of a new system for the reconfiguration of grouping of computers, taking into account these new technologies.
Abstract: This paper proposes an architecture of dynamically
reconfigurable arithmetic circuit. Dynamic reconfiguration is a
technique to realize required functions by changing hardware
construction during operations. The proposed circuit is based on a
complex number multiply-accumulation circuit which is used
frequently in the field of digital signal processing. In addition, the
proposed circuit performs real number double precision arithmetic
operations. The data formats are single and double precision floating
point number based on IEEE754. The proposed circuit is designed
using VHDL, and verified the correct operation by simulations and
experiments.
Abstract: Software projects are very dynamic and require
recurring adjustments of their project plans. These settings can be
understood as reconfigurations in the schedule, in the resources
allocation and other design elements. Yet, during the planning and
execution of a software project, the integration of specific activities
in the projects with the activities that take part in the organization-s
common activity flow should be considered. This article presents the
results from a systematic review of aspects related to software
projects- dynamic reconfiguration emphasizing the integration of
project management with the organizational flows. A series of studies
was analyzed from the year 2000 to the present. The results of this
work show that there is a diversity of techniques and strategies for
dynamic reconfiguration of software projects-. However, few
approaches consider the integration of software project activities with
the activities that take part in the organization-s common workflow.
