Communication between independently-clocked digital subsystems typically involves a nite probability of synchronization failure whose minimization introduces delays and consequent performance costs. This paper explores a technique that eliminates both the inherent unreliability of such communication and the performance overhead it implies. Our approach maintains a known phase relationship betwe...

For example, a standard definition video of 100GB+ costs roughly $252 per year to store and transmit via a cloud service such as Windows Azure. The cost could run into hundreds of thousands of dollars when hours of videos or thousands of uncompressed images in terabytes are stored. The transmission cost and time of such uncompressed data is additional overhead, since it requires gigabytes of ba...

This paper proposes a customized Activity-Based Costing system for companies engaged in e-commerce. The system is intended to more effectively track overhead costs particular to e-commerce. A case study of a Business-toCustomer (B2C) company is used to illustrate the process of system conception and implementation, and ongoing cost analysis. Finally, this paper examines several possible benefit...

Dominant players in a number of industries have pursued policies that may once have been effective, but that now make their markets attractive targets for new entrants. The strategies of new entrants rely on lower overhead costs, new technologies, and alternative distribution channels, and the active targeting of profitable customers. Dominant firms will struggle to respond to the threats, and ...

Troubleshooting is the task of fixing an abnormally behaving system. Many troubleshooting algorithms employ a diagnosis engine that returns a set of diagnoses Ω and their likelihoods (p(·)), where a diagnosis ω ∈ Ω is a set of components that may have been faulty and its likelihood p(ω) is the probability that ω is all the faulty components in the system. The Batch Repair Problem (BRP) is a rec...

Improving testability during the early stages of High-Level Synthesis (HLS) has several benefits, including reduced test hardware overhead, reduced test costs, reduced design iteration, and significant improved fault coverage. In this paper, we present a novel register allocation method, which is based on weighted graph coloring algorithm, targeting testability improvement for digital circuits....

Abstract— Chip Multiprocessors (CMPs) combine multiple cores on a single die, typically with private level-one caches and a shared level-two cache. The gap between processor and memory speed is alleviated primarily by using caches. However, the increasing number of cores on a single chip increases the demand on a critical resource: the shared L2 cache capacity. In this dissertation work , a los...

Activity-based costing (ABC) system more precisely allocates the overhead costs to cost objects (products, services or customers) than traditional costing systems. In ABC, resources are consumed by the activities, and multiple cost drivers are used to allocate the costs of activities to the products. The selection of activity and cost drivers is then highly significant. Using too few cost drive...

Recently, consolidation on virtual servers has gone from a small market to a massive industry migration which is affecting businesses across different kinds of companies. Virtualization can be useful to help IT organizations to reduce complexity and costs with management, ownership, and energy consumption, providing a flexible environment for the execution of IT services. In this context, under...

Both hardware and software prefetching have been shown to be eeective in tolerating the large memory latencies inherent in shared-memory multiprocessors; however, both types of prefetching have their shortcomings. In this paper, we propose an integrated hardware/software prefetching method that uses simple hardware that can handle most data accesses and software prefetching for the few remainin...
