As the product of the combination of edge computing and artificial intelligence, edge intelligence (EI) not only solves the problem of insufficient computing capacity of the end device, but also can provide users with various types of intelligent ...

To prolong battery life of mobile devices, image processing applications often exploit offloading techniques which run some or all of the computations on remote servers. Unfortunately, the existing offloading techniques do not consider the fact that data ...

Buildings account for nearly 40 percent of the total energy consumption in the United States. As a critical step toward smart cities, it is essential to intelligently manage and coordinate the building operations to improve the efficiency and ...

While several hardware mechanisms have been proposed to control the interaction between hardware threads in an SMT processor, few have addressed the issue of software-controllable SMT performance. The IBM POWER5 and POWER6 are the first high-performance ...

A classic optimization problem in network routing is to minimize C+D, where C is the maximum edge congestion and D is the maximum path length (also known as dilation). The problem of computing the optimal C^{\ast}+D^{\ast} is NP-complete even when ...

This paper proposes the use of microprocessor performance counters for online measurement of complete system power consumption. The approach takes advantage of the "trickle-down” effect of performance events in microprocessors. While it has been known ...

In many application areas, including control systems, careful management of system resources is key to providing the best application performance. Traditional control systems with multiple control loops statically allocate a fixed portion of the system ...

In 2000 we described a proposal for a logarithmic arithmetic unit, which we suggested would offer a faster, more accurate alternative to floating-point procedures. Would it in fact do so, and could it feasibly be integrated into a microprocessor so that ...

Power consumption is an important issue in the design of real-time embedded systems. As many embedded systems are powered by batteries, the goal is to extend the autonomy of the system as much as possible. To reduce power consumption, modern processors ...

Soft errors are changes in memory value caused by external radiation or electrical noise. Decreases in computing feature sizes and power usages and shorting the microcycle period enhance the influence of soft errors. Self-stabilizing systems are ...

Fair sharing of bandwidth remains an unresolved issue for distributed systems. In this paper, the users of a distributed LAN are modeled as selfish users with independence to choose their individual strategies. With these selfish users, the contention-...

Uniprocessor designs have always assumed worst-case operating conditions to set the operating clock frequency and, hence, performance. However, much more performance can be obtained under typical operating conditions through experimentation, but such ...

In this paper, a secure and anonymous conference call set-up scheme is proposed for a portable cellular mobile system. The proposed scheme uses an identity-based concept and enables a mobile unit and a base station to directly authenticate each other by ...

Compression of executable code in embedded microprocessor systems, used in the past mainly to reduce the memory footprint of embedded software, is gaining interest for the potential reduction in memory bus traffic and power consumption. We propose three ...

Abstract--In this paper, we present a novel stochastic model to study the performances of the two-phase dynamic locking in database systems with no-waiting policy. It is a general stochastic model to describe the database environment and transaction ...

Abstract--Caches have been used extensively to store the most popular/recent requested data to improve the user latency and reduce the network load. Recently, a more systematic approach to caching has been developed within the framework of Content ...

This paper describes nonideal properties of batteries and how these properties may impact power-performance trade offs in wearable computing. The first part of the paper details the characteristics of an ideal battery and how these characteristics are ...

Dynamic Power Management (DPM) is a design methodology aiming at reducing power consumption of electronic systems by performing selective shutdown of idle system resources. The effectiveness of a power management scheme depends critically on an accurate ...

Personal Number (PN) service or Follow-me service allows a user to access telecommunication services with any terminals (e.g., fixed telephones or mobile phones) in any locations within the service area. To provide this feature, the PN user needs to ...

The low cost and wide availability of networks of workstations have made them an attractive solution for high performance computing. However, while a network of workstations may be readily available, these workstations may be privately owned and the ...
