In order to cope with the environmental impacts onBluetooth data transmission diversity techniques wereexamined. A Bluetooth antenna diversity demonstratorwas developed. Extensive experimental investigationsdocumenting the significant improvements of ...

Abstract¿Providing up-to-date input to users' applications is an important data management problem for a distributed computing environment, where each data storage location and intermediate node may have specific data available, storage limitations, ...

Current FPGA soft processor systems use dedicated hardware modules or accelerators to speed up data-parallel applications. This work explores an alternative approach of using a soft vector processor as a general-purpose accelerator. The approach has ...

A new pipelined systolic array-based (PSA) architecture for matrix inversion is proposed. The pipelined systolic array (PSA) architecture is suitable for FPGA implementations as it efficiently uses available resources of an FPGA. It is scalable for different ...

Extensible processors allow addition of application-specific custom instructions to the core instruction set architecture. However, it is computationally expensive to automatically select the optimal set of custom instructions. Therefore, heuristic ...

Predicting the location of a mobile wireless user is an inherently interesting and challenging problem. Location prediction has received increasing interest over the past decade, driven by applications in location management, call admission control, ...

Most often, for a digital electronic device, the consumed power is indicated as an average value without explicitly expressing the functional conditions under which this power was measured. This is also true for microprocessors. For a large part of the ...

The authors present self-routing algorithms for realizing the class of linear permutations in various multistage networks such as Benes and 2n-stage shuffle-exchange. Linear permutations are useful in providing fast access of data arrays. In the first ...

Integrating wireless LAN (WLAN) techniques with the third generation cellular networks has become a promising way to improve the performance of wireless systems. As WLANs play an important role in such heterogeneous systems, the performance of WLANs ...

Computer architecture is about to undergo, if not another revolution, then a vigorous shaking-up. The major chip manufacturers have, for the time being, simply given up trying to make processors run faster. Instead, they have recently started shipping ...

Simulation models of a variety of computer architectures have been created using HASE, a Hierarchical Computer Architecture design and Simulation Environment. Some of these models were previously available as applets but using the models directly in ...

In this paper, we discuss efficient combinations of data migration processing and method migration processing in object database environments. When we have multiple servers and clients, it is practical to decide at a client which of the two ways should ...

Current processor allocation techniques for highly parallel systems have thus far been restricted to contiguous allocation strategies for which performance suffers significantly due to the inherent problem of fragmentation. We are investigating processor ...

We present a routability-driven top-down clustering technique for area and power reduction in clustered FPGAs. This technique is based on a multilevel partitioning approach. It leads to better device utilization, savings in area, and reduction in power ...

To meet the demand for higher performance, flexibility, and economy in today's state-of-the-art networks, an alternative to the ASICs that traditionally were used to implement packet-processing functions in hardware, called network processors (NPs), ...

This paper develops a complete auto-parallelisation approach for multiple-address space digital signal processors (DSPs). It combines a pointer conversion technique with a new modulo elimination transformation. This is followed by a combined parallelisation ...
