Although many studies have demonstrated the benefits of reconfigurable computing, it has not yet penetrated the mainstream. One of the biggest unsolved problems is the management of the reconfigurable hardware in a multi-threaded environment. Most research in reconfigurable computing has assumed a single-threaded model, but this is unrealistic for personal(More)
Due to the ever-increasing complexity of VLSI designs and IC process technologies, the mismatch between a circuit fabricated on the wafer and the one designed in the layout tool grows ever larger. Therefore, characterizing and modeling process variations of interconnect geometry has become an integral part of analysis and optimization of modern VLSI(More)
Over the past few years, the realm of embedded systems has expanded to include a wide variety of products, ranging from digital cameras, to sensor networks, to medical imaging systems. Consequently, engineers strive to create ever smaller and faster products, many of which have stringent power requirements. Coupled with increasing pressure to decrease costs(More)
In this paper, we present a full-system reconfigurable computing simulation platform intended to promote innovative new research in reconfigurable computing. Currently, reconfigurable computing researchers frequently use tools such as simple trace-based simulators to provide performance estimates for their designs and methods. However, because the scope of(More)
The use of reconfigurable hardware to accelerate computing intensive part of the applications has long been shown to provide large execution speedups. However, the long configuration latency and the limited amount of reconfigurable hardware resources demands careful arbitration of those resources among the applications in the system. In past efforts, we(More)
preemption in multi-tasking operating systems. Multi-tasking, and by consequence, preemption, is key to effective CPU sharing. However, it is much more expensive to save and restore context data in reconfigurable hardware than it is in traditional software. The configuration and current state comprises a large amount of data, making the transfer a long and(More)
With continuous advances in radio-frequency (RF) mixed-signal very large scale integration (VLSI) technology, the creation of eddy currents in lossy multilayer substrates has made the already complicated interconnect analysis and modeling issue more challenging. To account for substrate losses, traditional electromagnetic methods are often computationally(More)
Evaluating the performance of reconfigurable computing applications in multi-tasking systems using simulation (as can be needed in early design-space exploration) faces several challenges. The complexity of full-system, cycle-accurate simulation prevents executing applications of any appreciable size to completion. One must sample only a portion of(More)
Although the benefits of software acceleration using reconfigurable logic have been demonstrated repeatedly, this style of computing has not yet penetrated the mainstream. One of the biggest unsolved problems is the management of the reconfigurable hardware in a multi-threaded environment. While most research in reconfigurable computing has assumed a(More)
Performance evaluation of hybrid (heterogeneous ISA) computing systems faces three major challenges: hybrid execution, multi-tasking, and system-level simulation variation. To evaluate system-level design decisions, a metric must encompass all forms of execution in a system, and incorporate any overheads introduced by hybrid execution. Differences in(More)
