Due to its potential to greatly accelerate a wide variety of applications, reconfigurable computing has become a subject of a great deal of research. Its key feature is the ability to perform computations in hardware to increase performance, while retaining much of the flexibility of a software solution. In this survey, we explore the hardware aspects of(More)
By strictly separating reconfigurable logic from the host processor, current custom computing systems suffer from a significant communication bottleneck. In this paper, we describe Chimaera, a system that overcomes the communication bottleneck by integrating reconfigurable logic into the host processor itself. With direct access to the host processor’s(More)
Datacenter workloads demand high computational capabilities, flexibility, power efficiency, and low cost. It is challenging to improve all of these factors simultaneously. To advance datacenter capabilities beyond what commodity server designs can provide, we designed and built a composable, reconfigurable hardware fabric based on field programmable gate(More)
<italic>Reconfigurable hardware has the potential for significant performance improvements by providing support for application-specific operations. We report our experience with Chimaera, a prototype system that integrates a small and fast reconfigurable functional unit (RFU) into the pipeline of an aggressive, dynamically-scheduled superscalar processor.(More)
Logic partitioning is an important issue in VLSI CAD, and has been an active area of research for at least the last 25 years. Numerous approaches have been developed and many different techniques have been combined for a wide range of applications. In this paper, we examine many of the existing techniques for logic bipartitioning and present a methodology(More)
Asynchronous design has been an active area of research since at least the mid 1950's, but has yet to achieve widespread use. We examine the benefits and problems inherent in asynchronous computations, and in some of the more notable design methodologies. These include Huffman asynchronous circuits, burst-mode circuits, micropipelines, template-based and(More)
FPGA-based reprogrammable systems are revolutionizing some forms of computation and digital logic. As a logic emulation system they provide orders of magnitude speedup over software simulation. As a custom-computing machine they achieve the highest performance implementation for many types of applications. As a multi-mode system they yield significant(More)
Welcome to the special issue on field programmable gate arrays (FPGAs). FPGAs are becoming an increasingly important part of embedded systems, as the collection of papers in this issue illustrates. " An overview of reconfigurable hardware in embedded systems " provides a comprehensive overview of the state-of-the-art use of reconfigurable hardware in(More)
One of the major overheads for reconfigurable computing is the time it takes to reconfigure the devices in the system. This overhead limits the speedup possible in this paradigm. In this paper we explore configuration prefetching techniques for reducing this overhead. By overlapping the configuration loadings with the computation on the host processor the(More)
Field-programmable gate arrays (FPGAs) are becoming an increasingly important implementation medium for digital logic. One of the most important keys to using FPGAs effectively is a complete, automated software system for mapping onto the FPGA architecture. Unfortunately, many of the tools necessary require different techniques than traditional circuit(More)
