	Reconfigurable Computing at PARL (Site not responding. Last check: 2007-10-14)
		Reconfigurable Computing (RC) is an area of computer systems architecture that studies the use of reconfigurable logic as a computational device to be used along with other computing structures such as integer ALUs, memory management units, floating-point multipliers, disk controlers, and network interfaces.
		RC is also known as ``Custom Computing Machines'' (CCMs) or just ``Configurable Computing.'' By reconfigurable logic, we are talking about programming the hardware at the gate-level rather than at the machine instruction level.
		The Clemson University Reconfigurable Computing effort is housed in the Parallel Architecture Research Laboratory (PARL).

	Reconfigurable computing - Wikipedia, the free encyclopedia
		Reconfigurable computing is computer processing with highly flexible computing fabrics.
		The concept of reconfigurable computing has been around since the 1960s, when Gerald Estrin's landmark paper proposed the concept of a computer consisting of a standard processor and an array of “reconfigurable” hardware.
		Some types of reconfigurable computers are microcoded processors where the microcode is stored in RAM or EEPROM, and changeable on reboot or on the fly.

	Reconfigurable Computing
		The reconfigurable hardware would then be tailored to perform a specific task, such as image processing or pattern matching, as quickly as a dedicated piece of hardware.
		As their functional blocks are optimized for large computations they will perform these operations more quickly and power efficiently than a smaller set of functional units connected together with some interconnect, this is due to the connecting wires are shorter, meaning less wire capacitance and hence faster and lower power designs.
		The consequence of having larger computational blocks is that when the size of operands may not match the algorithm, thereby causing an inefficient utilisation of resources.

	Research in Reconfigurable Computing
		Reconfigurable Computing is a new style of computer architecture enabled by the availability of high density programmable logic chips, or FPGAs (Field Programmable Gate Arrays).
		Reconfigurable computing is a new research area which has developed worldwide over the last decade.
		The significance of reconfigurable computing lies in its ability to deliver computing structures with the speed of dedicated hardware circuits, but with the programmability of software.

	Reconfigurable Computing Primer - FPGAs, dynamic reconfiguration, configurable computing
		Reconfigurable computing allows system designers to execute more hardware than they have gates to fit, which works especially well when there are parts of the hardware that are occasionally idle.
		This is reconfigurable computing at its best, and using this approach it is possible to design systems that do more, cost less, and have shorter design and implementation cycles.
		The principal benefits of reconfigurable computing are the ability to execute larger hardware designs with fewer gates and to realize the flexibility of a software-based solution while retaining the execution speed of a more traditional, hardware-based approach.

	Military & Aerospace Electronics - The new frontier: reconfigurable computing
		Reconfigurable computers — chips or systems that alter their personality to adapt to changing applications through the use of field programmable gate arrays (FPGAs) —; are receiving growing attention.
		Reconfigurable computing systems, which can reconfigure their circuits during operation to adapt to new tasks or failed components, promise to be 100 to 1,000 times faster than microprocessor-based systems that are prevalent today.
		Reconfigurable computers can morph their personalities based on the tasks at hand, whether it is performing Fast Fourier Transforms (FFTs), handling interrupts, or even reconfiguring radar or sonar sensors based on changing mission parameters.

	New NSF Center Targets Reconfigurable Computing
		George: High-performance reconfigurable computing, the focus of CHREC, holds tremendous promise in addressing the needs of a broad range of applications, in areas such as signal and image processing, cryptology, communications processing, data and text mining, optimization, bioinformatics, and complex system simulations.
		Advantages from a reconfigurable approach can be realized in terms of performance, power, size, cooling, cost, versatility, scalability, and dependability to name a few important facets where conventional computing infrastructure alone is proving unable to meet the needs of an increasing number of critical applications.
		Alan D. George is Professor of Electrical and Computer Engineering at the University of Florida, the flagship university in the fourth largest state in the US, where he serves as Director of the HCS Research Laboratory, Chair of the University Committee on High-Performance Computing, and Director of the new NSF Center for High-Performance Reconfigurable Computing.

	Architectures and Compilers to Support Reconfigurable Computing
		The coupling of dedicated hardware to a host computer (as shown in Figure 1) in order to accelerate some computationally intensive tasks, is not a new concept.
		For parallel computations, acceleration is achieved through the exploitation of the parallelism in a program and its mapping onto an architecture of various processors, but for RC it is achieved through the migration of the most computationally-intensive parts of the program to RPUs.
		A proposed reconfiguration based on layers of reconfiguration selected by a context switch has been addressed in [12].

		Whereas most of the problems we are looking at in Scientific computing have a large data path component, the problem of RCM in wireless mobile computing is one that is more control dominated--requiring many parallel state machines that share data paths and communicate, synchronize and coordinate with one another.
		In general, we are looking to explore different mappings of applications--in terms of their algorithms and data structures--onto various reconfigurable computing platforms in an efficient manner.

	Obvious Obscurity » Reconfigurable Computing
		ESL tools, on the other hand, are supposed to allow you to take something more like a computer program written for “temporal” processing on a microprocessor (one instruction at a time) and turn it into hardware for “spatial” processing (many components operating at the same time) on something like an FPGA.
		Reconfigurable Computing has usually meant using programmable logic devices like FPGAs, but this os not necessarily the case.
		After all of this poking around, I’m thinking that it would be nice to use one of these ESL or reconfigurable computing development environments to get some sense of how well they isolate developers from hardware implementation.
