  Field-programmable gate array - Wikipedia, the free encyclopedia
FPGAs are generally slower than their application-specific integrated circuit (ASIC) counterparts, and draw more power.
Many modern FPGAs have the ability to be reprogrammed at "run time," and this is leading to the idea of reconfigurable computing or reconfigurable systems CPUs that reconfigure themselves to suit the task at hand.

 FPGAs:
An FPGA is a logic chip comprising cells of logic blocks connected with software-configurable interconnections; it is basically a blank slate in which a programmer can build a chip on the fly to implement a finite state machine.
FPGAs have several disadvantages compared to fixed chips, however; the programmability comes with the overhead of extra hardware to perform the programming, slower speed resulting from the extra resistance caused by the programming hardware, and additional cost and size because of the extra hardware.
FPGAs should soon contain even more processor-like capabilites and dedicated memory, further increasing their value in high-throughput computer systems by freeing the processors from ungainly computing tasks with hardware that can adapt itself to the input data as it processes.

 FPGAs and Multicomputers: A Formidable Blend | RTC Magazine
When FPGAs are added to the mix, the general problem is compounded by the relative difficulty in developing for an FPGA, to say nothing of the integration of the FPGA-based application into the larger system.
Implementing an algorithm on an FPGA is roughly 10 to 30 times more difficult—in terms of hours of effort—than programming on a general-purpose device such as a RISC processor.
And, after the required algorithm is running on an FPGA, there is still the task of creating the interfaces so the FPGA can communicate with the rest of the computing system—I/O, memory, and other processors.

 Digital Signal Processing with FPGAs
FPGAs are an array of programmable logic cells interconnected by a matrix of wires and programmable switches..
An FPGA has a large number (64 to over 20,000) of these cells available to use as building blocks in complex digital circuits.
Success of an FPGA DSP design is heavily dependent on the experience of the designer, not only in implementing designs in FPGAs, but also in tailoring algorithms for hardware efficiency.

 Choosing a Real-Time Platform: FPGAs vs. Real-Time Operating Systems on EDN: Voice of the Electronics Engineer
FPGAs (FIELD-PROGRAMMABLE GATE ARRAYS) are ICs that contain large numbers of unconnected gates whose function you determine by downloading to the FPGA a wiring list that determines how the gates interconnect.
NI's LabVIEW FPGA lets you use LabVIEW's familiar graphical-programming environment to develop code for FPGAs and target that code to an FPGA on NI's reconfigurable PXI-7831R board (Figure 1).
The main difference between traditional FPGAs and LabVIEW FPGA is that the PXI-7831R plug-in module is primarily for prototyping special applications, extending measurement and control systems' timing and synchronization capabilities, and where time-to-market is critical.

 Actel: Products & Services: Antifuse Devices: Axcelerator
Built on Actel's innovative sea-of-modules architecture, Axcelerator FPGAs are designed to deliver 100% pure performance without the penalties of high-power, lack of design security, and susceptibility to firm errors associated with SRAM FPGAs.
Since Axcelerator FPGAs are nonvolatile, they are live at power up so there's no in-rush current spike as with SRAM FPGAs, further simplifying system power supply design.
Moving functions into the FPGA that are normally reserved for CPLDs reduces the overall user I/O requirement of the FPGA and can allow for a smaller, cheaper FPGA to be used.

 FPGA-configuration scheme is flexible - 1/22/2004 - EDN - CA373870   (Site not responding. Last check: 2007-11-05)
FPGAs are popular in circuit design because of their flexibility and efficiency.
When you use many FPGAs in a design, it is inadvisable to put a large amount of external memories near the FPGAs.
However, when you want to change only one FPGA's functions and keep others unchanged, it is unwise to reprogram all FPGAs, because it takes a lot of time and can cause unexpected problems in the related circuits.

 Reconfigurable Computing Primer - FPGAs, dynamic reconfiguration, configurable computing
Because not all of the logic must be present in the FPGA at all times, the cost of supporting additional features is reduced to the cost of the memory required to store the logic design.
This means that the FPGA must be reprogrammed in its entirety and that its previous internal state cannot be captured beforehand.
This allows the internal state of the FPGA to be read and written just like memory and makes it possible to “swap” hardware designs in much the same way that pages of virtual memory are swapped into and out of physical memory.

 FPGAs Pave Road to Reconfigurable Computing | COTS Journal
An OFDM receiver was chosen as a benchmark because it is representative of the signal processing tasks found in many kinds of communications applications including DSL, cable modems and fixed wireless systems.
As with most technology selection choices, the decision of whether to use an FPGA for signal processing tasks in a communications infrastructure application requires a sophisticated, multidimensional evaluation that looks beyond raw performance.
In addition, the time required to develop an optimized implementation of even a relatively modest DSP function for an FPGA can be dramatically longer than that required to write an optimized version for a DSP.

This "value-based" segment represents the fastest growing component of the FPGA market and is estimated to be $500M this year.
Unlike SRAM-based FPGAs, on-board security mechanisms prevent access to all the programming information, and reprogramming can be securely performed in-system, using the industry-standard 128-bit AES algorithm to support future design iterations and field upgrades with peace of mind that valuable IP will not be compromised or copied.

 ASICs Vs FPGAs
The design process is similar, but where it diverge is when, for FPGA, you have fixed FPGA cells for which the synthesizer and the place&route will map logic too, where in ASIC, *you* decide what to put, and where, inside the chip (well, the CAD program decides it).
FPGA are getting a lot faster and a lot more dense by the days.
In an FPGA, if a bug is found, a fix can be implemented and tested in the FPGA the very same day.

Abstract: In this paper we describe Frontier, an FPGA placement system that uses design macro-blocks in conjuction with a series of placement algorithms to achieve highly-routable and high-performance layouts quickly.
In the first stage of design placement, a macro-based floorplanner is used to quickly identify an initial layout based on inter-macro connectivity.
Next, an FPGA routability metric, previously described in [14], is used to evaluate the quality of the initial placement.

In this paper we evaluate FPGA technology for use in frequency-domain sonar beamforming.
First, the CORDIC algorithm maps well onto FPGAs; in our case, this allows complex arithmetic to be done in either rectangular or polar forms and, thus, greatly reduces the hardware requirements for the algorithm.
Second, the ability of FPGAs to support multiple memory ports eliminates memory bottlenecks and allows multiple processing elements to be placed into each FPGA, increasing performance via parallelism.
