What is Field Programmable Gate Array (FPGA)

Chapter 3
Handbook of Research on Computational Science and Engineering: Theory and Practice
is a reconfigurable electronic device with fine-grain architecture that implements customized computational logic specific to the application being executed, and can be reconfigured for a wide range of tasks (Maxfield, 2004). Its reconfigurable architecture is composed of: processing elements called Look-Up-Tables (LUTs) that can implement any logic function with few inputs, an interconnection network that can connect any logic cell with the rest of the circuit, memory blocks that store data to be loaded by any other element of the architecture, and special modules that are integrated on chip to efficiently do a frequently used task such as multiplications, digital signal processing, and external input-output interfacing.

Abstract
Many accelerator-based computers have demonstrated that they can be faster and more energy-efficient than traditional high-performance multi-core computers. Two types of programmable accelerators are available in high-performance computing: general-purpose accelerators such as GPUs, and customizable accelerators such as FPGAs, although general-purpose accelerators have received more attention. This chapter reviews the state-of-the-art and current trends of high-performance customizable computers (HPCC) and their use in Computational Science and Engineering (CSE). A top-down approach is used to be more accessible to the non-specialists. The “top view” is provided by a taxonomy of customizable computers. This abstract view is accompanied with a performance comparison of common CSE applications on HPCC systems and high-performance microprocessor-based computers. The “down view” examines software development, describing how CSE applications are programmed on HPCC computers. Additionally, a cost analysis and an example illustrate the origin of the benefits. Finally, the future of the high-performance customizable computing is analyzed.

Evolvable Hardware
A programmable chip that contains logic gates as well as that can be arranged in different ways. To receive different configurations, the FPGA is connected through an interface to a computer which contains vendor specific software that offers to the developer two kinds of specification languages: one graphical and the other textual. VHDL (IEEE Standardized), Verilog, and AHDL are examples of the textual description languages.
