=====Reconfigurable computing with field-programmable gate arrays=====
[[Reconfigurable computing]] is the use of a [[field-programmable gate array]] (FPGA) as a co-processor to a general-purpose computer. An FPGA is, in essence, a computer chip that can rewire itself for a given task.

FPGAs can be programmed with [[hardware description language]]s such as [[VHDL]]<ref>{{Cite journal|last1=Valueva|first1=Maria|last2=Valuev|first2=Georgii|last3=Semyonova|first3=Nataliya|last4=Lyakhov|first4=Pavel|last5=Chervyakov|first5=Nikolay|last6=Kaplun|first6=Dmitry|last7=Bogaevskiy|first7=Danil|date=2019-06-20|title=Construction of Residue Number System Using Hardware Efficient Diagonal Function|journal=Electronics|language=en|volume=8|issue=6|pages=694|doi=10.3390/electronics8060694|issn=2079-9292|quote=All simulated circuits were described in very high speed integrated circuit (VHSIC) hardware description language (VHDL).

The best known C to HDL languages are [[Mitrionics|Mitrion-C]], [[Impulse C]], and [[Handel-C]]. Specific subsets of [[SystemC]] based on C++ can also be used for this purpose.

AMD's decision to open its [[HyperTransport]] technology to third-party vendors has become the enabling technology for high-performance reconfigurable computing.<ref name="DAmour">D'Amour, Michael R., Chief Operating Officer, DRC Computer Corporation.
