FPGAs originally began as competitors to [[Complex programmable logic device|CPLDs]] to implement [[glue logic]] for [[printed circuit board]]s. As their size, capabilities, and speed increased, FPGAs took over additional functions to the point where some are now marketed as full [[System on a chip|systems on chips]] (SoCs). Particularly with the introduction of dedicated [[Binary multiplier|multiplier]]s into FPGA architectures in the late 1990s, applications which had traditionally been the sole reserve of [[digital signal processor|digital signal processor hardware]] (DSPs) began to incorporate FPGAs instead.<ref>{{cite web|url=https://www.bdti.com/articles/info_eet0207fpga.htm|title=Publications and Presentations|work=bdti.com|access-date=2018-11-02|archive-url=https://web.archive.org/web/20100821182813/http://www.bdti.com/articles/info_eet0207fpga.htm|archive-date=2010-08-21|url-status=dead}}</ref><ref>{{cite web|url=https://www.eetimes.com/xilinx-aims-65-nm-fpgas-at-dsp-applications/#|title=Xilinx aims 65-nm FPGAs at DSP applications|work=EETimes|first=Mark|last=LaPedus|date=5 February 2007 }}</ref>

The evolution of FPGAs has motivated an increase in the use of these devices, whose architecture allows the development of hardware solutions optimized for complex tasks, such as 3D MRI image segmentation, 3D discrete wavelet transform, tomographic image reconstruction, or PET/MRI systems.<ref>{{Cite journal |last1=Alcaín |first1=Eduardo |last2=Fernández |first2=Pedro R. |last3=Nieto |first3=Rubén |last4=Montemayor |first4=Antonio S. |last5=Vilas |first5=Jaime |last6=Galiana-Bordera |first6=Adrian |last7=Martinez-Girones |first7=Pedro Miguel |last8=Prieto-de-la-Lastra |first8=Carmen |last9=Rodriguez-Vila |first9=Borja |last10=Bonet |first10=Marina |last11=Rodriguez-Sanchez |first11=Cristina |date=2021-12-15 |title=Hardware Architectures for Real-Time Medical Imaging |journal=Electronics |language=en |volume=10 |issue=24 |pages=3118 |doi=10.3390/electronics10243118 |issn=2079-9292|doi-access=free }}</ref><ref>{{Cite journal |last1=Nagornov |first1=Nikolay N. |last2=Lyakhov |first2=Pavel A. |last3=Valueva |first3=Maria V. |last4=Bergerman |first4=Maxim V. |date=2022 |title=RNS-Based FPGA Accelerators for High-Quality 3D Medical Image Wavelet Processing Using Scaled Filter Coefficients |journal=IEEE Access |volume=10 |pages=19215–19231 |doi=10.1109/ACCESS.2022.3151361 |s2cid=246895876 |issn=2169-3536|doi-access=free |bibcode=2022IEEEA..1019215N }}</ref> The developed solutions can perform intensive computation tasks with parallel processing, are dynamically reprogrammable, and have a low cost, all while meeting the hard real-time requirements associated with medical imaging.

Another trend in the use of FPGAs is [[hardware acceleration]], where one can use the FPGA to accelerate certain parts of an algorithm and share part of the computation between the FPGA and a generic processor. The search engine [[Bing (search engine)|Bing]] is noted for adopting FPGA acceleration for its search algorithm in 2014.<ref name="BingFPGA">{{cite news |last1=Morgan |first1=Timothy Pricket |title=How Microsoft Is Using FPGAs To Speed Up Bing Search |url=https://www.enterprisetech.com/2014/09/03/microsoft-using-fpgas-speed-bing-search/ |access-date=2018-09-18 |publisher=Enterprise Tech |date=2014-09-03}}</ref> {{as of|2018}}, FPGAs are seeing increased use as [[AI accelerator]]s including Microsoft's so-termed "Project Catapult"<ref name="ProjCatapult">{{cite web|url=https://www.microsoft.com/en-us/research/project/project-catapult/|title=Project Catapult|date=July 2018|website=Microsoft Research}}</ref> and for accelerating [[artificial neural network]]s for [[machine learning]] applications.
