== History ==

The FPGA industry sprouted from [[programmable read-only memory]] (PROM) and [[programmable logic devices]] (PLDs). PROMs and PLDs both had the option of being programmed in batches in a factory or in the field (field-programmable). However, programmable logic was hard-wired between logic gates.<ref name="history">{{Wayback |date=20070412183416webarchive |url=https://web.archive.org/web/20070412183416/http://filebox.vt.edu/users/tmagin/history.htm |date=April 12, 2007 |title=History of FPGAs }}</ref>

In the late 1980s, the [[Naval Surface Warfare Center]] funded an experiment proposed by Steve Casselman to develop a computer that would implement 600,000 reprogrammable gates. Casselman was successful and a patent related to the system was issued in 1992.<ref name="history" />
