'''Bit manipulation instructions''' are [[instruction set architecture|instructions]] that perform [[bit manipulation]] operations in hardware, rather than requiring several instructions for those operations as illustrated with [[Bit manipulation#Example of bit manipulation|examples in software]].<ref>{{cite web | title=Bit Twiddling Hacks | url=https://graphics.stanford.edu/~seander/bithacks.html}}</ref> Several leading as well as historic architectures have bit manipulation instructions including [[ARM]], [[WDC 65C02]], the [[TX-2]] and the [[Power ISA]].<ref>{{cite web | title=Advanced bit manipulation instructions: Architecture, implementation and applications | website=[[ProQuest]] | url=https://www.proquest.com/openview/0ad3a2474b0691b65b35582fbdb3cf40/1?pq-origsite=gscholar&cbl=18750 }}</ref>
