An example of a 1-bit architecture actually marketed as a CPU is the [[Motorola MC14500B]] Industrial Control Unit.<ref>{{cite web|publisher=[[Motorola]]|title=MC14500B Industrial Control Unit. Semiconductor Technical Data, Rev. 3|url=http://www.brouhaha.com/~eric/retrocomputing/motorola/mc14500b/mc14500brev3.pdf|year=1995|accessdate=August 1, 2012}}</ref> There are also several design studies for 1-bit architectures in academia, and corresponding 1-bit logic can also be found in programming.
 
Additional ''boolean processors'' are integrated in some [[microprocessor]]s or [[microcontroller]]s, for example the [[8-bit]] [[Intel MCS-51]] to [[8-bit]]/[[16-bit]]/[[32-bit]] [[Intel MCS-251]] families and derivatives, include a boolean processor. Other examples of 1-bit architectures are [[programmable logic controllers]].
 
A typical sequence of instructions from a program for a 1-bit architecture might be:
