mention an extremely common example of 1-bit architecture |
Guy Harris (talk | contribs) Which calculators? The Intel 4004 and the HP Saturn processors, used in calculators, weren't bit-serial, for example. (Note also that there's "architecturally N-bit" and "N-bit microarchitecture", e.g. the 32-bit S/360-30 with an 8-bit uarch.) |

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.
Most [[calculator]]s use a [[bit serial]] design.{{cn}}
Other examples of 1-bit architectures are [[programmable logic controllers]].
