Line 9:

A '''1-bit''' [[computer architecture]] is an [[instruction set architecture]] for a processor that has [[datapath]] widths and [[processor register|data register]] widths of 1 bit (1/8 [[Octet (computing)|octet]]) wide.

An example of a 1-bit architecture actually marketed as a CPU is the [[Motorola]]'s [[Motorola_MC14500B|MC14500MC14500B]] 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.

Other examples of 1-bit architectures are [[programmable logic controllers]].
