In computer architecture, 1-bit integers, memory addresses, or other data units are those that are 1 bits (1/8 octets) wide. Also, 1-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size.
An example of a 1-bit architecture actually marketed as a CPU is Motorola's MC14500 Industrial Control Unit.[1] There are also several design studies for 1-bit architectures in academia, and corresponding 1-bit logic can also be found in programming.
Another example of 1-bit architectures are programmable logic controllers.
