The 1-bit computer architecture is a microprocessor architecture that has a datapath width or a highest operand width of 1 bit. These architectures typically have a matching register file with registers width of 1 bit. Very few 1-bit architecture CPUs were commercially marketed.

Applications

Some of the earliest calculators had bit-serial architecture, most quickly switched over to 4-bit and then 16-bit microprocessors. Today all 1-bit microprocessors are largely obsolete, even academia.
