In digital logic applications, bit-serial architectures send data one bit at a time, along a single wire, in contrast to bit-parallel architectures, in which data values are sent all bits at once along a group of wires.

Bit-serial architectures were developed for digital signal processing

Digital signal processing

Digital signal processing is concerned with the representation of discrete time signals by a sequence of numbers or symbols and the processing of these signals. Digital signal processing and analog signal processing are subfields of signal processing...

 in the 1960s through 1980s, including efficient structures for bit-serial multiplication and accumulation.
