{{Short description|Computational system in which data are sent one bit at a time down a wire}}

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

In [[digitalcomputer logicarchitecture]] applications, '''bit-serial architectures''' send data one bit at a time, along a single wire, in contrast to [[Parallel transmission|bit-parallel]] [[word (computer architecture)|word]] architectures, in which data values are sent all bits or a word at once along a group of wires.

Bit-serial architectures were developed for [[digital signal processing]] in the 1960s through 1980s, including efficient structures for bit-serial multiplication and accumulation.<ref>

All digital computers built before 1951, and most of the early [[massively parallel (computing)|massive parallel processing]] machines used a bit-serial architecture—they were [[serial computer]]s.
