serial in parallel out

views updated

serial in parallel out (SIPO) A term used to describe a class of digital device that can accept serial sequential n-bit data streams and convert them into parallel n-bit data words. These devices often consist of an n-bit shift register that is serial loaded with n bits of data from the input stream under the control of an external clock (see diagram). The n-bit data word can then be read in parallel form from the shift register. Compare parallel in serial out.
