Question 1218 – Nielit STA [02-12-2018]

SIPO is the register is loaded with serial data, one bit at a time, with the stored data being available at the output in parallel form.
SIPO:
A serial-in, parallel-out shift register is similar to the serial-in, serial-out shift register in that it shifts data into internal storage elements and shifts data out at the serial-out, data-out, pin. It is different in that it makes all the internal stages available as outputs. Therefore, a serial-in, parallel-out shift register converts data from serial format to parallel format.
More Information
Serial-in to Serial-out (SISO) – the data is shifted serially “IN” and “OUT” of the register, one bit at a time in either a left or right direction under clock control.
Parallel-in to Serial-out (PISO) – the parallel data is loaded into the register simultaneously and is shifted out of the register serially one bit at a time under clock control.
Parallel-in to Parallel-out (PIPO) – the parallel data is loaded simultaneously into the register, and transferred together to their respective outputs by the same clock pulse.
