Here is a graphical animation that demonstrates how does a shift register work internally.Īs you might have noticed, the data input (0’s and 1’s) is being shifted from the input pin to the output end at bit-0.
Shift registers are basically some D-Flip-Flops serially connected while sharing the same clock line. So, let’s dig deeper into a shift register in order to build up a complete understanding of what is actually happening at the Register(low)-Level. Shift registers are used to shift out the data to be transmitted bit-by-bit each clock cycle. Frankly speaking, serial communication protocols have Shift Registers somehow/somewhere in their hardware implementation as the working-horse (core). However, it turns out to be some similarity that they do share in common. There do exist many serial communication protocols, each of which is working in a different way. However, even if you transfer fewer data per cycle with a serial transmission, you can do it at much higher frequencies which results in higher net transfer rates than of the parallel communication. Conversely, parallel communication is known to be the process of sending several bits, even bytes, as a whole only in a single clock cycle. It takes a complete clock cycle in order to transfer each bit from an end to the other. In Embedded Systems, Telecommunication, and Data Transmission applications, Serial Communication is known to be the process of sending data one bit at a time (bit-by-bit) sequentially, over the serial bus.
