John : Take a look.  https://wodewangzhishime.blogspot.com/2022/02/httpswodewangzhishime_62.html?m=1 . It's an architecture of which there's no difference between parallel and serial input. 

Me: Indeed,  there's no more parallel Input line and no more serial input line.  There's only a line called input line left. 

John : Look at the above 2 pictures. They are case 1 and 2.

.

1) In case 1, b1 is the bit being input.  If (0.1.0.1) gotta be input,  there's no delayed circuit.  Then, 4 bits enter b1 together.  4 bits right shift together. 

2) In case 2, 0 individually enter b1, 1 individually enter b2, 0 individually enter b3, 1 individually enter b4.

.

Me: Ok. 

.

John: Of Case 1 and case 2, which case can result in faster operation. 

.

Me: Both case results in same speed. 

.

John : As a result,  the tendency is no more parallel and serial input line.  The tendency is that there's only a line called input line.
