John : This article is about System bus. https://wodewangzhishime.blogspot.com/2023/12/sequential-90-enabling-line.html?m=1 . You may have a look at it first. Me: Ok. . See the picture above. 1) It is a register of serial input. 2) The field of value of it has 4 bits. 3) The bit of the left-most is the bit of being input. 4) And, ((S.I. Line)) stand for serial input line. 5) This register right shift. . Me: Ok. . John: There're 3 type of data bus of a serial input in term of their width. . 1) Bus width 4 bits. 2) Bus width 8 bits. 3) Bus width 32 bits. . John : In the picture, its Bus width us 4 bits. That mean, during 1 up-cycle of the clock line, maximum 4 bits are allowed to be input together in the field of value of a register of serial input. This 4 ...
