Question

4. The block diagram of a bidirectional shift register is 2-bit code (SL, SR) with the operations performed listed in nal shift register is given below. This register is controlled by a ons performed listed in the table below. SR In SL SR SL SL In 0 Bidirectional Shift Register SHR SR- 0 Operation Hold Shift Right Shift Left Not allowed (Don't Care) 0 Clock 11 Manually simulate the register for 8 clock cycles with the initial contents and inputs as given in the simulation table below. The results due to any given line of the table are to appear on the following line due to the positive clock edge triggering of the register. Clock Cycle SL SR SL_In SR_In 7 1 0 Shift Register Contents 5 4 3 2 1 0 1 0 1 6 0 0 0 1 0 1 0 | 0 1 1 0 1 0 1 1 0 0 1 10 10 01 0

please explain in words how

Answer 1

Bidirectional Shift register :- are the Storage devices which cie capable of Shifting the data either right or legt depending on the mode Selected. Figure a shows an o-bit bichrectional shift register with serial data cocoding and retrieual capacity, initially all the Alp flops in the register are: Meset by driving their clear pins high - Alert Rhut.... control line i made either low or high in order to opt for either left-shift or right-shift of the data bits, respectively. clock shift Registey Contents SL SR | SL-in SR-In cycle - - e + 0 o
