The universal shift register is able to operate in all these modes because of the four-to-one multiplexers that supply the flipflops. Our 4-bit universal shift register is built with four blocks each constituted of a 4X1 mux and a D-flipflop.

LessonNo. 34
Theneed to storagebinarydatawasdiscussedearlier. In digitalcircuitsmulti-bitdata
has to be storedtemporarilyuntil it is processed. A flip-flop is able to store a singlebinarybit of
information.Multiplebits of dataarestored by usingmultipleflip-flopswhichhavetheirclock
inputsconnectedtogether.Thus, by activatingtheclocksignalmultiple-bits of dataarestored.
Technically, a registerperformstwobasicfunctions. It storesdataand it moves or
shiftsdata.Theshifting of datainvolvesshifting of bitsfromoneflip-flop to theotherwithinthe
register or movingdata in andout of theregister.Theshiftoperation of thebinarydata is
carriedout by applyingclocksignals.Severaldifferentkinds of shiftoperationscan be
identified.Thedifferentshiftoperationsaredescribedusing a 4-bitshiftregister.
Data is shifted in theright-handdirectiononebit at a timewitheachtransition of the
clocksignal.Figure34.1.Thedataenterstheshiftregisterseriallyfromthelefthandsideand

applied.Thusafter 8 clocksignalsthe4-bitdata is completelyshiftedout of theshiftregister.

TheSerialShiftregisterhasbeendiscussedearlier,implementedusingJ-Kflip-flops.
Serialshiftregisterscan be implementedusinganytype of flip-flops. A serialshiftregister
implementedusing D flip-flopswiththeserialdataapplied at the D input of thefirstflip-flopand
serialdataoutobtained at the Q output of thelastflip-flop is shown.Figure34.3. At eachclock
transition1bit of serialdata is shifted in and at thesameinstant1-bit of serialdata is shifted
out.For a 4-bitshiftregister, 8 clocktransitionsarerequired to shift in 4-bitdataand
CS302 - Digital Logic & Design
completelyshiftoutthe4-bitdata. As thedata is shiftedout1-bit at a time, a logic 0 value is
usuallyshifted in to fill up thevacantbits in theshiftregister.
Figure34.3bTimingdiagram of a SerialIn/ShiftRight/SerialOutRegister
Theshiftleftandshiftrightshiftregistersareidentical in theirworking.Theyare
connecteddifferentlyforshiftleftandshiftrightoperations.BidirectionalShiftRegistersare
availablewhichallowdata to be shiftedleft or right.Figure34.4.The4-bitregister is
configured to shiftleft or right by settingtheRIGHT / LEFTsignal to logichigh or low
respectively.Whentheregister is configured to shiftright,the AND gatesmarked 1 are
enabled.Theinput of thefirstflip-flop is connected to theserialInput,theinputs of thenext
threeflip-flopsareconnected to the Q outputs of thepreviousflip-flops.Thus on a clock
transitiondata is shifted1-bittowardstheright.Theserialdata is shiftedout of theregister
throughoutput Q3. Whentheregister is configured to shiftleftthe AND gatesmarked 2 are
enabled,connectingthe Q outputs of theflip-flop on therighthandside to the D input of the
flip-flop on thelefthandside.Thus on eachclocktransitiondata is shifted1-bittowardsleft.
