Control bus - nqa cov cim tswj ntawm lub processor mus rau lwm yam khoom. Lub npav tswj hwm kuj nqa lub moos pulses. Lub tsheb npav tswj yog unidirectional.
Lub npav tswj hwm yog dab tsi?
Hauv computer architecture, lub tsheb npav tswj yog ib feem ntawm lub tsheb npav thiab siv los ntawm CPUs rau kev sib txuas lus nrog lwm yam khoom sivhauv computer.
Lub npav kev sib txuas lus twg yog unidirectional?
Lub npav tswj hwm yog unidirectional vim nws tswj kev ua haujlwm ntawm chaw nyob thiab cov ntaub ntawv tsheb npav. Lub tsheb npav tswj yog lub tsheb npav hauv computer uas siv los ntawm CPU los sib txuas lus nrog cov khoom siv uas muaj nyob hauv lub computer. Nquag Tswj tsheb npav yog unidirectional.
Puas yog bidirectional ib lub tsheb npav?
Chaw nyob tsheb npav yog Unidirectional vim tias microprocessor tab tom hais txog qhov chaw nco tshwj xeeb. Tsis muaj cov khoom siv sab nraud tsis tuaj yeem sau rau hauv Microprocessor. Data bus yog Bidirectional vim tias Microprocessor tuaj yeem nyeem cov ntaub ntawv los ntawm lub cim xeeb lossis sau cov ntaub ntawv rau lub cim xeeb. Nquag Tswj tsheb npav yog unidirectional.
Dab tsi yog lub tsheb npav bidirectional data?
Cov ntaub ntawv tsheb npav yog bidirectional vim cov ntaub ntawv ntws hauv ob qho kev qhia, los ntawm microprocessor mus rau lub cim xeeb lossis cov khoom siv nkag / tso tawm thiab los ntawm lub cim xeeb lossis cov khoom siv nkag / tawm mus rau microprocessor. … Ib lub npav 16 me ntsis tuaj yeem nqa 0 txog 65535.
