Impazamo eqhelekileyo 17: Ezi miqondiso zebhasi zonke zitsalwa ngabaphikisi, ngoko ndiziva ndikhululekile.
Isisombululo esifanelekileyo: Zininzi izizathu zokuba imiqondiso kufuneka ikhutshelwe kwaye ihle, kodwa ayizizo zonke ezo zonke zinokutsalwa. Ukudodobala kunye nokutsala ezantsi kutsala umqondiso wegalelo elilula, kwaye okwangoku ingaphantsi kwamashumi ee-microamperes, kodwa xa isiginali eqhutywa, iya kufikelela kwinqanaba lemiliwa. Inkqubo yangoku ihlala inee-bits zedilesi yedatha, kwaye kunokubakho ukuba i-244/2 i-244/245 ye-244/24 ye-Statting ikhutshelwe apha (musa ukusebenzisa ingcinga ye-84 ye-chilot-iyure yokusetyenziswa kwamandla, isizathu siphantsi.
Impazamo eqhelekileyo 18: Inkqubo yethu ixhotyisiwe yi-220v, ngoko akufuneki sikhathalele ukusetyenziswa kwamandla.
Isisombululo esifanelekileyo: Uyilo lwamandla olusezantsi asikokuthi kuphela ngenxa yokonga amandla, kodwa nokunciphisa iindleko zeemodyuli zamandla kunye neenkqubo zokupholisa, kunye nokunciphisa ukuphazamiseka kwe-elektromagnec kunye nengxolo ye-elermat ngenxa yokuncitshiswa kwangoku. Njengoko iqondo lobushushu lesixhobo liyancipha, ubomi besixhobo buyandiswa ngokudibeneyo (ubushushu bokusebenza kwesixhobo se-semiconductonyuka nge-10 degrees, kwaye ubomi bunqamlezwe sisiqingatha). Ukusetyenziswa kwamandla kufuneka kuqwalaselwe nangaliphi na ixesha.
Impazamo eqhelekileyo 19: Ukusetyenziswa kwamandla kwezi chips ezincinci kuncinci, sukukhathazeka ngayo.
Isisombululo esifanelekileyo: Kunzima ukumisela ukusetyenziswa kwamandla kwi-chip engapheliyo. Kuxhomekeka ikakhulu ngePIN. I-ABT16244 isebenzisa ngaphantsi kwe-1 ma ngaphandle komthwalo, kodwa isalathiso sayo sisiphithiphithi ngasinye. Inokuqhuba umthwalo wama-60 Ewe, kuphela amandla akhoyo ekhoyo, kwaye ubushushu buwela kulo mthwalo.
Impazamo eqhelekileyo 20: Indlela yokujongana nezi zibuko ze-I / O kunye ne-CPU kunye ne-FPGA? Ungayishiya ingenanto kwaye uthethe ngayo kamva.
Isisombululo esifanelekileyo: Ukuba amazibuko angasetyenziswanga i-I / O Ukuba ikhutshiwe, iPIN nganye iya kuba ne-microampere yangoku, ke yeyona ndlela ilungileyo kukuyibeka njengemveliso (kunjalo, akukho miqondiso inokuqhuba ingaxhunyiwe ngaphandle).
Impazamo eqhelekileyo 21: Kukho iminyango eninzi ishiywe kule fpga, ukuze uyisebenzise.
Isisombululo esifanelekileyo: Ukusetyenziswa kwamandla kwi-FGPA kulinganayo kwinani leeflip-flops ezisetyenzisiweyo kunye nenani leeflethi, ke ukuselwa kwaMandla kuhlobo olufanayo lwe-FPGA kwisekethe eyahlukileyo kunye namaxesha ahlukeneyo ahlukile. Ukunciphisa inani le-flip-flops ye-pipping ephezulu yesantya yindlela esisiseko yokunciphisa ukusetyenziswa kwamandla e-FPGA.
Impazamo eqhelekileyo 22: Inkumbulo ineempawu ezininzi zolawulo. Ibhodi yam kufuneka isebenzise i-OE kwaye sibonisa. I-chip ikhethe kufuneka ibekwe, ukuze idatha iphume ngokukhawuleza ngokukhawuleza ngexesha lokufunda.
Isisombululo esifanelekileyo: Ukusetyenziswa kwamandla kwiinkumbulo ezininzi xa ukhetho lwe-chip lusebenza (nokuba ziyi-OE kwaye thina) siya kuba ngaphezulu kwe-100 ka-Thip elingasebenziyo. Ke ngoko, ii-CS kufuneka zisetyenziselwe ukulawula i-chip kangangoko kunokwenzeka, kwaye ezinye iimfuno kufuneka zifezekiswe. Kuyenzeka ukuba ububanzi be-chip khetha i-pullar.
Impazamo eqhelekileyo 23: Ukunciphisa ukusetyenziswa kwamandla ngumsebenzi wabasebenzi be-hadware, kwaye awunanto yakwenza nesoftware.
Isisombululo esifanelekileyo: I-Hardware lixesha nje, kodwa isoftware ngumdlali. Ukufikelela phantse i-chip nganye ebhasini kunye neflip yayo yonke imiqondiso iphantse ilawulwa yisoftware. Ukuba isoftware inokunciphisa inani lokufikelela kwimemori yangaphandle (kusetyenziswa irejista engaphezulu, ukusetyenziswa ngakumbi kwe-cache yangaphakathi, njl njl. Ukuze iBhodi iguquke kakuhle, i-Hardware kunye nesoftware kufuneka ithathelwe yizandla zozibini!
Impazamo eqhelekileyo 24: Kutheni le miqondiso ijonge ngaphezulu? Logama nje umdlalo ulungile, unokupheliswa.
Isisombululo esifanelekileyo: Ngaphandle kweempawu ezimbalwa (ezinje nge-100BAse-T, i-CML), kukho i-Overshoot. Logama nje inkulu kakhulu, akufunekanga ukuba ihambelane. Nokuba ihambelana, ayidibani neyona ilungileyo. Umzekelo, imvume yokukhupha i-TTL ingaphantsi kwama-50 ee-ohms, kunye nama-20 ohms. Ukuba ukuchasana okukhulu okusebenzayo kusetyenziswa, okwangoku kuya kuba mkhulu kakhulu, ukusetyenziswa kwamandla kuya kuba mkelekile, kwaye i-amllingm incinci kakhulu iya kuba incinci kakhulu ukuba ingasetyenziswa. Ngaphandle koko, ukujongwa kwemveliso yophawu ngokubanzi xa kukhutshelwa kwinqanaba eliphezulu kunye nokukhuphela inqanaba eliphantsi alifani, kwaye kunokwenzeka ukufezekisa ngokuhambelana ngokupheleleyo. Ke ngoko, ukutshata kwe-TTL, i-LVD, i-422 kunye neminye imiqondiso inokwamkelwa ixesha elide.
