Intel CF+ Interface Usebenzisa Altera MAX Series
CF+ Interface Ukusebenzisa iAltera MAX Series
- Ungasebenzisa i-Altera® MAX® II, MAX V, kunye ne-MAX 10 izixhobo zokuphumeza i-CompactFlash + (CF +) interface. Ixabiso labo eliphantsi, amandla aphantsi kunye neempawu zombane ezilula zibenza zibe zezona zixhobo zilungele ukucwangciswayo kwisixhobo sememori esisebenzisanayo.
- Amakhadi eCompactFlash agcina kwaye athuthe iindlela ezininzi zolwazi lwedijithali (idatha, iaudio, imifanekiso) kunye nesoftware phakathi kobubanzi beenkqubo zedijithali. Umbutho weCompactFlash wazise ingqikelelo yeCF+ yokuphucula ukusebenza kwamakhadi eCompactFlash anezixhobo ze-I/O kunye nokugcinwa kwedatha yemagnethi yedisk ngaphandle kwememori edanyazayo. Ikhadi le-CF + likhadi elincinci le-factory form elibandakanya amakhadi okugcina okukhanya, amakhadi edisk magnetic, kunye namakhadi e-I / O ahlukeneyo akhoyo kwiimarike, njengamakhadi e-serial, amakhadi e-ethernet, kunye namakhadi angenazintambo. Ikhadi le-CF + libandakanya umlawuli odibeneyo olawula ukugcinwa kwedatha, ukubuyiswa kunye nokulungiswa kwephutha, ulawulo lwamandla, kunye nokulawula iwashi. Amakhadi e-CF + angasetyenziswa kunye neeadaptha zokwenziwa kwi-PC-Card uhlobo-II okanye uhlobo-III sokethi.
- Kule mihla, iimveliso ezininzi zabathengi ezifana neekhamera, iiPDA, abashicileli, kunye neelaptops zinesokethi esamkela amakhadi ememori eCompactFlash kunye neCF +. Ukongeza kwizixhobo zokugcina, le sokethi ingasetyenziselwa ukujongana nezixhobo ze-I / O ezisebenzisa i-CF + interface.

Ukusebenzisa i-CF+ Interface enezixhobo ze-Altera
- Ujongano lwekhadi le-CF+ lwenziwe ngumamkeli ngokuqinisekisa umqondiso we-H_ENABLE. Xa ikhadi leCompactFlash lifakwe kwisokethi, izikhonkwane ezibini (CD_1 [1:0]) ziyehla, nto leyo ebonisa ujongano ukuba ikhadi lifakwe ngokufanelekileyo. Ukuphendula kwesi senzo, isignali yokuphazamiseka H_INT yenziwe yi-interface, ngokuxhomekeke kwimeko ye-CD_1 izikhonkwane kunye ne-chip yenza isignali (H_ENABLE).
Isiginali ye-H_READY nayo iyabaniswa nanini na xa iimeko ezifunekayo zihlangatyezwa. Lo mqondiso ubonisa kwiprosesa ukuba i-interface ilungele ukwamkela idatha evela kwiprosesa. Ibhasi yedatha ye-16-bit kwikhadi le-CF + iqhagamshelwe ngqo kumamkeli. Xa inginginya ifumana isignali yokuphazamiseka, iphendula kuyo ngokuvelisa uphawu lokuvuma, H_ACK, ukwenzela ujongano ukubonisa ukuba lufumene uphazamiseko. - Intel Corporation. Onke Amalungelo Agciniwe. I-Intel, i-Intel logo, i-Altera, i-Arria, i-Cyclone, i-Enpirion, i-MAX, i-Nios, i-Quartus kunye ne-Stratix amagama kunye neelogo ziimpawu zorhwebo ze-Intel Corporation okanye ii-subsidiaries zayo e-US kunye / okanye kwamanye amazwe. I-Intel iqinisekisa ukusebenza kweFPGA yayo kunye neemveliso zesemiconductor kwiinkcukacha zangoku ngokuhambelana newaranti esemgangathweni ye-Intel, kodwa inelungelo lokwenza utshintsho kuzo naziphi na iimveliso kunye neenkonzo nangaliphi na ixesha ngaphandle kwesaziso. I-Intel ayithathi xanduva okanye ityala elivela kwisicelo okanye ukusetyenziswa kwalo naluphi na ulwazi, imveliso, okanye inkonzo echazwe apha ngaphandle kokuba kuvunyelwene ngokubhaliweyo yi-Intel. Abathengi be-Intel bayacetyiswa ukuba bafumane inguqulelo yamva nje yeenkcazo zesixhobo ngaphambi kokuba baxhomekeke kulo naluphi na ulwazi olupapashiweyo naphambi kokubeka iiodolo zeemveliso okanye iinkonzo.
- Amanye amagama kunye neempawu zingabangwa njengempahla yabanye. kwaye ikulungele ukwenza eminye imisebenzi. Lo mqondiso usebenza njengenkuthazo; yonke imisebenzi yojongano, inginginya, okanye iprosesa kunye nekhadi leCompactFlash zilungelelaniswe kulo mqondiso. Ujongano lukwajonga uphawu lwe-H_RESET; olu phawu lwenziwa ngumamkeli ukubonisa ukuba zonke iimeko zokuqala kufuneka ziphinde zisetwe.
- I-interface ivelisa i-RESET uphawu kwikhadi le-CompactFlash ebonisa ukuba ukusetha kwakhona zonke iimpawu zayo zokulawula kwimeko yazo engagqibekanga.
- Isiginali ye-H_RESET inokuba yihardware okanye isoftware yenziwe. Ukusetwa ngokutsha kwesoftware kuboniswa yi-MSB yeRejista yoKhetho loLungiselelo ngaphakathi kwekhadi leCF+. Umsingathi uvelisa isignali yokulawula i-4-bit
- H_CONTROL ukubonisa umsebenzi ofunekayo wekhadi leCF+ kujongano lweCF+. I-interface ichaza i-H_CONTROL isignali kwaye ikhupha iimpawu ezahlukeneyo zokulawula ukufunda nokubhala idatha, kunye neenkcukacha zoqwalaselo. Yonke imisebenzi yekhadi idityaniswa nomqondiso we-H_ACK. Kumda oncomekayo we-H_ACK, isixhobo se-Altera esixhaswayo sijonga umqondiso wokusetha kwakhona, kwaye ngokuhambelanayo sikhupha i-HOST_ADDRESS, i-chip vumela (CE_1), i-output enable (OE), bhala yenza (WE), REG_1, kunye neempawu ze-RESET. Nganye kwezi zibonakaliso zinexabiso elichazwe kwangaphambili kuyo yonke imisebenzi ekhankanywe ngasentla. Ezi ziprothokholi eziqhelekileyo, njengoko zichazwa ngumbutho weCompactFlash.
- Isignali ye-H_IOM ibanjwe ephantsi kwimodi yememori eqhelekileyo kwaye iphezulu kwimodi ye-I/O. Imowudi yememori eqhelekileyo ivumela ukubhala nokufunda zombini i-8-bit kunye ne-16-bit data.
- Kwakhona, iiRejista zoLungiselelo kwirejista ye-CF+ yolungiselelo lwekhadi, iRejista yeSimo seKhadi, kunye neRejista yokuTshintshwa kwePin ziyafundwa kwaye zibhalwe kuyo. I-4-bit ububanzi H_CONTROL [3:0] isignali ekhutshwe ngumamkeli iyahlula phakathi kwayo yonke le misebenzi. I-interface ye-CF + ichaza i-H_CONTROL kwaye ikhupha iimpawu zolawulo kwikhadi le-CF + ngokweenkcukacha zeCF +. Idatha yenziwe ifumaneke kwibhasi yedatha ye-16-bit emva kokuba iimpawu zolawulo zikhutshwe. Kwimo ye-I / O, ukusetwa kwakhona kwesoftware (eyenziwe ngokwenza i-MSB yeRejista yokuKhetha uLungiselelo kwi-CF + khadi ephezulu) ihlolwe. I-Byte kunye negama lomsebenzi wofikelelo lwenziwa lujongano ngendlela efana naleyo ikwimo yememori echazwe ngasentla.
Umzobo 1: Iimpawu eziDityanisiweyo ezahlukeneyo ze-CF + Interface kunye nesixhobo seCF +
- Lo mzobo ubonisa umzobo webhloko osisiseko wokuphumeza ujongano lweCF+.
