Intel CF + Interface Siv Altera MAX Series
CF + Interface siv Altera MAX Series
- Koj tuaj yeem siv Altera® MAX® II, MAX V, thiab MAX 10 li los siv CompactFlash + (CF+) interface. Lawv cov nqi qis, qis zog thiab yooj yim lub zog-on nta ua rau lawv qhov zoo tshaj plaws programmable logic li rau nco ntaus ntawv-interfacing daim ntaub ntawv.
- CompactFlash phaib khaws thiab thauj ntau hom ntaub ntawv digital (cov ntaub ntawv, suab, duab) thiab software nruab nrab ntawm qhov dav dav ntawm cov tshuab digital. Lub koom haum CompactFlash tau qhia txog CF + lub tswv yim los txhim kho kev ua haujlwm ntawm CompactFlash phaib nrog I / O pab kiag li lawm thiab sib nqus disk cov ntaub ntawv khaws cia sib nrug ntawm flash nco. CF + daim npav yog daim npav me me uas suav nrog cov ntawv ntim ntim ntim ntim, daim npav sib nqus disk, thiab ntau yam I / O phaib uas muaj nyob rau hauv khw, xws li serial cards, ethernet cards, thiab wireless phaib. CF + daim npav muaj xws li ib qho kev tswj xyuas uas tswj cov ntaub ntawv khaws cia, rov qab thiab kho qhov yuam kev, tswj fais fab, thiab tswj lub moos. CF + phaib tuaj yeem siv nrog cov khoom siv tsis zoo hauv PC-Card hom-II lossis hom-III sockets.
- Niaj hnub no, ntau yam khoom siv xws li koob yees duab, PDAs, tshuab luam ntawv, thiab lub laptops muaj lub qhov (socket) uas lees txais CompactFlash thiab CF + nco phaib. Ntxiv nrog rau cov khoom siv cia, lub qhov (socket) no tuaj yeem siv los cuam tshuam I / O cov khoom siv uas siv CF + interface.

Siv CF + Interface nrog Altera Devices
- CF + daim npav interface tau qhib los ntawm tus tswv tsev los ntawm kev lees paub H_ENABLE teeb liab. Thaum daim npav CompactFlash muab tso rau hauv lub qhov (socket), ob tus pins (CD_1 [1: 0]) mus qis, qhia rau lub interface tias daim npav tau muab tso rau hauv zoo. Hauv kev teb rau qhov kev txiav txim no, lub teeb liab cuam tshuam H_INT yog tsim los ntawm lub interface, nyob ntawm seb cov xwm txheej ntawm CD_1 tus pins thiab nti ua kom teeb liab (H_ENABLE).
Lub H_READY teeb liab kuj tau lees paub thaum twg raws li qhov yuav tsum tau ua. Cov teeb liab no qhia rau tus processor tias lub interface yog npaj los txais cov ntaub ntawv los ntawm processor. Lub npav 16-ntsis cov ntaub ntawv mus rau CF + daim npav txuas ncaj qha rau tus tswv tsev. Thaum tus tswv tsev tau txais cov teeb liab cuam tshuam, nws teb rau nws los ntawm kev tsim cov teeb liab lees paub, H_ACK, rau lub interface qhia tias nws tau txais kev cuam tshuam. - Intel Corporation. Txhua txoj cai. Intel, Intel lub logo, Altera, Arria, Cyclone, Enpirion, MAX, Nios, Quartus thiab Stratix cov lus thiab lub logo yog cov cim lag luam ntawm Intel Corporation lossis nws cov koom tes hauv Asmeskas thiab / lossis lwm lub tebchaws. Intel lav kev ua tau zoo ntawm nws cov FPGA thiab cov khoom lag luam semiconductor rau cov kev qhia tshwj xeeb tam sim no raws li Intel tus qauv kev lees paub, tab sis muaj txoj cai los hloov cov khoom thiab cov kev pabcuam txhua lub sijhawm yam tsis muaj ntawv ceeb toom. Intel xav tias tsis muaj lub luag haujlwm lossis kev lav phib xaub uas tshwm sim los ntawm daim ntawv thov lossis siv cov ntaub ntawv, cov khoom lag luam, lossis cov kev pabcuam uas tau piav qhia hauv no tshwj tsis yog raws li tau pom zoo hauv kev sau ntawv los ntawm Intel. Intel cov neeg siv khoom tau qhia kom tau txais qhov tseeb version ntawm cov cuab yeej tshwj xeeb ua ntej tso siab rau cov ntaub ntawv tshaj tawm thiab ua ntej muab xaj rau cov khoom lossis cov kev pabcuam.
- Lwm lub npe thiab cov npe yuav raug lees paub tias yog cov cuab yeej ntawm lwm tus. thiab npaj ua haujlwm ntxiv. Cov teeb liab no ua raws li kev txhawb nqa; tag nrho cov haujlwm ntawm lub interface, tus tswv tsev, lossis tus processor thiab CompactFlash card yog synchronized rau lub teeb liab no. Lub interface kuj kuaj xyuas H_RESET teeb liab; cov teeb liab no yog tsim los ntawm tus tswv tsev los qhia tias txhua yam kev mob pib yuav tsum tau rov pib dua.
- Lub interface nyob rau hauv lem generates RESET teeb liab mus rau lub CompactFlash daim ntawv qhia rau nws kom rov pib dua tag nrho nws cov kev tswj cov cim rau lawv lub neej ntawd mob.
- H_RESET teeb liab tuaj yeem yog kho vajtse lossis software tsim. Lub software rov pib dua yog qhia los ntawm MSB ntawm Configuration Option Register nyob rau hauv daim npav CF +. Tus tswv tsev tsim lub teeb liab 4-ntsis tswj
- H_CONTROL los qhia qhov xav tau ua haujlwm ntawm CF + daim npav rau CF + interface. Lub interface txiav txim siab H_CONTROL teeb liab thiab teeb meem ntau yam kev tswj cov cim los nyeem thiab sau cov ntaub ntawv, thiab cov ntaub ntawv teeb tsa. Txhua daim npav ua haujlwm yog synchronized rau H_ACK teeb liab. Ntawm qhov zoo ntawm H_ACK, qhov kev txhawb nqa Altera ntaus ntawv kuaj xyuas lub teeb liab pib dua, thiab cuam tshuam cov teeb meem HOST_ADDRESS, nti pab (CE_1), tso zis tso zis (OE), sau ua haujlwm (WE), REG_1, thiab RESET teeb liab. Txhua yam ntawm cov teeb liab no muaj tus nqi ua ntej rau tag nrho cov haujlwm tau hais los saum no. Cov no yog cov qauv kev cai, raws li tau hais los ntawm CompactFlash koom haum.
- H_IOM teeb liab tau tuav qis hauv hom kev nco thiab siab hauv I / O hom. Hom kev nco zoo tso cai rau kev sau ntawv thiab nyeem ntawm 8-ntsis thiab 16-ntsis cov ntaub ntawv.
- Tsis tas li ntawd, Configuration Registers nyob rau hauv CF + daim npav xaiv qhov kev xaiv sau npe, Daim Ntawv Teev Npe Sau Npe, thiab Pin Replacement Register raug nyeem los ntawm thiab sau rau hauv. 4-ntsis dav H_CONTROL [3:0] teeb liab tawm los ntawm tus tswv tsev sib txawv ntawm txhua qhov haujlwm no. CF + interface txiav txim siab H_CONTROL thiab teeb tsa kev tswj cov cim rau CF + daim npav raws li CF + cov lus qhia. Cov ntaub ntawv yog tsim muaj nyob rau ntawm 16-ntsis cov ntaub ntawv tsheb npav tom qab cov teeb liab tswj tau raug tso tawm. Nyob rau hauv hom I / O, lub software rov pib dua (tsim los ntawm kev ua MSB ntawm Configuration Option Register hauv CF + card siab) raug kuaj xyuas. Byte thiab lo lus nkag mus ua haujlwm raug tua los ntawm kev sib tham hauv ib yam zoo ib yam li cov hauv hom kev nco tau piav qhia saum toj no.

Kev nqis tes ua
- Cov qauv no tuaj yeem siv tau siv MAX II, MAX V, thiab MAX 10 li. Cov qauv tsim cov cai tswj hwm MAX II (EPM240) thiab MAX 10 (10M08) raws li. Cov qauv tsim cov lej no tau muab tso ua ke thiab tuaj yeem ua haujlwm ncaj qha rau MAX li.
- Rau MAX II tsim example, daim ntawv qhia tus tswv tsev thiab CF + interfacing ports kom haum GPIOs. Qhov kev tsim no siv li ntawm 54% ntawm tag nrho cov LEs hauv EPM240 ntaus ntawv thiab siv 45 I / O tus pins.
- MAX II design example siv CF + ntaus ntawv, uas ua haujlwm nyob rau hauv ob hom: PC Card ATA siv I / O hom thiab PC Card ATA siv hom nco. Qhov thib peb xaiv hom, True IDE hom, tsis suav nrog. MAX II ntaus ntawv ua haujlwm ua tus tswj hwm tus tswv thiab ua tus choj ntawm tus tswv tsev thiab CF + daim npav.
