Intel CF+ Interface Pogwiritsa Ntchito Altera MAX Series

CF+ Interface Pogwiritsa Ntchito Altera MAX Series

• Mutha kugwiritsa ntchito zida za Altera® MAX® II, MAX V, ndi MAX 10 kuti mugwiritse ntchito mawonekedwe a CompactFlash+ (CF+). Mawonekedwe awo otsika mtengo, otsika komanso osavuta kugwiritsa ntchito mphamvu amawapanga kukhala zida zolongosoka zomangika pamakina ogwiritsira ntchito kukumbukira.
• Makhadi a CompactFlash amasunga ndi kutumiza mitundu ingapo ya zidziwitso za digito (data, zomvera, zithunzi) ndi mapulogalamu pakati pa nthawi yayitali yamakina a digito. Bungwe la CompactFlash lidayambitsa lingaliro la CF + kuti lipititse patsogolo magwiridwe antchito a makhadi a CompactFlash okhala ndi zida za I/O komanso kusungirako deta ya maginito popanda kukumbukira flash. Khadi la CF+ ndi kakhadi kakang'ono kamene kamakhala ndi makadi osungira ophatikizika, makadi a maginito disk, ndi makadi osiyanasiyana a I/O omwe amapezeka pamsika, monga serial cards, ethernet cards, and wireless cards. Khadi la CF + limaphatikizapo chowongolera chophatikizidwa chomwe chimayendetsa kusungirako deta, kubweza ndi kukonza zolakwika, kasamalidwe ka mphamvu, ndi kuwongolera koloko. CF + makadi angagwiritsidwe ntchito ndi adaputala kungokhala mu PC-Card mtundu-II kapena mtundu-III sockets.
• Masiku ano, zinthu zambiri zogula monga makamera, PDAs, osindikiza, ndi ma laputopu ali ndi socket yomwe imavomereza makadi okumbukira a CompactFlash ndi CF +. Kuphatikiza pazida zosungirako, socket iyi ingagwiritsidwenso ntchito polumikizira zida za I / O zomwe zimagwiritsa ntchito mawonekedwe a CF +.

Zambiri Zogwirizana

Design Example kwa MAX 10

• Amapereka mapangidwe a MAX 10 files pa cholemba ichi (AN 492)

Kuwongolera Mphamvu mu Ma Portable Systems Pogwiritsa Ntchito Altera Devices

• Amapereka zambiri zokhudzana ndi kasamalidwe ka mphamvu mumakina osunthika pogwiritsa ntchito zida za Altera

MAX II Maupangiri Opangira Zida

• Imakupatsirani zambiri za malangizo opangira zida za MAX II

Kugwiritsa ntchito CF + Interface yokhala ndi Altera Devices

• Mawonekedwe a CF+ khadi amayatsidwa ndi wolandirayo potsimikizira chizindikiro cha H_ENABLE. Khadi la CompactFlash likalowetsedwa mu socket, mapini awiri (CD_1 [1:0]) amatsika, kusonyeza mawonekedwe kuti khadiyo adayikidwa bwino. Poyankha izi, chizindikiro chosokoneza H_INT chimapangidwa ndi mawonekedwe, kutengera momwe CD_1 mapini alili komanso siginecha yolumikizira chip (H_ENABLE).
  Chizindikiro cha H_READY chimatsimikiziridwanso nthawi iliyonse yomwe zofunikira zikwaniritsidwa. Chizindikiro ichi chimasonyeza kwa purosesa kuti mawonekedwewo ali okonzeka kuvomereza deta kuchokera kwa purosesa. Basi ya data ya 16-bit yopita ku CF + khadi imalumikizidwa mwachindunji kwa wolandirayo. Wolandirayo akalandira chizindikiro chosokoneza, amayankha popanga chizindikiro chovomerezeka, H_ACK, kuti mawonekedwe asonyeze kuti walandira kusokoneza.
• Malingaliro a kampani Intel Corporation Maumwini onse ndi otetezedwa. Intel, logo ya Intel, Altera, Arria, Cyclone, Enpirion, MAX, Nios, Quartus ndi Stratix mawu ndi logo ndi zizindikiro za Intel Corporation kapena mabungwe ake ku US ndi/kapena mayiko ena. Intel imatsimikizira kugwira ntchito kwa FPGA yake ndi zida za semiconductor malinga ndi zomwe zili pano malinga ndi chitsimikizo cha Intel, koma ili ndi ufulu wosintha zinthu ndi ntchito zilizonse nthawi iliyonse popanda kuzindikira. Intel sakhala ndi udindo kapena udindo chifukwa cha kugwiritsa ntchito kapena kugwiritsa ntchito zidziwitso zilizonse, malonda, kapena ntchito zomwe zafotokozedwa pano kupatula monga momwe Intel adavomerezera momveka bwino. Makasitomala a Intel amalangizidwa kuti apeze mtundu waposachedwa kwambiri wamakina a chipangizocho asanadalire zidziwitso zilizonse zosindikizidwa komanso asanayike maoda azinthu kapena ntchito.
• Mayina ena ndi mtundu zitha kunenedwa kuti ndi za ena. ndipo ali wokonzeka kugwira ntchito zina. Chizindikiro ichi chimagwira ntchito ngati chilimbikitso; ntchito zonse za mawonekedwe, wolandila, kapena purosesa ndi CompactFlash khadi zimalumikizidwa ndi chizindikirochi. Mawonekedwewa amayang'ananso chizindikiro cha H_RESET; chizindikiro ichi chimapangidwa ndi wolandirayo kuti asonyeze kuti zonse zoyamba ziyenera kukhazikitsidwa.
• Mawonekedwewo amapanga chizindikiro cha RESET ku khadi la CompactFlash kusonyeza kuti akhazikitsenso zizindikiro zake zonse kuti zikhale zokhazikika.
• Chizindikiro cha H_RESET chikhoza kukhala hardware kapena mapulogalamu opangidwa. Kukhazikitsanso mapulogalamu kumasonyezedwa ndi MSB ya Configuration Option Register mkati mwa CF+ khadi. Wolandirayo amapanga chizindikiro chowongolera cha 4-bit
• H_CONTROL kusonyeza ntchito yomwe mukufuna CF+ khadi ku mawonekedwe a CF+. Mawonekedwewa amazindikira siginecha ya H_CONTROL ndikupereka masigino osiyanasiyana oti muwerenge ndi kulemba deta, komanso zambiri zamasinthidwe. Ntchito iliyonse yamakhadi imalumikizidwa ndi siginecha ya H_ACK. Pamphepete mwa H_ACK, chipangizo chothandizira cha Altera chimayang'ana chizindikiro chokhazikitsanso, ndipo mofananamo chimatulutsa HOST_ADDRESS, chip enable (CE_1), kutuluka yambitsani (OE), kulemba yambitsani (WE), REG_1, ndi zizindikiro za RESET. Chilichonse mwazizindikirozi chimakhala ndi mtengo wodziwikiratu pazochita zonse zomwe tazitchula pamwambapa. Awa ndi ma protocol okhazikika, monga akufotokozera mgwirizano wa CompactFlash.
• Chizindikiro cha H_IOM chimakhala chotsika pamakumbukiro wamba komanso apamwamba mumayendedwe a I/O. Memory wamba amalola kulemba ndi kuwerenga zonse za 8-bit ndi 16-bit data.
• Komanso, Zolembetsa Zosintha mu kaundula wa kasinthidwe ka CF + makadi, Kaundula wa Makhadi, ndi Kaundula wa Pin Replacement amawerengedwa ndikulembedwa. Chizindikiro cha 4-bit wide H_CONTROL [3:0] choperekedwa ndi wolandirayo chimasiyanitsa ntchito zonsezi. Mawonekedwe a CF+ amasankha H_CONTROL ndikupereka ma siginecha owongolera ku CF+ khadi molingana ndi CF+. Deta imapangidwa kuti ipezeke pa basi ya data ya 16-bit pambuyo potulutsa zowongolera. Mu mawonekedwe a I / O, kukonzanso mapulogalamu (opangidwa popanga MSB ya Configuration Option Register mu CF + khadi yapamwamba) imafufuzidwa. Ma Byte ndi mawu ofikira amachitidwa ndi mawonekedwe m'njira yofanana ndi yomwe ili mumkhalidwe wa kukumbukira womwe wafotokozedwa pamwambapa.

Kukhazikitsa

• Mapangidwe awa atha kukhazikitsidwa pogwiritsa ntchito zida za MAX II, MAX V, ndi MAX 10. Mapangidwe omwe aperekedwa amalunjika ku MAX II (EPM240) ndi MAX 10 (10M08) motsatana. Ma code source sources awa amapangidwa ndipo amatha kusinthidwa mwachindunji ku zida za MAX.
• Za kapangidwe ka MAX II example, sungani ma doko ndi ma CF + olumikizirana ndi ma GPIO oyenera. Kapangidwe kameneka kamagwiritsa ntchito pafupifupi 54% ya ma LE onse muchipangizo cha EPM240 ndipo amagwiritsa ntchito mapini 45 a I/O.
• Mapangidwe a MAX II example amagwiritsa ntchito chipangizo cha CF+, chomwe chimagwira ntchito m'njira ziwiri: PC Card ATA pogwiritsa ntchito I/O mode ndi PC Card ATA pogwiritsa ntchito kukumbukira. Njira yachitatu yosankha, mawonekedwe a True IDE, samaganiziridwa. Chipangizo cha MAX II chimagwira ntchito ngati woyang'anira alendo ndipo chimakhala ngati mlatho pakati pa wolandirayo ndi khadi la CF +.
