Saka, kana iwe uchida 66 x 8 FIFO, inogona kunge iri advan yakawandatageous kusarudza kudzika kweFIFO kwe64 kana 128 kana nzvimbo uye/kana kumhanya kuri kunetseka.
3 Zvirongwa zveNguva
Nyora Operation
Munguva yekunyora basa kana WE sign yakasimbiswa iyo FIFO inochengeta kukosha paDATA bhazi mundangariro. Chiratidzo cheWACK chinomisikidzwa pese pese pakaitika basa rekunyora rakabudirira paFIFO. Kana iyo FIFO ikazadza, iyo FULL mureza inosimbiswa zvichiratidza kuti hapana imwe data inogona kunyorwa. Mureza we AFULL unomisikidzwa kana huwandu hwezvinhu muFIFO hwakaenzana nehuwandu hwepakati. Kana basa rekunyora rikaedzwa apo FIFO yakazara, chiratidzo cheOVERFLOW chinosimbiswa pawachi inotevera, zvichiratidza kuti kukanganisa kwaitika. Iyo OVERFLOW siginecha inosimbiswa kune yega yega basa rekunyora rinotadza. A sampdhiyagiramu yenguva yeFIFO ine kudzika kwekugadzirisa kwe4, inenge yakazara kukosha yakaiswa ku3, uye kusimuka kwewachi kunoratidzwa muMufananidzo 3-1.
Verenga Operation
Munguva yekuverenga mashandiro apo chiratidzo cheRE chakasimbiswa FIFO inoverenga kukosha kwedata mubhazi reQ kubva mundangariro. Iyo data inowanikwa kune mutengi mawachi maviri mushure mekutaura kweRE, iyi data inobatwa mubhazi kusvika iyo RE inotevera yasimbiswa. Chiratidzo cheDVLD chinosimbiswa pawachi imwechete iyo data iripo. Naizvozvo, iyo mutengi logic inogona kutarisa iyo DVLD chiratidzo chechiratidzo che data rakakodzera. Nekudaro, DVLD inongotsigira yekutanga wachi kuti data nyowani iripo, nepo iyo chaiyo data inogona kunge ichiri mubhazi redata. Kana iyo FIFO ikabviswa ipapo iyo EMPTY mureza inosimbiswa kuratidza kuti hapasisina data data inogona kuverengwa. Mureza we AEMPTY unotaurwa kana huwandu hwezvinhu muFIFO hwaenzana nechiyero chakatarwa. Kana oparesheni yekuverenga ikaedzwa apo FIFO isina chinhu, iyo UNDERFLOW siginecha inomisikidzwa pawachi inotevera inoratidza kuti kukanganisa kwaitika. Iyo UNDERFLOW siginecha inosimbiswa kune yega yega yekuverenga oparesheni inotadza.
A sampdhayagiramu yenguva yeFIFO ine kudzika kwekugadzirisa kwe4, inenge isina chinhu yakakosha yakaiswa ku1, uye kusimuka kwewachi kunoratidzwa muMufananidzo 3-2.
Mashandiro ane Variable Aspect Ratio
FIFO ine upamhi hwakasiyana-siyana ine kudzika kwakasiyana uye hupamhi masisitimu echikamu chekunyora nekuverenga. Pane zvimwe zvakakosha zvinotariswa kana uchishandisa rudzi urwu rweFIFO:
Kurongeka kwedata - Rutivi rwekunyora rune hupamhi hudiki pane Rutivi Rwekuverenga: Iyo FIFO inotanga kunyora kune chikamu chidiki chakakosha chendangariro kumusoro. (tarisa dhayagiramu yenguva iri pazasi)
- Kurongeka kwedata - Rutivi rweKunyora rune hupamhi hukuru kupfuura Rutivi Rwekuverenga, kureva kuti FIFO inotanga kuverenga kubva pachikamu chidiki chakakosha chendangariro. Zvinoreva kana izwi rekutanga muchikamu chekunyora riri 0xABCD, mazwi akaverengwa kubva muFIFO anenge ari 0xCD achiteverwa ne0xAB.
- Kugadzirwa kwemureza wakazara - Iyo FULL inotsinhirwa kana izwi rakazara kubva mumaonero ekunyora risingagoni kunyorwa mukati. ZVAKAZARA zvinoramba chete kana paine nzvimbo yakakwana muFIFO yekunyora izwi rakazara kubva muchikamu chekunyora. (ona dhayagiramu yenguva iri mumufananidzo 3-3)
- Empty mureza kugadzirwa - Iyo EMPTY inobviswa chete kana izwi rakazara kubva pakuverenga chikamu reshiyo rinogona kuverengwa kunze. EMPTY inosimbiswa kana FIFO isina izwi rakazara kubva pakuverenga chikamu chechiyero (tarisa kudhayagiramu yenguva iri Mufananidzo 3-3).
- Chirevo chechimiro chemureza wechizvarwa ndechekuti zvinogoneka kuve nezwi risingaverengeki muFIFO risingagone kuoneka pakarepo padivi rekuverenga. For example, funga kana chikamu chekunyora chine hupamhi hudiki pane chikamu chekuverenga. Divi rekunyora rinonyora izwi rimwe chete uye rinopedzisa. Mune iyi mhando yemamiriro ezvinhu, chishandiso chinoshandisa iyo FIFO chinofanira kufunga kuti izwi redata rechidimbu rinomiririrei.
- Kana izwi re data rechidimbu risingakwanisi kugadziriswa pasi pemvura pane zvisingabatsiri kuribvisa muFIFO kusvika rasvika pashoko rakazara. Nekudaro, kana izwi rechidimbu richionekwa serinoshanda uye richikwanisa kugadziridzwa kudzika pasi mune yaro 'isina kukwana', saka imwe mhando yemaitiro inoda kugadzirwa kubata ichi chimiro.
Mufananidzo 3-3 unoratidza mamiriro ekuti chikamu chekunyora chinogadziriswa chine x4 hupamhi uye rutivi rwekuverenga se x8 upamhi.
