Zolakwika Zazikulu 17: Mabasi awa onse amakokedwa ndi kukana, motero ndimakhala wopumira.
Yankho labwino: Pali zifukwa zambiri zomwe zikutanthauza kuti zizindikiro zimafunikira kukokedwa ndi pansi, koma si onse omwe ayenera kukokedwa. Kukoka ndi kukoka-pansi kumakoka chizindikiro chosavuta, ndipo zomwe zilipo ndizochepera kuposa microampes, koma chizindikiro choyendetsedwa ndi chiwonetsero chakokedwa, zomwe zikuchitika zomwe zimafika ku Milliamp. Dongosolo lapano nthawi zambiri limakhala ndi zidutswa 32 zilizonse, ndipo pakhoza kukhala ngati kabati wina ndi zigawo zina zam'madzi kuti mugwiritse ntchito ma afwatt ochepa, chifukwa chake.
Vuto Lodziwika 18: Dongosolo lathu limathandizidwa ndi 220V, kotero sitifunikira kusamalira mowa wamphamvu.
Njira yabwino: Kamangidwe kambiri si kokha chifukwa chopulumutsa mphamvu, komanso pochepetsa mtengo wa ma module a mphamvu ndi njira zozizira, ndikuchepetsa phokoso la magetsi chifukwa cha kuchepetsa kwaposachedwa. Pamene kutentha kwa chipangizocho kumachepa, moyo wa chipangizocho umakulitsidwa (kutentha kwa chipangizo cha semiconductor kumawonjezeka ndi madigiri 10, ndipo moyo wafupikitsidwa ndi theka). Mphamvu yamagetsi iyenera kuganiziridwa nthawi iliyonse.
Vuto Lodziwika 19: Mphamvu zamphamvu zoterezi ndizotsika kwambiri, osadandaula nazo.
Yankho labwino: Ndikovuta kudziwa kumwa kwa mphamvu mkati mwazinthu zomwe zingachitike. Zimatsimikiziridwa ndi zomwe zili pa pini. ABT162444 imadya osakwana 1 ma (osakhala ndi katundu, koma chizindikiro chake ndi pini iliyonse. Itha kuyendetsa katundu wa 60 ma (monga kufananitsa kukana kwa ohms), ndiye kuti, kumwa kwambiri mphamvu ya katundu wathunthu kumatha kufikira 60 * 16 = 960ma. Zachidziwikire, mphamvu zongopereka zomwe zilipo zokulirapo, ndipo kutentha kumagwera katundu.
Zovuta 20: Momwe mungathanirane ndi izi zomwe zagwiritsidwa ntchito ndi zomwe / o / o / o / o / fpga ndi FPGA? Mutha kumusiya wopanda kanthu ndikuyankhula za izi pambuyo pake.
Njira yabwino: Ngati madoko osagwiritsidwa ntchito ai / o / o / o / o / o itha kukhala osakanikirana pang'ono ndi zida zakunja Ngati yatulutsidwa, pini iliyonse idzakhalanso ndi microalpenti yaposachedwa, kotero njira yabwino ndikuyiyika ngati kutulutsa (mwakutero, palibe zizindikilo zina zomwe zingalumikizidwe ndi kunja).
Zolakwika 21: Pali zitseko zambiri zomwe zatsala pa FPGA iyi, kuti mutha kuzigwiritsa ntchito.
Njira yabwino: Kugwiritsa ntchito mphamvu kwa FGU ndikogawana ndi kuchuluka kwa zithunzi zogwiritsidwa ntchito ndi kuchuluka kwa ma flips omwe amagwiritsidwa ntchito, kotero kumwa kwa mphamvu ya FPGA mosiyanasiyana ndi nthawi zosiyanasiyana kumatha kukhala kosiyana. Kuchepetsa kuchuluka kwa ma flip-flops ojambulidwa kwambiri ndi njira yofunika kwambiri yochepetsera kugwiritsa ntchito magetsi a FPGA.
Vutoli 22: Memory ili ndi zizindikiro zambiri zowongolera. Gulu langa limangofunika kugwiritsa ntchito oe ndipo sitikuwonetsa. Chosankha cha chip iyenera kukhalabe pansi, kotero kuti deta imatuluka mwachangu panthawi yowerengera.
Njira yabwino: Kugwiritsa ntchito mphamvu kwambiri pokumbukira zomwe zip zip ndi koyenera (mosasamala za oe ndipo ife) zidzakhala zoposa 100 nthawi yomwe Chip sizabwino. Chifukwa chake, CS iyenera kugwiritsidwa ntchito kuwongolera chip monga momwe tingathere, ndipo zofunikira zina ziyenera kukwaniritsidwa. Ndikotheka kufupikitsa m'lifupi mwake la chip.
Zovuta Zazikulu 23: Kuchepetsa kugwiritsa ntchito mphamvu zamagetsi ndi ntchito ya ogwira ntchito kwa hardware, ndipo alibe chochita ndi mapulogalamu.
Yankho labwino: Hardware ndi gawo chabe, koma pulogalamuyi ndi wochita seweroli. Kufikira pafupifupi pachip chilichonse pabasi ndipo kufinya kwa chizindikiro chilichonse kumayendetsedwa ndi pulogalamuyo. Ngati pulogalamuyo imatha kuchepetsa kuchuluka kwa kukumbukira kwakunja (pogwiritsa ntchito zosintha zambiri zakunja, kugwiritsa ntchito cache yamkati) Kuti bolodi itembenukire bwino, harvare ndi mapulogalamu ayenera kudyetsedwa ndi manja onse awiri!
Vuto Labwino 24: Chifukwa chiyani zizindikirozi zikuwononga? Malingana ngati machesi ndi abwino, atha kuchotsedwa.
Yankho labwino: Kupatula pazizindikiro zingapo (monga 100base-t, cml), pali oversi. Malingana ngati siikulu kwambiri, siyifunikira kufanana. Ngakhale zitakhala zikufanana, sizitanthauza zabwino kwambiri. Mwachitsanzo, kusamvana kwa TTL kumakhala kochepera 50 ohms, ndipo ena 20 ohms. Ngati kukana kwakukulu kotereku kumagwiritsidwa ntchito, komweko kudzakhala kwakukulu kwambiri, mphamvu yamagetsi idzakhala yosavomerezeka, ndipo matalikidwe akuwonetsa adzakhala ochepa kwambiri kuti agwiritsidwe ntchito. Kupatula apo, kusamvana kwa chizindikiritso chachikulu mukatulutsa mulingo wautali komanso kutulutsa mulingo wotsika siyofanana, ndipo ndizothekanso kukwaniritsa zofananira. Chifukwa chake, zofananira za TTL, LVDs, 422 ndi zizindikilo zina zitha kukhala zovomerezeka malinga ngati oversiot akwaniritsidwa.
