Mtengo watsopano wa Raspberry Pi chifukwa cha kukwera kwa RAM

 

El Mtengo wa Raspberry Pi Silinso mtengo wosasinthika komanso wotsika mtengo womwe ambiri anali nawo m'maganizo. M'miyezi yaposachedwa, maziko a zikwangwani izi atsimikizira kuti kukwera kwa mitengo yonse zomwe zimakhudza makamaka mitundu yokhala ndi RAM yambiri, makamaka panthawi yomwe kufunikira kwa zida zopangira luntha lochita kupanga Zikukweza mtengo wa zinthu zina.

Kusintha kumeneku kukubwera pambuyo pa machenjezo angapo am'mbuyomu okhudza Kukwera kwa mtengo wa kukumbukira kwa DRAMIzi zikuphatikizapo kukumbukira kwa DDR4 ndi DDR5, komanso LPDDR4 yolumikizidwa muzipangizo. Chomwe poyamba chinkaganiziridwa ngati kusintha kwa mtengo kwakanthawi tsopano chakhala chokhazikika. kuwonjezeka kooneka bwino, ndi mitundu ina ya Raspberry Pi tsopano ikugwira ntchito pamitengo yosiyanasiyana komwe imapikisana ndi ma PC ang'onoang'ono a x86 omwe ndi otsika mtengo.

Kukumbukira kwa RAM kwakweza mtengo wa Raspberry Pi

Kuyambira pakati pa chaka cha 2025, mtengo wa chikumbutso cha RAM chapadziko lonse lapansi Zakhala zikukwera kotala ndi kotala. Zomwe zinayamba kukhudza ma module a DDR5 a ma PC ndi ma seva zatha kutsitsanso DDR4, komanso, kawirikawiri, gawo lililonse lomwe limaphatikiza DRAM. Ziwerengero zamakampani zikusonyeza kuti DDR5 ili panjira yoti ikwere mtengo kasanu. poyerekeza ndi milingo yam'mbuyomu, pomwe DDR4 yawonjezeka kale katatu m'mapangano ambiri ogulitsa zinthu zambiri.

Kusamvana kumeneku sikungokhudza dziko la makompyuta achikhalidwe okha. Kumakhudzanso zinthu monga ma laputopu, makadi ojambula zithunzi, ma consoles, ma notebook, ma TV, ndi makompyuta ang'onoang'ono a bolodi limodziEna mwa otsirizawa ndi Rasipiberi Pi, zomwe zimadalira gawo lalikulu la mtengo wawo pa LPDDR4 memory yomwe yasonkhanitsidwa pa bolodi. Zotsatira zake ndi zakuti Raspberry Pi yawona mtengo wake ukukwera ndi zoposa 70% m'mitundu ina., chithunzi chomwe chimasiyana ndi chithunzi cha chipangizo chotsika mtengo kwambiri chomwe chinali nacho mpaka pano.

Choyambitsa vutoli chikugwirizana kwambiri ndi kukwera kwa zomangamanga za luntha lochita kupangaMphamvu zambiri zopangira zinthu zokumbukira zikugwiritsidwa ntchito pazinthu zapamwamba kwambiri, monga Memory Yaikulu ya Bandwidth (HBM)Izi ndizofunikira kwambiri pa ma GPU ndi ma accelerator odzipereka a AI. Izi zimachepetsa kupezeka kwa mizere yopangira kukumbukira "kwachizolowezi" monga LPDDR4, zomwe zimapangitsa kuti pakhale kupezeka kochepa komanso mitengo yokwera mu unyolo wonse wopereka.

M'mawu angapo aposachedwa, Eben Upton, yemwe anayambitsa kampani ya Raspberry Pi, wavomereza kuti Zigawo zina zofunika kwambiri zawonjezeka kawiri mtengo Kwa kanthawi kochepa kwambiri, mazikowo anayesa kutenga gawo la ndalama zowonjezerazo, koma vutoli lakhala losakhazikika ndipo layenera kupereka ndalamazo kwa wogwiritsa ntchito, ndikusintha mtengo wa ma board malinga ndi kuchuluka kwa kukumbukira.

Momwe kukweza kumakonzedwera: RAM yambiri, ndalama zowonjezera zambiri

Ndi mitundu iti ya Raspberry Pi yomwe ikukwera mtengo komanso ndi iti yomwe ikupitirirabe kukhala chimodzimodzi

Kukwera kwa mitengo sikukhudzanso kabukhu konse mofanana. Bungweli lanena kuti kukweraku kukugwira ntchito makamaka kwa Raspberry Pi 4 ndi Raspberry Pi 5, kuwonjezera pa Kuwerengera Module 4 ndi 5, bola ngati izi zili ndi makonzedwe okhala ndi 2 GB ya RAM kapena kuposerapoNdemanga iyi ikuphatikizaponso makompyuta ang'onoang'ono okhala ndi makiyibodi ophatikizidwa. Raspberry Pi 500 ndi Raspberry Pi 500+, zomwe zili ndi maziko ofanana a LPDDR4 memory.

Mosiyana ndi zimenezi, pali zipangizo zomwe, pakadali pano, Amasunga mtengo wawo woyambirira.. The Raspberry Pi 4 ndi Raspberry Pi 5 zokhala ndi 1 GB yokha ya RAM Amasunga mitengo yawo yowerengera, yomwe ili pafupi $35 ndi $45 motsatanaMofananamo, Rasipiberi Pi 400Chitsanzo cha kale cha all-in-one chokhala ndi kiyibodi yolumikizidwa sichinakhudzidwe ndi kuwonjezeka kumeneku.

Gulu lina lomwe silikukhudzidwa ndi kukwera kwa mitengo ndi la mbale zomwe zimagwiritsa ntchito Kumbukumbu ya LPDDR2Apa ndi pomwe mitundu imakonda Raspberry Pi Zero, Raspberry Pi 3 ndi mitundu ina ya mibadwo yakaleMalinga ndi maziko enieniwo, akadali Ali ndi zinthu za LPDDR2 zomwe zasungidwa kwa zaka zingapo.Izi zimawathandiza kupitiriza kugulitsa ma board awa popanda kusintha mitengo kwakanthawi kochepa, popeza ukadaulo uwu sukumana ndi kukakamizidwa kofanana ndi kwa LPDDR4.

Izi zikutanthauza kuti iwo amene akufunafuna mtengo wotsika kwambiri womwe ungatheke pa ntchito zosavuta Akadali ndi malo mu gulu lakale. Ngakhale kuti sapereka magwiridwe antchito ofanana ndi a Raspberry Pi 4 ndi 5 aposachedwa, ma board okhala ndi LPDDR2 memory amakhalabe oyenera kugwiritsidwa ntchito monga ma seva ang'onoang'ono, automation yoyambira, kapena malo ophunzirira oyambira.

Chifukwa chake LPDDR2 siikukwera mtengo

Chinsinsi cha kusiyana kumeneku chili mu mtundu weniweni wa Memory ya LPDDR2 vs. LPDDR4Yoyamba imaonedwa kale ngati ukadaulo wakale wa mapulogalamu ambiri apamwamba, kotero siigwiritsidwa ntchito kwambiri pazinthu zapamwamba komanso zapamwamba. Malo akuluakulu osungira deta kapena zida zapamwamba zogwiritsa ntchito AI sizimagwiritsa ntchito kwambiri, ndipo izi zimapangitsa kuti zikhale zosavuta. mtengo wake wokhazikika poyerekeza ndi mitundu ina yamakono.

Mosiyana ndi zimenezi, ma layisensi aposachedwa monga Raspberry Pi 4, Raspberry Pi 5, Compute Module ya m'badwo wotsatira, ndi mndandanda wa Raspberry Pi 500 Akugwiritsa ntchito LPDDR4, mtundu weniweni wa memory womwe wakhala wokwera mtengo kwambiri chifukwa cha kufunikira kwamakono. Popeza maziko ali ndi Ma chips ambiri a LPDDR2Sikuyenera kupereka kukwera kwa mitengo kwa mitundu yomwe imagwiritsa ntchito, kotero ikhoza kupitiliza kuwapatsa ngati njira ina yotsika mtengo pomwe msika wa DRAM ukadali wovuta.

Kusiyana kumeneku kumapanga kabukhu ka ma speed awiri, momwe Ma motherboard amakono okhala ndi RAM yambiri ndi okwera mtengo kwambiri.Pakadali pano, mitundu yakale ikukhazikitsidwa ngati njira yotsika mtengo kwa iwo omwe safuna mphamvu zambiri kapena zinthu zapamwamba. Mwanjira yothandiza, ogwiritsa ntchito ambiri akuyamba kudzifunsa ngati, pa ntchito zina, imodzi mwa ma motherboard akale awa kapena zida zokonzedwanso sizingakwanire.

Kukwera kwa mitengo "kwakanthawi" ndi zomwe zingachitike

Pamene kusintha koyamba kwa mitengo kunalengezedwa kumapeto kwa chaka cha 2025, bungweli linalankhula poyera za Kukwera kwa mitengo kwakanthawi komwe kumalumikizidwa ndi msika wa RAMLingaliro linali lakuti, mitengo ya kukumbukira ikakhazikika, mitengo ya mamaboard ikhoza kubwezeretsedwa pamlingo wofanana ndi woyamba. Komabe, mitengo ya DRAM sinachedwe ndipo yakakamiza kukwera kwa mitengo kumayambiriro kwa chaka cha 2026.

M'mawu ake aposachedwa, Eben Upton akusunga kudzipereka kwake ku kuchepetsa mitengo yovomerezeka mwamsanga mtengo wa zigawo ukakhala wololezaNthawi yomweyo, akuvomereza kuti zomwe zikuchitika pano zimavuta kwambiri kuneneratu kulikonse kosangalatsa: popeza AI imagwiritsa ntchito gawo lalikulu la mphamvu zopangira ndipo opanga akuyang'ana kwambiri zinthu zapamwamba, Chaka cha 2026 chikukonzekera kukhala chaka chovuta pa chilichonse chomwe chimadalira kukumbukira kwachizolowezi.

Pakadali pano, chitsimikizo chokha ndi mitengo yatsopano ndi chenjezo lomwe Zosintha zina sizingathetsedwe Ngati DRAM ikupitiliza kukwera mtengo, kuthekera kulipobe kuti, msika ukakhazikika, kuwonjezeka kumeneku kungasinthe pang'ono kapena kwathunthu, ngakhale kuti palibe nthawi yodziwika bwino. Kwa ogwiritsa ntchito aku Europe, izi zikutanthauza nthawi yoganizira mosamala, komwe kuli bwino kuwunika mosamala mtundu uti ndi kuchuluka kwa RAM komwe kuli kofunikira pa projekiti iliyonse musanagule.

Mu malo atsopanowa, Raspberry Pi ikadali nsanja yosinthika, koma siilinso yotsika mtengo monga kale. Omwe amafunikira magwiridwe antchito apamwamba komanso kukumbukira kwakukulu ayenera kuganizira za mitengo yokwera. mitengo yokwera kwambiriPakadali pano, anthu omwe ali ndi ntchito zosavuta amatha kupitiliza kugwiritsa ntchito ma board okhala ndi ma LPDDR2 kapena 1GB configuration, omwe sakhala osasinthika. Bola RAM ikapitilizabe kulamulira msika, pulojekiti iliyonse ya Raspberry Pi ku Spain kapena ku Europe idzafunika kuwerengera mosamala kwambiri komanso kufananiza bwino njira zina kuposa zaka zam'mbuyomu.
