Kolm ja pool aastat p\u00e4rast s\u00fcsteemi loomisel<\/a><\/noindex> Raspberry Pi 3 Raspberry Pi Foundation esituse<\/a><\/noindex> uue p\u00f5lvkonna plaate Raspberry Pi 4<\/a><\/noindex>. Tellimuseks on n\u00fc\u00fcd saadaval mudel «B», varustatud<\/a><\/noindex> uuendatud SoC BCM2711, mis on t\u00e4ielikult \u00fcmber t\u00f6\u00f6tatud versioon eelnevalt kasutatud SoC-st BCM283X, toodetud 28 nm protsessiga. Plaadi hind on endiselt 35 USA dollarit. <\/p>\n

SoC sisaldab endiselt nelja 64-bitist ARMv8 tuuma ja t\u00f6\u00f6tab vaid veidi suurendatud sagedusel (1,5 GHz asemel 1,4 GHz). Protsessimuudatus v\u00f5imaldas asendada Cortex-A53 v\u00f5imekaima Cortex-A72 tuumaga, mis t\u00f5stis j\u00f5udlust uuele tasemele. Samuti on \u00fcleminek LPDDR4 m\u00e4lu kasutamisele, mis tagab kolmekordse ribalaiuse suurenemise v\u00f5rreldes varem kasutatud LPDDR2 m\u00e4luga. Tulemuseks on see, et uue plaadi tulemuslikkus \u00fcletab eelmist mudelit Raspberry Pi 3B+ 2-4 korda.<\/p>\n

Teistest olulistest erinevustest v\u00f5ib m\u00e4rkida, et kontrollereid t\u00e4iendab PCI Express, kaks USB 3.0 pesad (pluss kaks USB 2.0) ja kaks Micro HDMI porti (varem oli \u00fcks t\u00e4issuuruses HDMI), mis v\u00f5imaldavad kuvada pilti kahel 4K kvaliteediga monitoril. Oluliselt uuendatud on VideoCore VI graafikakiip, mis toetab OpenGL ES 3.0 ja suudab dekodeerida H.265 videot 4Kp60 (v\u00f5i 4Kp30 kahel monitoril). Toide v\u00f5ib tulla USB-C pordi kaudu (varem kasutati USB micro-B), l\u00e4bi GPIO v\u00f5i lisavarustuse mooduli<\/a><\/noindex> PoE HAT (Power over Ethernet).<\/p>\n

Lisaks on lahendatud pikaajaline probleem m\u00e4lu suurusega \u2014 n\u00fc\u00fcd on plaat saadaval variantidega 1, 2 ja 4 GB RAM (vastavalt $35, $45 ja $55), mis teeb uue plaadi sobivaks lahenduseks t\u00f6\u00f6jaamade, m\u00e4nguplatvormide, serverite, nutikodu v\u00e4ravate, robootika juhtimisseadmete ja kaasaegsete multimeedia s\u00fcsteemide loomiseks. <\/p>\n

T\u00e4iustatud gigabiti Ethernet-kontroller, mis on n\u00fc\u00fcd \u00fchendatud SoC-iga eraldi RGMII bussiga, v\u00f5imaldades saavutada t\u00e4it lubatud j\u00f5udlust. USB on n\u00fc\u00fcd realiseeritud eraldi VLI kontrolleri kaudu, mis on \u00fchendatud PCI Expressiga ja tagab kogumahutavuse 4 Gbps. Nagu varem, on kaardil 40 GPIO-porti, DSI (puutetundliku ekraani \u00fchendamine), CSI (kaamera \u00fchendamine) ja traadita suhtlemise kiip, mis toetab 802.11ac standardit, t\u00f6\u00f6tades sagedustel 2.4GHz ja 5GHz ning Bluetooth 5.0.<\/p>\n

Samaaegselt ilmus uus v\u00e4ljaanne distributiivist Raspbian<\/a><\/noindex>, millel on t\u00e4ielik tugi Raspberry Pi 4-le. V\u00e4ljalase on samuti t\u00e4helepanuv\u00e4\u00e4rne, kuna on \u00fclemineku Debian 10 «Buster» paketip\u00f5hisusele (varasemalt kasutati Debian 9), samuti m\u00e4rkimisv\u00e4\u00e4rne kasutajaliidese \u00fclevaatus ja uue Mesa V3D draiveri kasutuselev\u00f5tt, mis pakub oluliselt paremat 3D tuge (sealhulgas v\u00f5imaluse kasutada OpenGL brauseri kiirendamiseks). Kaks versiooni on allalaadimiseks valmistatud \u2014 l\u00fchendatud (406 MB<\/a><\/noindex>) serveris\u00fcsteemidele ja t\u00e4isversioon (1.1 GB<\/a><\/noindex>), mis on varustatud kasutajakeskkonnaga PIXEL<\/a><\/noindex> (LXDE haru). Paigaldamiseks on saadaval reposiitoreid<\/a><\/noindex> saadaval on umbes 35 000 paketti. <\/p>\n
