Iyo Star64 itsva RISC-V yakavakirwa single board komputa (SBC).
Nharaunda ye Pine64 yakaburitswa Mazuva mashoma apfuura, kuburikidza nechiziviso kuwanikwa kwe STAR64 single-board komputa, iyo inomira kunze kwekuvakwa neStarFive JH7110 quad-core processor (SiFive U74 1.5GHz) zvichibva paRISC-V zvivakwa uye ine maviri GbE LAN ports, imwe HDMI port, imwe PCIe slot, nezvimwe.
Iyo STAR64 Wiki peji inotsanangura kuti SBC iyi inofambiswa neStarFive JH7110 Quad-Core SiFive U74 64-bit (kusvika 1,5GHz) CPU uye Imagination Technology BX-4-32 GPU ine rutsigiro rweOpenCL 3.0, OpenGL ES 3.2, uye Vulkan 1.2.
Sezvatakambotaura pakutanga, Chinhu chinonakidza nezvebhodhi iri ndiyo RISC-V base, Kune avo vasina kujairana nekuvaka, iyi yemahara hardware Instruction Set Architecture (ISA) yakavakirwa paRISC (Yakaderedzwa Instruction Set) dhizaini.
Kusiyana nemaseti mazhinji emirairo, RISC-V's ndeyemahara uye yakavhurika uye inogona kushandiswa yehumambo-isina chero chinangwa, ichibvumira chero munhu kugadzira, kugadzira, uye kutengesa RISC-V machipisi uye software. Kunyange isiri yekutanga yakavhurika dhizaini ISA, yakakosha mukuti yakagadzirirwa kuve inobatsira pamhando dzakasiyana dzemidziyo. Iyo yekuraira seti zvakare ine yakakura muviri wekutsigira software, iyo inodzivirira kushaya simba kwakajairwa kwemaseti matsva ekuraira.
Kune chikamu che STAR64 zvinhu Zvinonzi bhodhi rakashongedzerwa ne:
- SoC: StarFive JH7110 ine
- CPU: Quad-core 64-bit RISC-V processor (SiFive U74: RV64GC) kusvika 1,5 GHz
- GPU: Imagination BXE-4-32 GPU @ inosvika mazana matanhatu MHz inotsigira OpenCL 600, OpenGL ES 3.0 uye Vulkan 3.2 graphics tekinoroji uye zvakare inotsigira GPU kuona kweanosvika masere maGPU, compression uye decompression algorithm On-Fly Frame Buffering (TFBC) uye tile Yakamisikidzwa inopa dhizaini yakavakirwa pa1.2D mifananidzo yebasa.

- 1080p30 H.265 Vhidhiyo Encoder
- System ndangariro: 4 GB kana 8 GB LPDDR4
- Kuchengetedza: MicroSD kadhi slot, kusvika ku128 GB eMMC flash module socket, 128 Mbit QSPI flash
Vhidhiyo kuburitsa - HDMI 2.0 chiteshi kusvika ku4Kp30 (maererano neWiki)
- 4-lane MIPI DSI yekubatanidza + touchpad yekubatanidza
- Kamera I / F: 4-lane MIPI CSI kamera yekubatanidza
- Kuteerera: 3,5mm audio jack
Nets - 2 Gigabit Ethernet RJ45 zviteshi
- Yakabatanidzwa Fn-Link RTL8852BU WiFi 6 uye Bluetooth 5.2 module uye 2 u.FL antenna yekubatanidza.
- USB: 1 USB 3.0 port, 3 USB 2.0 Type A ports, 2 USB 2.0 inopindirana kuburikidza nemusoro
Kuwedzera - 2-pini ruvara-coded "Pi40" GPIO musoro
- PCIe x4 slot ine PCIe 2.0 x1 interface
- Zvakasiyana-siyana: bhatani remagetsi, fan header, 3-pini UART/debug musoro, DIP switch yekumisikidza bhutsu (flash, SD, eMMC, UART)
- Power Supply: 12 VDC pa3 A kuburikidza ne-4-pini musoro kana simba resimbi yekubatanidza; WCRP pabhodhi
- Zviyero - 133 x 80mm
RISC-V inopa yakavhurika uye inochinjika yekuraira sisitimu yemuchina inobvumira mamicroprocessors kuvakirwa maapplication asingade pasina muripo kana kuisa mamiriro ekushandisa. RISC-V inogonesa kugadzirwa kweSoCs yakavhurika zvakakwana uye processors.
Parizvino, zvichibva pane zvakatemwa zveRISC-V, makambani akasiyana siyana nenharaunda dziri pasi pemarezinesi emahara akasiyana (BSD, MIT, Apache 2.0) vari kugadzira akawanda emhando dzakasiyana dzemicroprocessor cores, anopfuura zana maSoC uye akatogadzirwa machipisi. Tsigiro yeRISC-V yanga iripo kubva pakaburitswa Glibc 2.27, binutils 2.30, gcc 7, uye Linux kernel 4.15.
Finalmente Kune avo vanofarira kukwanisa kuziva zvakawanda nezve plaque pamwe nekuwana imwe yemhando dziripo, unogona kutarisa ruzivo, pamwe nekuwanikwa Mune inotevera chinongedzo.
Iyo Nyeredzi64 inowanikwa mune maviri akasiyana RAM magadzirirwo, ine 4 GB uye 8 GB ye RAM. Star64 Model-A SBC izvozvi pa PINE64 online store inogona kuwanikwa nemutengo we $69.99 USD ye 4 GB RAM modhi uye $89.99 USD ye8 GB RAM musiyano.
