🥇 Linux Foundation waxay ka shaqayn doontaa chips il furan

Mu'asasada Linux waxay bilawday jiho cusub - Isbahaysiga CHIPS. Iyada oo qayb ka ah mashruucan, ururku wuxuu horumarin doonaa nidaamka waxbarida RISC-V ee bilaashka ah iyo teknoolojiyadda abuurista soo-saareyaal ku saleysan. Aan si faahfaahsan kuugu sheegno waxa ka dhacaya goobtan.

Maxaa keenay Isbahaysiga CHIPS?

Xirmooyinka ka ilaaliya Meltdown iyo Specter, xaaladaha qaarkood hoos u dhigida wax soo saarka server-yada 50%. Isla mar ahaantaana, kala duwanaansho cusub oo dayacan oo la xidhiidha fulinta amarrada mala-awaalka ah ayaa wali soo baxaya. Ku saabsan mid iyaga ka mid ah ayaa la ogaaday horraantii Maarso - Khabiirada amniga macluumaadka waxay ku magacawday Spoiler. Xaaladani waxay saamaysaa dood baahida loo qabo in dib loo eego xalalka hardware ee jira iyo hababka horumarkooda. Gaar ahaan, Intel mar hore ayay isu diyaarinayaan naqshad cusub oo loogu talagalay soo-saarayaasheeda, oo aan hoos imanayn Meltdown iyo Specter.

Aasaaska Linux midkoodna dhinac ma istaagin. Ururku waxa uu bilaabay hindise isaga u gaar ah, CHIPS Alliance, oo xubnahooda ay horumarin doonaan soo-saareyaal ku salaysan RISC-V.

Maxaa mashruucyo ah oo hore loo soo saaray?

Xubnaha CHIPS Alliance waxaa ka mid ah Google, Western Digital (WD) iyo SiFive. Mid kasta oo iyaga ka mid ah ayaa soo bandhigay horumarkooda. Aynu ka hadalno qaarkood.

RISCV-DV

Kooxda raadinta IT-ga ayaa soo saartay madal lagu tijaabiyo soo-saareyaal ku saleysan RISC-V si ay u furto ilo. xal random soo saara kooxaha in u oggolow hubi shaqada qalabku leeyahay: tijaabi hababka kala-guurka, xidhmooyinka wacitaanka, CSR- diiwangelinta, iwm.

Tusaale ahaan, Tani waa sida uu fasalku u eg yahaymas'uul ka ah samaynta imtixaan fudud ee tilmaamaha xisaabta:

class riscv_arithmetic_basic_test extends riscv_instr_base_test;

  `uvm_component_utils(riscv_arithmetic_basic_test)
  `uvm_component_new

  virtual function void randomize_cfg();
    cfg.instr_cnt = 10000;
    cfg.num_of_sub_program = 0;
    cfg.no_fence = 1;
    cfg.no_data_page = 1'b1;
    cfg.no_branch_jump = 1'b1;
    `DV_CHECK_RANDOMIZE_WITH_FATAL(cfg,
                                   init_privileged_mode == MACHINE_MODE;
                                   max_nested_loop == 0;)
    `uvm_info(`gfn, $sformatf("riscv_instr_gen_config is randomized:n%0s",
                    cfg.sprint()), UVM_LOW)
  endfunction

endclass

By sida laga soo xigtay horumarinta, madal ka duwan analogues ay in ay ogolaato in tijaabinta isku xigxiga ee dhammaan qaybaha chip, oo ay ku jiraan block xusuusta.

OmniXtend borotokoolka

Kani waa borotokoolka shabakada WD kaas oo bixiya kaydinta isku xidhka Ethernet. OmniXtend Waxay kuu ogolaanaysaa inaad si toos ah farriimaha ku dhaafsato khasnadda processor-ka waxaana loo isticmaalaa in lagu xidho noocyada kala duwan ee xawaaraha: GPU ama FPGA. Waxa kale oo ay ku habboon tahay abuurista nidaamyo ku salaysan jajabyo badan oo RISC-V ah.

Hab-maamuuska mar hore waa la taageeray Chips SweRVku jihaysan habaynta xogta xarumaha xogta. SweRV waa 32-bit, dual-pipeline superscalar processor oo lagu dhisay tignoolajiyada habka 28nm. Dhuun kastaa waxay leedahay sagaal heerar, taas oo suurtogal ka dhigaysa in la raro lana fuliyo amarro badan isku mar. Qalabku wuxuu ku shaqeeyaa inta jeer ee 1,8 GHz.

Generator Chip Gantaalka

Xalku wuxuu ka yimid SiFive, kaas oo ay aasaaseen soo-saareyaasha tignoolajiyada RISC-V. Chip Gantaal waa koronto dhaliye xudunta u ah processor-ka RISC-V ee luuqada Chisel. Isaga waa a Maktabadaha la jaan-qaadaya ee loo isticmaalo abuurista SoC.

Marka la eego Chisel, ka dibna waa luqad sifayn hardware ku salaysan Scala. Waxay soo saartaa koodka Verilog oo hooseeya подходит si loogu habeeyo ASIC iyo FPGA. Markaa, waxay kuu ogolaanaysaa inaad isticmaasho mabaadi'da OOP marka aad horumarinayso RTL.

Rajada Alliance

Khubarada ayaa sheegay in hindisaha Linux Foundation uu ka dhigi doono processor-ka suuqa mid dimuqraadi ah oo u furan ciyaartoy cusub. Marka loo eego IDC dabaaldegin caannimada sii kordheysa ee mashaariicda noocan oo kale ah ay saameyn togan ku yeelan doonto horumarinta tignoolajiyada barashada mashiinka iyo nidaamyada AI guud ahaan.

Horumarinta soo-saareyaal il furan ayaa sidoo kale hoos u dhigi doona qiimaha naqshadeynta chips-ka caadiga ah. Si kastaba ha noqotee, tani waxay dhici doontaa oo keliya haddii bulshada Linux Foundation ay maamusho inay soo jiidato horumariyayaal ku filan.

Mashaariic la mid ah

Ururada kale waxay sidoo kale horumarinayaan mashaariicda la xidhiidha qalabka furan. Tusaale waxaa ah daladda CXL, oo soo bandhigtay heerka Compute Express Link badhtamihii bishii Maarso. Farsamadu waxay la mid tahay OmniXtend waxayna sidoo kale isku xirtaa CPU, GPU, FPGA. Xog-isweydaarsiga, halbeeggu wuxuu isticmaalaa baska PCIe 5.0.

Mashruuc kale oo loogu talagalay horumarinta tignoolajiyada processor-ka waa MIPS Open, kaas oo soo muuqday Disembar 2018. Hindisaha waxaa sameeyay xisaabinta Wave Computing. Horumarinta ayaa qorsheynaya furan Helitaanka amarrada MIPS ee ugu dambeeyay ee 32- iyo 64-bit ee bulshada IT-ga. Bilawga mashruuca filayay bilaha soo socda.

Guud ahaan, habka isha furan wuxuu noqonayaa mid guud ahaan la aqbali karo maaha oo kaliya software, laakiin sidoo kale qalabka. Mashaariicda noocaan ah waxaa taageera shirkado waaweyn. Sidaa darteed, waxaan filan karnaa in mustaqbalka dhow qalabyo badan oo ku salaysan heerarka qalabka furan ay ka soo muuqan doonaan suuqa.
