Sida ay sheegayaan wararkii ugu dambeeyay koox cilmi-baarayaal ah oo ka tirsan jaamacadda Michigan ee dalka Mareykanka ayaa dhawaan sheegtay inay ku guuleysteen inay soo saaraan processor-kii ugu horreeyay ee aan la jabsan karin oo lagu magacaabo MORPHEUS.
Processor-kan cusub, ee aan la jabsan karin ayaa si degdeg ah u fulin kara hawlgallada sirta xogta si ay algorithms-kiisu u beddelaan si ka dhakhso badan marka loo eego kuwa jabsada; Sidaa darteed, waxay bixisaa ammaan aad uga weyn marka loo eego hababka difaaca ee soo-saareyaasha hadda.
La kulan processor-ka ugu horreeya adduunka ee aan la jabsan karin
Koox cilmi-baarayaal ah oo ka tirsan Jaamacadda Michigan ee dalka Mareykanka ayaa sheegtay in ay sameeyeen processor-kii ugu horreeyay ee aan la jabsan karin oo lagu magacaabo MORPHEUS.
Processor-kan cusub, ee aan la jabsan karin ayaa si degdeg ah u fulin kara hawlgallada sirta xogta si ay algorithms-kiisu u beddelaan si ka dhakhso badan marka loo eego kuwa jabsada; Sidaa darteed, waxay bixisaa ammaan aad uga weyn marka loo eego hababka difaaca ee soo-saareyaasha hadda.
Haddii wax ay soo bixi karaan, sannadkii hore 2018 waxay ahayd tirada badan ee dayacanka halista ah ee laga helay processor-yada. AMD gaar ahaan Intel . Cillaadaha la yaqaan sida Meltdown, Specter iyo, dhawaanahan, PortSmash iyo SPOILER ayaa cilmi-baarayaasha labada shirkadood ku kaxaystay isku daygii ay ku xallin lahaayeen.
Si kastaba ha ahaatee, koox saynisyahano ah oo ka socda Jaamacadda Michigan, oo ay hogaaminayaan Todd Austin , naqshadiisa cusub ee Processor-rada, oo lagu magacaabo MORPHEUS, oo awood u leh inay iska caabiyaan weerarrada lagu soo qaado Processor-ka aaladaha ay ku rakiban yihiin.
Taas awgeed, processor-ku waxa uu si buuxda oo aan kala sooc lahayn u beddeli karaa qaybo ka mid ah qaab-dhismeedkiisa si aanay weligood weeraryahannadu u ogaanin waxa ay isku dayayaan in ay helaan. Laakiin tan ugu muhiimsan, Morpheus wuxuu u qaban karaa shaqada si degdeg ah iyo isticmaalka kheyraad hooseeya.
Furaha amnigu waa in processor-ka cusub ee MORPHEUS uu rabo inuu bixiyo "hab-bixinta habraaca" ama hawlgallada koodka qaarkood ee loo yaqaan "semantics undefined". Qaybtani waxay si fudud u tilmaamaysaa goobta, cabbirka, iyo waxa ku jira astaanta barnaamijka.
Sidaa darteed, haddii uu weeraryahanku rabo inuu isticmaalo xogtan, taas oo inta badan go'an, haddii xaalad kastaa jirto, ma awoodi doono inuu si joogto ah u helo, sababtoo ah ka dib 50 millise seconds, waxay u beddeli doonaan qiyam kale. Heerka dib u dalbashada koodka ayaa dhowr jeer ka sarreeya Farsamooyinka jabsiga ugu casrisan uguna awooda badan maanta loo isticmaalo processor-yada hadda jira.
Nashqada MORPHEUS, si loo caddeeyo, waxaa lagu rakibay processor-ka RISC-V, jajab il furan oo si weyn loogu isticmaalo horumarinta "prototyping". Processor-kan, MORPHEUS waa la weeraray "Control-qulqul" Waa mid ka mid ah hababka ugu daran ee uu isticmaalo jabsada Adduunka. Waxayna ku guulaysatay inay ka gudubto dhammaan siddooyinkii lagu fuliyay guul dhammaystiran.
Sidoo kale akhri: Sida loo hubiyo xawaaraha processor-ku u ordi karo
Sida la filayo, saamiga koodhka naqshadaha processor-ka daciifka ah ayaa kharash ku leh ilaha nidaamka. Si kastaba ha ahaatee, saynisyahannadu waxay soo saareen MORPHEUS waxayna ku andacoodeen in kharashka caawimadani yahay 1% oo keliya, iyo xawaaraha uu code-ku noqdo random wuu kala duwanaan karaa, iyadoo ku xidhan ujeedada loo isticmaalayo processor-ka.
Tan waxa kale oo ka mid ah aaladaha weerarka, kaas oo falanqeeya goorta uu qofku dhici karo oo xawaareynaya iyadoo lagu salaynayo xogtan.
