Kunyangwe Apple ichangobva kuratidza maM2 machipi, zvinofanirwa kuverengerwa kuti izvo zviripo pamusika ndezvapfuura. Iyo M1 chip iri kupa mhedzisiro yakanaka kudaro uye yave imwe yematombo emakona ezvakanakisa Apple zvishandiso: Macs.. Gare gare yakawedzerwa kune iyo iPad, asi chinonyanya kukosha ndechekuita kwayo, kugona mumakomputa eAmerican company. . Yakasimbiswawo sechipi iyo kuchengetedzwa kwayo kwakaedzwa uye kwakawedzerwa. Nekudaro, tichiziva kuti 100% chengetedzo haipo, isu takatokwanisa kutyora chip. Zvaitwa nekuda kwePACMAN.
Pasi pemamiriro akakwana uye kudzidza kwakadzama, iyo Computer Science uye Artificial Intelligence Laboratory (CSAIL) ye with, yakawana chikanganiso muApple's M1 chip.
Kuburikidza nekurwiswa kwakasanganiswa kwakanzi PACMAN, zvave zvichiita kukunda chengetedzo yakaisirwa neApple pane aya machipisi. Avo vakareva kutanga kwekuchinja kweApple kuhupenyu hutsva pasina Intel.
Iko kukanganisa kunoitwa PACMAN kunowanikwa mu pointer authentication code (PAC) iyo isiri chinhu chinopfuura nzira yekuchengetedza iyo inodzivirira sisitimu kubva mukurwiswa, kurasikirwa uye nekurangarira huwori hurema.
Dambudziko nekusagadzikana kwekuchengetedza uku nderekuti haigone kugadzirwa nesoftware, nokuti kurwisa, sezvatataura, kwakasanganiswa. Iyo inosanganisa huwori hwekurangarira pamwe nekusarudzika kuuraya kurwiswa kunzvenga pointer yekusimbisa makodhi.
Kuuraya kwakadai kana kufungidzira kunowanzo shandiswa nema processor kuvandudza mashandiro. Ivo vari kufungidzira kana kufungidzira mitsetse yekodhi yavanofanirwa kugadzirisa. Nepo pointer authentication iri cryptographic siginecha inosimbisa kana application ine hutachiona. Nenzira iyi, PACMAN inotora mukana wekufungidzira uku kufungidzira iyo kodhi.
Joseph Ravichandran, munyori pamwe chete weongororo iyi akati: “kutendeseka kwepointer senzira yekupedzisira yekudzivirira kwete semhedziso sezvataimbofunga kuti ndizvo".
Chinhu chine ngozi ndechekuti zvaigona inokanganisa machipisi ese ane ArM architecture, saka M2 inogona kukanganiswa.
