Kompani Intel dhe AMD po zhvillojn\u00eb p\u00ebrbashk\u00ebt nj\u00eb grup t\u00eb zgjeruar komandash ChkTag (x86 Memory Tagging), i cili do t\u00eb standardizohet p\u00ebr nj\u00eb implementim t\u00eb unifikuar n\u00eb procesor\u00ebt x86 t\u00eb prodhuesve t\u00eb ndrysh\u00ebm. N\u00eb funksionalitetet e tij, ChkTag i ngjan zgjerimit MTE (MemTag), i cili tashm\u00eb \u00ebsht\u00eb i disponuesh\u00ebm n\u00eb procesor\u00ebt ARM, dhe gjithashtu ndihmon n\u00eb blokimin e shfryt\u00ebzimit t\u00eb dob\u00ebsive q\u00eb shkaktohen nga aksesimi i blloqeve t\u00eb memorie t\u00eb lira, mbipenges\u00ebs s\u00eb tamponit ose aksesimit t\u00eb memories para inicializimit. <\/p>\n
ChkTag ofron komanda t\u00eb reja procesori q\u00eb lejojn\u00eb n\u00eb nivel hardware t\u00eb lidhni etiketat me zona n\u00eb memorie dhe t\u00eb organizoni verifikimin e sakt\u00ebsis\u00eb s\u00eb p\u00ebrdorimit t\u00eb treguesve. \u00cbsht\u00eb th\u00ebn\u00eb se p\u00ebrdorimi i k\u00ebtyre komanda nga kompilator\u00ebt do t\u00eb mund\u00ebsoj\u00eb nj\u00eb pun\u00eb t\u00eb sigurt me memorien pa reduktuar performanc\u00ebn e aplikacioneve.

Metoda e mbrojtjes e realizuar reduktohet n\u00eb krijimin e nj\u00eb etike p\u00ebr secil\u00ebn bllok memorie, e cila sh\u00ebrben si nj\u00eb \u00e7el\u00ebs p\u00ebr qasje n\u00eb k\u00ebt\u00eb memorie (p\u00ebr shembull, n\u00eb implementimin e MTE, p\u00ebr \u00e7do 16 byte krijohet nj\u00eb etiket\u00eb 4-bit). Etiketa gjenerohet nga aplikacioni p\u00ebr zon\u00ebn e alokuar t\u00eb memories duke p\u00ebrdorur komanda speciale t\u00eb CPU, dhe pastaj ruhet n\u00eb bitat e lart\u00eb t\u00eb pap\u00ebrdorur t\u00eb treguesit, si dhe n\u00eb nj\u00eb zon\u00eb t\u00eb rezervuar dhe t\u00eb paaksesueshme p\u00ebr aplikacionet n\u00eb memorien lineare\/virtuale. Kur i qaset memories me nj\u00eb tregues t\u00eb etiketuar, procesori kontrollon p\u00ebrputhshm\u00ebrin\u00eb e etiketes t\u00eb lidhur me treguesin me etiketat e lidhura me blloqet e memories dhe lejon qasjen vet\u00ebm n\u00ebse etiketat p\u00ebrputhen. <\/p>\n
