Iqela labaphandi bezokhuseleko kwiqela le-uCode lipapashe ikhowudi yomthombo wokucima i-Intel microcode. Indlela yokuvula okuBomvu, ephuhliswe ngabaphandi abafanayo ngo-2020, inokusetyenziselwa ukukhupha i-microcode efihliweyo. Ikhono elicetywayo lokukhupha i-microcode likuvumela ukuba uhlolisise isakhiwo sangaphakathi se-microcode kunye neendlela zokuphumeza imiyalelo yomatshini we-x86. Ukongezelela, abaphandi babuyisela ifomathi yokuhlaziywa kwe-microcode, i-algorithm ye-encryption kunye nesitshixo esisetyenziselwa ukukhusela i-microcode (RC4).
Ukumisela isitshixo soguqulelo oluntsonkothileyo esisetyenzisiweyo, ubuthathaka kwi-Intel TXE yasetyenziswa, apho bakwazile ukusebenzisa imowudi yokulungisa engabhalwanga, abathi abaphandi bayibize ngegama elithi βRed Unlock.β Kwimo ye-debug, sakwazi ukukhuphela ukulahla nge-microcode esebenzayo ngokuthe ngqo kwi-CPU kwaye sikhuphe i-algorithm kunye nezitshixo kuyo.
I-toolkit ikuvumela kuphela ukuba uguqule i-microcode, kodwa ayikuvumeli ukuba uyitshintshe, ekubeni ingqibelelo ye-microcode iqinisekiswa ngakumbi kusetyenziswa isiginitsha yedijithali esekelwe kwi-algorithm ye-RSA. Indlela iyasebenza kwiiprosesa ze-Intel Gemini Lake ezisekwe kwi-Goldmont Plus microarchitecture kunye ne-Intel Apolo Lake esekelwe kwi-Goldmont microarchitecture.
