Ezingu-16 zokuqala zilungiswa njengeziphazamiso zangaphakathi ze-microprocessor, kanti ezinye ziyiziphazamiso zangaphandle, okungukuthi inani eliphezulu lokuphazamiseka kwangaphandle linganwetshwa ku-240. Izici zayo eziyinhloko zimi kanje.

Iziphazamiso zangaphandle ezingama-240, isicelo sokuphazamiseka ngasinye sinezicucu ezizimele kanye nezingcezu zokulawula imaski, ezinamabhithi esimo azinikele.
Okubalulekile kokuphazamiseka okuhlelekayo kusekela amaleveli angu-2 wokuzalela
Ukuphazamisa okukhethekile okukhethekile kokungaphakathi/ngaphandle kwendlela, ukunqwabelanisa okuzenzakalelayo kwehadiwe, nokutholwa, ukujula okukhulu kwe-HPE kwamaleveli angu-2

I-Vector Table Free (i-VTF) indlela yokuphendula ephazamisayo, ukufinyelela okuqondile kweziteshi ezi-2 eziphazamisa amakheli e-vector
Qaphela: Ukujula okukhulu kwesidleke nokujula kwe-HPE okusekelwa izilawuli eziphazamisayo kuyahlukahluka kumamodeli e-microprocessor ahlukene, angatholakala kuThebula 1-1.
Ithebula le-vector leziphazamiso nezihlukile liboniswa kuThebula 3-1 ngezansi.

Ithebula 3-1 Okuhlukile kanye nokuphazamisa ithebula le-vector
