I-Intel ivule i-firmware yomthombo yeyunithi ye-PSE (Programmable Services Engine), eqale ukuthunyelwa ngamaphrosesa omndeni wakwa-Elkhart Lake, njenge-Atom x6000E, elungiselelwe ukusetshenziswa kumadivayisi e-inthanethi Yezinto. Ikhodi ivuliwe ngaphansi kwelayisensi ye-Apache 2.0.
I-PSE iwumgogodla owengeziwe we-ARM Cortex-M7 osebenza kumodi yamandla aphansi. I-PSE ingasetshenziselwa ukwenza umsebenzi wesilawuli esishumekiwe, ukucubungula idatha kusuka kuzinzwa, ukuhlela isilawuli kude, ukwenza imisebenzi yenethiwekhi nokwenza imisebenzi ekhethekile ngokuhlukana.
Ekuqaleni, le kernel yayilawulwa kusetshenziswa i-firmware evaliwe, eyayivimbela ukuqaliswa kokusekelwa kwama-chips nge-PSE kumaphrojekthi avulekile afana ne-CoreBoot. Ikakhulukazi, ukunganeliseki kwakubangelwa ukuntuleka kolwazi mayelana nokulawulwa kwezinga eliphansi le-PSE nokukhathazeka ngokuvikeleka ngenxa yokungakwazi ukulawula izenzo ze-firmware. Ngasekupheleni konyaka odlule, iphrojekthi ye-CoreBoot yashicilela incwadi evulekile eya ku-Intel ibiza ukuthi i-firmware ye-PSE ivuleleke, futhi inkampani ekugcineni yalalela izidingo zomphakathi.
Inqolobane ye-firmware ye-PSE futhi iqukethe izivivinyo zokuqala zezinsiza zonjiniyela nezinhlelo zokusebenza eziyisibonelo ezingasebenza ohlangothini lwe-PSE, izingxenye zokusebenzisa i-RTOS Zephyr, i-firmware ye-ECLIte enokuqaliswa kokusebenza kwesilawuli esishumekiwe, kanye nokusetshenziswa kwereferensi ye-OOB (Ingaphandle- Band) isixhumi esibonakalayo sokulawula kanye nohlaka lokuthuthukiswa kohlelo lokusebenza.
