Ikhodi yomthombo yembobo ye-Doom yamafoni we-push-button ku-chip ye-Spreadtrum SC6531 ishicilelwe. Ukulungiswa kwe-chip ye-Spreadtrum SC6531 kuthatha cishe uhhafu wemakethe yezingcingo ezishibhile ze-push-button ezivela kumikhiqizo yaseRussia (okusele kungokwaMediaTek MT6261, amanye ama-chips awavamile).
Bebuyini ubunzima bokuthutha:
- Azikho izinhlelo zokusebenza zezinkampani zangaphandle ezitholakalayo kulawa mafoni.
- Inani elincane le-RAM - amamegabhayithi angu-4 kuphela (amabhrendi/abathengisi bavame ukuklelisa lokhu njengo-32MB - kodwa lokhu kuyadukisa, njengoba amamegabhithi, hhayi amamegabhayithi).
- Amadokhumenti avaliwe (ungathola kuphela ukuvuza kwenguqulo yokuqala nenesici), ngakho kuningi okutholwe kusetshenziswa ubunjiniyela obuhlanekezelwe.
I-chip isekelwe kuphrosesa ye-ARM926EJ-S ene-frequency engu-208 MHz (SC6531E) noma 312 MHz (SC6531DA), ingakwazi ukwehla iye ku-26 MHz, i-ARMv5TEJ processor architecture (akukho division kanye nephuzu elintantayo).
Kuze kube manje, ingxenye encane kuphela ye-chip isihloliwe: i-USB, isikrini nokhiye. Ngakho-ke, ungadlala kuphela ngefoni yakho exhunywe kukhompuyutha ngekhebula le-USB (izinsiza zomdlalo zidluliselwa kukhompyutha), futhi akukho msindo emdlalweni.
Njengamanje isebenzisa amafoni ayi-6 kweziyi-9 ahloliwe asuselwa ku-chip ye-SC6531. Ukuze ufake le chip kumodi yokuqalisa, udinga ukwazi ukuthi yimuphi ukhiye okufanele ubambe ngesikhathi sokuqalisa, okhiye bamamodeli ahloliwe: F+ F256: *, Digma LINX B241: isikhungo, F+ Ezzy 4: 1, Joy's S21: 0, Vertex M115: phezulu, i-Vertex C323: 0.
Amavidiyo amabili nawo ashicilelwe: ngomboniso imidlalo ocingweni nokuqhubeka 4 amanye amafoni.
I-PS: Into efanayo ishicilelwe ku-OpenNet, izindaba ezivela kimi, zihlelwe kuphela umqondisi wesayithi.
Ngaphandle kwelayisensi, kunzima ukusho ukuthi iyiphi ilayisensi okufanele ibe yikhodi etholwe yi-reverse engineering, ibheke njenge-copyleft - kopisha futhi ushintshe, ake abanye bayishintshe.
Igeyimu ye-Doom yasetshenziselwa ukuheha ukunaka, njengesibonelo, ngingathanda i-firmware yamahhala yamafoni afakiwe. Ama-chips awo anamandla kakhulu kunalawo asetshenziswa ku-firmware. Ngaphezu kwalokho, i-hardware ishibhile futhi isabalele, ngokungafani namafoni angavamile anama-OS "avulekile" noma lawo akuvumela ukuthi usebenzise ikhodi yakho. Kuze kube manje angikatholi muntu engingabambisana naye, futhi ubunjiniyela obuhlehlayo bunzima. Indawo enhle yokuqala kungaba ukuthola ukuphathwa kwekhadi le-SD kanye nokuphathwa kwamandla ukuze ukwazi ukusebenzisa lawa mafoni njengekhonsoli yokudlala. Ngokungeziwe ku-Doom, ungakwazi ukufaka i-emulator ye-NES/SNES.
