Ebizwa nge-ARM Mali-C71, ingumkhiqizo wokuqala odalwe ukuthengwa kwe-ARM kwe-Apical eseLoughborough ngonyaka owedlule.
Kuyi-hardware block elawulwa yi-software enikela nge-1.2Gpixel / s yokucubungula.
Izingxenyekazi zekhompuyutha ezinamakhamera afinyelela kwamane, ezikhiqiza imifudlana yesithombe esetshenzisiwe engasetshenziselwa ukushayela isibonisi - isibuko sokubuka ngemuva sombane ngokwesibonelo - noma ukusakazwa okuncane kungafakwa ekuhlakanipheni okufakelwayo kwemisebenzi efana nokuqashelwa kwento, ukunyakaza ukulinganisa nokuhlanganisa inzwa.
Ngokukhipha imininingwane yesithombe ngaphansi kwezimo zokugqama okuphezulu, ububanzi obuhlukahlukene obunamandla (ama-24 stop = 224 = 144dB) ukusebenza kokusebenza kuyenziwa.
Lokhu kudinga ukuvezwa okuningi (kusebenza nge-1, 2, 3 noma 4) kusuka kusenzwa sesithombe, ngakunye kusethingi yokuvezwa ehlukile. Ukunyakaza phakathi kokuvezwa ngenxa yejubane lemoto kubalwa lapho kucutshungulwa.
Ngemuva kokucutshungulwa kwezithombe eziningi, umphumela obanzi wobubanzi obunamandla ungacindezelwa ube yi-14, 12, 10 noma 8bits. Kuhlinzekwa iziteshi ezimbili zokucindezelwa ngasikhathi sinye, okhulumela i-ARM uRichard York utshele i-Electronics Weekly, eyodwa yombono womuntu ngesibonisi, kanye neyodwa yokubheka ama-algorithms wemishini.
Amakhamera anezinhlobo eziningi zama-pixel angafakwa. Lokhu kufaka phakathi: i-RGGB, i-RGB (IR), i-RCCC (lapho i-C = icacile) ne-RCCG.
Ngokusebenzisa ukusetshenziswa kwezimoto emqondweni, iprosesa lesithombe liyidizayini yokuphepha okusebenzayo - nge-ASIL D / ISO 26262 kanye nokuhambisana kwe-SIL3 / IEC 61508.
Kufakwe amasekethe angama-> 300 ukuthola amaphutha, ukuzihlola okuzakhelwe ngaphakathi, ukubhekelwa kabusha kwe-cyclic ezindleleni zedatha futhi yonke i-pixel imakwe ukuthembeka, kusho i-ARM.
Ukusekelwa kufaka phakathi isoftware eyinkomba yokulawula i-ISP, inzwa, ibhalansi emhlophe nokuzenzakalela, umgwaqo wesoftware yezimoto eyenzelwe ukuthobela i-ASIL, isethi yamathuluzi wokuhlela nokulinganisa, kanye nohlelo lwemvelo lokuxhasa ukulungiswa nokuletha ukusetshenziswa okuthile amacala nezinzwa.
Impahla enobuhlakani yeMali-C71 kulindeleke ukuthi ingene ~ 2mm2 kuma-SoCs, futhi "idlanzana elincane" lamakhasimende asevele aklanyelwe, kusho iYork, kubandakanya nelilodwa eline-silicon ebuya kwi-fab.
