Inkqubo ye-IC

I-general software programming ijolise kwizicelo ezikwiinkqubo zokusebenza zekhompyutha, isebenzisa iilwimi ezikumgangatho ophezulu, kwaye isebenza kwiiprosesa ezisetyenziswa ngokubanzi. I-IC programming isebenzisana ngokuthe ngqo nee-hardware chips, ifuna ukuqwalaselwa kweempawu zehardware ezifana neerejista kunye neeprotocol zonxibelelwano, idla ngokusebenzisa ulwimi lwe-assembly okanye iilwimi ezithile ze-chip, kwaye igcina iziphumo kwimemori ye-chip engaguqukiyo.

Iindidi eziqhelekileyo ziquka ii-microcontrollers (ii-MCU), ii-microprocessors (ii-MPU), ii-field-programmable gate arrays (ii-FPGA), ii-flash memory chips, kunye nee-digital signal processors (ii-DSP).

Inika ii-IC ingqiqo ethile yokuziphatha. Umzekelo, itshiphu yeBluetooth yenzelwe ukuseta iindlela zokusebenza kunye neeparamitha zonxibelelwano zoqhagamshelo lwesixhobo kunye nokudluliselwa kwedatha. Ngaphandle kokwenza iprogram, i-IC "yimveliso egqityiweyo kancinci" nje yehardware.

Kwii-IC ezisebenza ngokuphuma, jonga ukuba imiqondiso iyahambelana na nolindelo ngoqhagamshelo lwesekethe (umz., ukukhanya kwe-LED njengoko kucwangcisiwe). Kwii-IC zememori, funda idatha kunye ne-programmer okanye ujonge iiflegi zesimo setshiphu.

Ukufana: Zombini zisebenzisa i-interfaces zonxibelelwano ukudlulisela idatha kwimemori yetshiphusi.

Umahluko: Ii-MCU zibhala ikhowudi kwiFlash nge-JTAG/SWD interfaces; Ii-FPGA zilayisha idatha yoqwalaselo kwiitafile zokukhangela (ii-LUT) ukuze ziphinde zilungiselele i-hardware logic, idatha idla ngokugcinwa kwi-external flash kwaye ilayishwe nge-SPI.

Ibandakanya ukukhetha i-hardware/isoftware yeprogram, ukudibanisa i-hardware kwi-IC, ukuseta ii-chip parameters, ukulayisha iifayile zeprogram (.hex/.bin, njl.njl.), ukuqhuba i-programming, kunye nokwenza uvavanyo lokuqinisekisa kunye nokusebenza.

Igama elithi "Burn-in" ligama eliqhelekileyo lenkqubo ye-IC, elibhekisa ekubhaleni ikhowudi ngokusisigxina kwimemori ye-chip engaguqukiyo (umz., iFlash ye-MCU). Eli gama lavela kwimisebenzi yokuqala "yokutshisa" ene-high-voltage kwaye lisasetyenziswa nanamhlanje.

Imemori egcina idatha xa umbane ucinyiwe. Iindidi eziqhelekileyo kwi-IC programming ziquka iFlash (igcina ikhowudi/idatha) kunye ne-EEPROM (igcina ulwazi loqwalaselo), ngokungafaniyo nememori eguquguqukayo (umz., i-RAM).

Isoftware efakwe kwizixhobo zehardware, egcinwe kwimemori ye-IC engaguqukiyo, elawula imisebenzi esisiseko kwaye ibonelela ngeendawo zokunxibelelana zesoftware ephezulu, njenge-firmware ye-router elawula uqhagamshelo lwenethiwekhi.
