Uhlelo lwe-IC

Uhlelo lwesofthiwe olujwayelekile luhlose izinhlelo zokusebenza ezinhlelweni zokusebenza zekhompyutha, lusebenzisa izilimi ezisezingeni eliphezulu, futhi lusebenza kumaprosesa ajwayelekile. Uhlelo lwe-IC luxhumana ngqo nama-hardware chip, ludinga ukucatshangelwa kwezici zehadiwe njengerejista kanye nezinqubo zokuxhumana, luvame ukusebenzisa ulimi lokuhlanganisa noma izilimi ezithile ze-chip, futhi lugcina imiphumela kwimemori ye-chip engaguquki.

Izinhlobo ezivamile zifaka phakathi ama-microcontroller (ama-MCU), ama-microprocessor (ama-MPU), ama-field-programmable gate arrays (ama-FPGA), ama-flash memory chip, kanye nama-digital signal processors (ama-DSP).

Inika ama-IC i-logic ethile yokuziphatha. Isibonelo, i-chip ye-Bluetooth ihlelwe ukusetha izindlela zokusebenza kanye nemingcele yokuxhumana yokuxhumeka kwedivayisi kanye nokudluliswa kwedatha. Ngaphandle kohlelo, i-IC imane nje "ingumkhiqizo oqediwe kancane".

Kuma-IC anikwe amandla okukhipha, bheka ukuthi amasignali ahambisana yini nokulindelekile ngokuxhumeka kwesekethe (isb., ukukhanya kwe-LED njengoba kuhleliwe). Kuma-IC enkumbulo, funda idatha nomhleli noma uhlole amafulegi esimo se-chip.

Ukufana: Zombili zisebenzisa izixhumi zokuxhumana ukuze zidlulisele idatha kwimemori ye-chip.

Umehluko: Ama-MCU abhala ikhodi ku-Flash ngokusebenzisa izixhumi ze-JTAG/SWD; Ama-FPGA alayisha idatha yokucushwa kumathebula okubheka (ama-LUT) ukuze ahlele kabusha i-hardware logic, idatha ivame ukugcinwa ku-flash yangaphandle futhi ilayishwe nge-SPI.

Kuhlanganisa ukukhetha ihadiwe/isofthiwe yokuhlela, ukuxhuma ihadiwe ku-IC, ukusetha amapharamitha e-chip, ukulayisha amafayela okuhlela (.hex/.bin, njll.), ukwenza ukuhlela, kanye nokwenza ukuhlolwa kokuqinisekisa nokusebenza.

Igama elithi "Burn-in" liyigama elivamile lohlelo lwe-IC, elibhekisela ekubhaleni ikhodi unomphela kwimemori ye-chip engashintshi (isb., i-MCU's Flash). Leli gama laqala ekusebenzeni "kokushisa" kwamandla aphezulu futhi lisasetshenziswa nanamuhla.

Imemori egcina idatha uma ugesi ucishiwe. Izinhlobo ezivamile kuhlelo lwe-IC zifaka phakathi i-Flash (igcina ikhodi/idatha) kanye ne-EEPROM (igcina ulwazi lokucushwa), ngokungafani nememori eguquguqukayo (isib. i-RAM).

Isofthiwe efakwe kumadivayisi ehadiwe, egcinwe kwimemori ye-IC engaguquki, elawula imisebenzi eyisisekelo futhi ehlinzeka ngezixhumi zesofthiwe esezingeni eliphezulu, njenge-firmware ye-router elawula ukuxhumana kwenethiwekhi.

Umehluko usezinhlakeni zokuhlela (isib. i-ST's JTAG/SWD vs. i-Microchip's ICD), amathuluzi (isib. i-ST-Link vs. i-MPLAB X), ukucushwa kwerejista, kanye nokusekelwa kolimi lokuhlela.

Kudinga ukunikezwa kwamandla okuzinzile, izindlela zokulwa nokungaguquguquki (isb., amabhande esihlakala/amabhentshi okusebenza), ihadiwe yokuhlela ehambisanayo (izixhumi ezithembekile), kanye nemithombo ethile yewashi yama-chip asheshayo.

Ihlinzeka ngezindawo zokuthuthukiswa ezihlanganisiwe (ama-IDE), isofthiwe evuthayo, kanye nezishayeli, yenza kube lula ukuhlela ngezinhlaka zomtapo wolwazi/zokuthuthukiswa ukuqinisekisa ukuhlanganiswa kwekhodi, ukulungisa amaphutha, kanye nokudluliswa kwedatha.

Inani elibalwe kusukela kudatha yefayela lokuhlela ukuqinisekisa ukuhambisana kwedatha ngaphambi nangemva kokushiswa. Ukufana kubonisa ukuhlela okulungile; ukungafani kungabonisa amaphutha okudlulisa noma amaphutha e-chip.

Uhlelo lokuqapha izinga lokushisa oluhlakaniphile: I-MCU iqoqa idatha evela kuzinzwa zokushisa, ilawula abalandeli/ama-heater ngokusekelwe emikhawulweni, ngokuhlela okuvumela ukucutshungulwa kwedatha, ukulawula okunengqondo, kanye nokuxhumana.

Umklamo wesekethe unikeza isisekelo sehadiwe (ukunikezwa kwamandla/izixhumi/izixhumi) zokuhlela, kuyilapho izinhlelo zilawula ama-IC ukuze kufezwe imisebenzi yesekethe. Ukukhethwa kwesixhumi kuthinta ikhodi yokuhlela, futhi izidingo zokuhlela zingase zithuthukise umzila wesekethe.
