Imibuzo Evame Ukubuzwa

Iyini i-FPGA watchdog eqinisekiswe ngokusemthethweni futhi kungani ibalulekile ekusakazeni kwe-AM?

I-FPGA watchdog eqinisekiswe ngokusemthethweni isekethe yezingxenyekazi zekhompuyutha ukuziphatha kwayo okulungile okuye kwafakazelwa ngokwezibalo kusetshenziswa amathuluzi okuqinisekisa asemthethweni, esusa zonke izigaba zeziphazamisi ukuhlolwa kukodwa okungakwazi ukuzibamba. Okusakazweni kwe-AM emhubheni ongenamuntu, lokhu kubaluleke kakhulu - uma i-watchdog yehluleka, uhlelo lokusakaza lungavaleka kungekho muntu okhona ongangenela. Ukuqinisekisa okusemthethweni kuqinisekisa ukuthi inja izohlala isetha kabusha isistimu ngaphansi kwezimo zephutha ezishiwo, iyenze ifaneleke ukuthunyelwa okubalulekile kokuphepha, okungagadiwe.

Kungani kufanele usebenzise i-FPGA esikhundleni se-microcontroller kulolu hlobo lwe-watchdog?

Ama-FPGA anikezela ngokunqunywa, ukusebenza kwehadiwe okuhambisanayo ngaphandle kwesistimu yokusebenza ngaphezulu, okuwenza athembeke ngokwemvelo ezinhlelweni zokusebenza ze-watchdog. Ngokungafani nezilawuli ezincane, i-FPGA watchdog ayikwazi ukonakalisa iziphazamisi zesofthiwe, ukuchichima kwesitaki, noma izinqubo ezibalekayo - isebenza ezingeni elinengqondo. Esikhathini eside esingagadiwe sokusakazwa kwe-AM emhubheni lapho ukufinyelela kokulungisa kunzima, lokhu kwethembeka kwezinga lehadiwe kubalulekile. Ukuqinisekisa okusemthethweni komklamo kuqinisa futhi ukuzethemba kokuthi ingqondo ye-FPGA iziphatha ncamashi njengoba kucacisiwe ngaphansi kwazo zonke izimo zokufakwayo.

Le phrojekthi ingena kanjani ekusakazeni okubanzi noma ekulawuleni ingqalasizinda?

Le nja yokuqapha ye-FPGA isebenza njengowokuqala ukuthembeka kwezinga eliphansi elihlanganisa nezinhlelo zokuqapha nokuphatha ezisezingeni eliphezulu. Emaqenjini aphethe ingqalasizinda yokusakaza eceleni kwamanye amathuluzi okusebenza, izinkundla ezifana Mewayz — ezihlinzeka ngamamojula ahlanganisiwe angu-207 ngo-$19/ngenyanga — zihlinzeka ngohlobo lokugeleza komsebenzi okumaphakathi nendawo ezungezile nesendlalelo esizenzakalelayo lapho izexwayiso, ukugawulwa kwemithi, nokuxilongwa okukude okuvela kumasistimu ezingxenyekazi zekhompuyutha kungahlanganiswa futhi kusetshenzwe ngaphandle kokudinga ukuba khona kusayithi.

Ingabe ukuqinisekiswa okusemthethweni kuyasebenza kumaphrojekthi amancane wehadiwe, noma kungowezinhlangano ezinkulu kuphela?

Ukuqinisekisa okusemthethweni sekufinyeleleka kalula kubathuthukisi abangabodwana nasemaqenjini amancane, ngenxa yamathuluzi omthombo ovulekile njenge-SymbiYosys nezihloli zemodeli ezisebenza ngekhodi evamile ye-HDL. Le phrojekthi ikhombisa ukuthi ngisho nomzamo ogxile, we-hardware womthombo ovulekile ungasebenzisa izindlela ezisemthethweni zokukhiqiza imiklamo elungile. I-ecosystem ekhulayo yamathuluzi athengekayo ibonisa ithrendi yesofthiwe, lapho izinkundla ezifana Mewayz zenza amakhono ebhizinisi — amamojula angu-207, aqala ku-$19/ngenyanga — afinyeleleke kubakhi abazimele nasemaqenjini amancane ngokufanayo.
