Amabhodi Angcono Kakhulu we-NXP MCU - Izinketho Eziphezulu Eziyi-10
Imininingwane
Ibhodi le-NXP MCU.I-NXP Arm® Cortex®-M4 Based Microcontrollers – LPC Family
Isilawuli esincane se-LPC esisekelwe kumongo we-Arm® Cortex®-M4 singasebenza ngefrikhwensi yewashi efinyelela ku-204MHz, sifinyelele izinga eliphezulu lokuhlanganiswa kwesistimu nokusebenza kahle kwamandla okuhle kakhulu.
Ngenkathi kusiza amakhasimende ukunciphisa izindleko zokuklama nokuba yinkimbinkimbi.Eminye yale mikhiqizo ifaka iphrosesa ye-Cortex®-M4 eneyunithi yendawo entantayo eyakhelwe ngaphakathi.Iphothifoliyo ye-LPC iqukethe okusekelwe ku-3.
Umndeni wama-Cortex®-M4 cores ane-single-core kanye ne-multi-core architecture esekela ukwahlukanisa okusebenzayo kwemojuli yohlelo lokusebenza nokusebenza kwamandla okulungiswayo.
I-LPC4000 Series: I-High Speed Multiple Connections Amapheripheli athuthukileNgokusekelwe kumongo we-Cortex®-M4/M4F, uchungechunge lwe-LPC4000 lungasekelaIzindawo zokusebenzelana eziningi zamapheripheral afana ne-Ethernet, i-USB (umsingathi noma idivayisi), i-CAN, nesibonisi se-LCD.
Ukusakazwa kwedatha yomkhawulokudonsa ophezulu okuvumelanisa.I-LPC4000 ene-LPC177x/8x kanyeI-ARM7LPC2x00 umndeni wemikhiqizo iphinikhodi iyahambisana ne-SPI flash interface(I-SPIFI), engaxhuma kalula ngememori ye-QSPI flash yezindleko eziphansi ngesivinini esikhulu.I-SPIFI ukuya phezuluIndlela engabizi kakhulu yokwengeza amamegabhayithi ohlelo noma inkumbulo ye-flash yedatha kusistimu yakhoohlelweni.Iphrosesa ye-LPC4000 yokulawula isignali yedijithali (DSC) yobunjiniyela bokuklamaukuhlukaniswa kuletha amandla aphezulu okucubungula isignali.Lawa masethi esistimu ye-DSC processorukuminyana okuphezulu, okunciphisa izindleko nobunkimbinkimbi bomklamo wesistimu ngenkathi usebenzisa ii-toolchain eyodwa yokwenza umjikelezo wokuklama ube lula.Uchungechunge lwe-LPC4000 luhlanganisa i-microIzinzuzo zesilawuli kanye ne-MAC yomjikelezo owodwa, ubuchwepheshe bedatha yokufundisa eyodwa (i-SIMD).Ukusebenza okuphezulu kwemisebenzi yesignali yedijithali efana ne-arithmetic, i-saturation arithmetic kanye neyunithi yephoyinti elintantayo (FPU)uyakwazi.
Izinhlelo zokusebenza
➢ Izinhlelo zokusebenza ezidinga i-SDRAM enwetshiwe yangaphandle noma ukulungiselelwa okuhlukile kwememori ye-flash
➢ Imikhiqizo eshumekiwe edinga ukuboniswa kwe-LCD kombala
➢ Izikhathi ezidinga isilawuli sesignali yedijithali
Uchungechunge lwe-LPC4300: i-multi-core, ukusebenza okuphezulu, ukuxhumana okuningi
Uchungechunge lwe-LPC4300 luhlanganisa i-asymmetric dual-core architecture (Arm® Cortex®-M4F kanye ne-Cortex®-
M0) ukusebenza okuphezulu nokuguquguquka, kanye nezinketho ezihlukahlukene zokuxhuma ngesivinini esikhulu, izibali sikhathi ezithuthukisiwe, i-analog;
Izici zokuphepha ozikhethela ukuze uvikele ikhodi nokuxhumana kwedatha.Imisebenzi ye-DSP inika amandla konke
Uchungechunge lwe-LPC4300 lungasekela izinhlelo zokusebenza ezisuselwe kuma-algorithms ayinkimbinkimbi.Izinketho ze-Flash nezingenayo i-flash
Isekela ukucushwa kwememori enkulu yangaphakathi nangaphandle eguquguqukayo.Izikhonkwane zayo nesoftware ziyefana nezo zochungechunge lwe-LPC1800
Ihambisana nochungechunge lwemikhiqizo, enikeza lula ukuthuthukiswa okungenamthungo ukuze kuthuthukiswe ukusebenza kokucubungula, ngenkathi ikhulisa
Ukuvumelana nezimo ukwaba imisebenzi yohlelo lokusebenza ngokunengqondo phakathi kwama-cores ahlukene.
Isakhiwo se-LPC4300 sisebenzisa ama-cores amabili, inkimbinkimbi
Iphrosesa ye-Cortex®-M4F, kanye ne-Cortex®-M0 coprocessor core.i-multicore
isitayela, singabona kalula ukwakheka okuhlukene ukuze kwandiswe ukusebenza kahle, ukuze i-Cortex®- enamandla
I-M4F core iphatha ama-algorithms, ivumela i-coprocessor ye-Cortex®-M0 ilawule ukunyakaza kwedatha kanye nokucubungula kwe-I/O.
Imodi ye-Multi-core iphinde yehlise isikhathi sokuya emakethe ngoba ukuklama nokususa iphutha kusendaweni eyodwa yokuthuthukiswa
Kuqediwe.Lawa ma-processor cores asekelwa ama-peripheral amaningi asebenza kahle kakhulu, ukulawulwa kokuphazamiseka okudidiyelwe
Imisebenzi yokulawula kanye nezindlela zamandla aphansi zingaletha izindlela ezintsha zonjiniyela abashumekiwe ukuze baxazulule ngempumelelo izinkinga eziyinkimbinkimbi.
izinkinga zedizayini eziyinkimbinkimbi.Ngokwezidingo ezahlukahlukene, ungakhetha kalula ukuthi udinga inkumbulo ye-on-chip flash.
