Inkcazo esebenzayo
- UmGangatho we-IEEE we-Arithmetic yeNqaku eliNtandayo (IEEE 754) ngumgangatho wobugcisa wokubalwa kwamanqaku adadayo. Igama elithi indawo edadayo libhekiselele kwindawo yeradix yenani (indawo yedesimali okanye indawo yokubini), ebekwe naphi na ngokubhekiselele kumanani abalulekileyo yenani.
Inani lendawo edadayo lidla ngokuchazwa kubhalo lwenzululwazi, kunye neqhezu (F), kunye ne-exponent (E) yeradix ethile (r), ngokohlobo lwe-F × r^E. Amanani eedesimali asebenzisa i-radix ye-10 (F × 10^E); ngelixa amanani okubini esebenzisa i-radix ye-2 (F × 2^E). - Ukumelwa kwenani lendawo edadayo akuyodwa. Umzekeloample, inani le-55.66 limelwe njenge-5.566 × 10 ^ 1, 0.5566 × 10^2, 0.05566 × 10^3, njalo njalo. Inxalenye yeqhezu iqhelekile. Kwifom yesiqhelo, kukho idijithi enye kuphela engeyiyo i-zero phambi kwendawo ye-radix. Umzekeloample, inani lokugqibela 123.4567 liqhelekile njenge 1.234567 × 10^2; inombolo yokubini 1010.1011B iqhelekile njenge 1.0101011B × 2^3.
- Kubalulekile ukuqaphela ukuba amanani amanqaku adadayo anengxaki yokulahleka kokuchaneka xa emelwe ngenani elimiselweyo lamasuntswana (kwi-ex.ample, 32-bit okanye 64-bit). Oku kungenxa yokuba kukho inani elingenasiphelo lamanani okwenene (kwanaphakathi koluhlu oluncinci ukusuka ku-0.0 ukuya ku-0.1). Kwelinye icala, i
i-n-bit ipateni yokubini imele i-finite 2^n amanani ahlukileyo. Ngenxa yoko, asingawo onke amanani okwenene amelweyo. Uqikelelo olusondeleyo lusetyenziswa endaweni yoko, okukhokelela ekulahlekeni kokuchaneka.
Inombolo enye yendawo edadayo echanekileyo imelwe ngolu hlobo lulandelayo:
- Intwana yomqondiso: 1-bit
- Exponent ububanzi: 8 bits
- Ukuchaneka okubalulekileyo: ii-bits ezingama-24 (ii-23 bits zigcinwe ngokucacileyo)
Umfanekiso 2-1. 32 bit isakhelo
Inombolo yendawo edadayo echaneke kabini imelwe ngolu hlobo lulandelayo:
- Intwana yomqondiso: 1-bit
- Exponent ububanzi: 11 bits
- Ukuchaneka okubalulekileyo: ii-bits ezingama-53 (ii-52 bits zigcinwe ngokucacileyo)
Umfanekiso 2-2. 64 bit isakhelo 
I-CoreFPU yinqanaba eliphezulu lokudityaniswa kweemodyuli ezimbini zokuguqula (i-Fixed to Float point and Float to Fixed point) kunye nemisebenzi emithathu ye-arithmetic (FP ADD, FP SUB, kunye ne-FP MULT). Umsebenzisi unokuqwalasela nayiphi na imisebenzi esekelwe kwimfuno ukuze izibonelelo zisetyenziselwe umsebenzi okhethiweyo.
Lo mfanekiso ulandelayo ubonisa umgangatho ophezulu we-CoreFPU block diagram enezibuko.

Imbali yohlaziyo
Imbali yohlaziyo ichaza utshintsho oluthe lwaphunyezwa kuxwebhu. Ezi nguqulelo zidweliswe ngohlaziyo, kuqalwa kolona papasho lwangoku.
Microchip FPGA Inkxaso
Iqela leemveliso zeMicrochip FPGA libuyisela iimveliso zalo ngeenkonzo ezahlukeneyo zenkxaso, kubandakanya iNkonzo yabaThengi, iZiko leNkxaso yobuGcisa yabaThengi, a webindawo, kunye neeofisi zokuthengisa zehlabathi. Abathengi bayacetyiswa ukuba bandwendwele iMicrochip imithombo ye-intanethi ngaphambi kokuqhagamshelana nenkxaso njengoko kunokwenzeka ukuba imibuzo yabo sele iphendulwe.
Qhagamshelana neZiko leNkxaso yobuGcisa nge webindawo kwi www.microchip.com/support. Khankanya inombolo yeCandelo leSixhobo seFPGA, khetha udidi lwetyala elifanelekileyo, kwaye uyilo lokulayisha files ngelixa usenza imeko yenkxaso yobugcisa.
Qhagamshelana neNkonzo yabaThengi ngenkxaso yemveliso engeyiyo eyobugcisa, njengamaxabiso emveliso, ukuphuculwa kwemveliso, ulwazi lokuhlaziya, isimo somyalelo kunye nokugunyaziswa.

Ukusetyenziswa kwezixhobo zeMicrochip kwinkxaso yobomi kunye / okanye izicelo zokhuseleko ngokupheleleyo kumngcipheko womthengi, kwaye umthengi uyavuma ukukhusela, ukuhlawulela kwaye ubambe iMicrochip engenabungozi kuyo nayiphi na kunye nawo wonke umonakalo, amabango, iisuti, okanye iindleko ezibangelwa kukusetyenziswa okunjalo. Akukho zilayisenisi zigqithiswayo, ngokungafihlisiyo okanye ngenye indlela, phantsi kwawo nawaphi na amalungelo epropathi yemveliso yeMicrochip ngaphandle kokuba kuchazwe ngenye indlela.
Microchip Devices Code Protection Feature
Qaphela ezi nkcukacha zilandelayo zenqaku lokhuseleko lwekhowudi kwiimveliso zeMicrochip:
- Iimveliso zeMicrochip ziyahlangabezana nemigaqo equlethwe kwiMicrochip Data Sheet yazo.
- IMicrochip ikholelwa ukuba usapho lwayo lweemveliso lukhuselekile xa lusetyenziswa ngendlela ecetywayo, ngokwemigaqo yokusebenza, naphantsi kweemeko eziqhelekileyo.
- Ixabiso leMicrochip kwaye likhusela ngokungqongqo amalungelo epropathi enomgangatho ophezulu wokuqonda. Iinzame zokwaphula ikhowudi yokukhusela iimpawu zeemveliso zeMicrochip zithintelwe ngokungqongqo kwaye zinokwaphula umthetho weDigital Millennium Copyright Act.
- Ayikho i-Microchip okanye nawuphi na umenzi we-semiconductor onokuqinisekisa ukhuseleko lwekhowudi yayo. Ukukhuselwa kwekhowudi akuthethi ukuba siqinisekisa ukuba imveliso "ayinakwaphulwa". Ukhuseleko lwekhowudi luhlala luvela. I-Microchip izinikele ekuphuculeni ngokuqhubekayo iimpawu zokukhusela ikhowudi kwiimveliso zethu.
