I-MICROCHIP CoreFPU Iyunithi Yephoyinti Elintantayo Eliyinhloko

I-MICROCHIP-CoreFPU-Cor-Floating-Point-Unit-produxt

 

Isingeniso 

  • I-Core Floating Point Unit (CoreFPU) yakhelwe ukusebenza kwe-arithmetic yephuzu elintantayo kanye nokuguqula, ukuze uthole izinombolo zephoyinti elintantayo elinembayo elilodwa neliphindwe kabili. I-CoreFPU isekela iphoyinti elingaguquki ukuya endaweni elintantayo kanye nephoyinti elintantayo ukuya ekuguquleni kwamaphoyinti angashintshi kanye nemisebenzi yephoyinti elintantayo, yokukhipha, kanye nemisebenzi yokuphindaphinda. Izinga le-IEEE® le-Floating-Point Arithmetic (IEEE 754) liyindinganiso yobuchwepheshe yokubala iphuzu elintantayo.
  • Okubalulekile: I-CoreFPU isekela izibalo ngezinombolo ezijwayelekile kuphela, futhi kusekelwa ulimi lwe-Verilog kuphela; I-VHDL ayisekelwe.

Isifinyezo
Ithebula elilandelayo linikeza isifinyezo sezimpawu ze-CoreFPU.

Ithebula 1. Izici ze-CoreFPU

Incazelo Esebenzayo

  • Izinga le-IEEE le-Floating-Point Arithmetic (IEEE 754) liyindinganiso yobuchwepheshe yokubala iphuzu elintantayo. Igama elithi floating-point libhekisela endaweni eyi-radix yenombolo (iphoyinti ledesimali noma indawo kanambambili), ebekwa noma yikuphi ngokuphathelene nezinombolo ezibalulekile zenombolo.
    Inombolo yephoyinti elintantayo ivamise ukuvezwa kumbhalo wesayensi, ngengxenye ethi (F), kanye ne-eksponenti (E) yerediksi ethile (r), ngendlela ethi F × r^E. Izinombolo zedesimali zisebenzisa i-radix engu-10 (F × 10^E); kuyilapho izinombolo kanambambili zisebenzisa i-radix ka-2 (F × 2^E).
  • Ukumelwa kwenombolo yephoyinti elintantayo akuhlukile. Okwesiboneloample, inombolo engu-55.66 imelwe njenge-5.566 × 10^1, 0.5566 × 10^2, 0.05566 × 10^3, njalonjalo. Ingxenye eyingxenye ijwayelekile. Efomini elejwayelekile, kunedijithi eyodwa kuphela engeyona uziro ngaphambi kwephoyinti le-radix. Okwesiboneloample, inombolo yedesimali 123.4567 ijwayelekile njenge-1.234567 × 10^2; inombolo kanambambili 1010.1011B ijwayeleke njenge-1.0101011B × 2^3.
  • Kubalulekile ukuqaphela ukuthi izinombolo zamaphuzu antantayo zinenkinga yokulahlekelwa ukunemba lapho zimelelwa nenani elimisiwe lamabhithi (okwangaphambili)ample, 32-bit noma 64-bit). Lokhu kungenxa yokuthi kunenombolo engapheli yezinombolo zangempela (ngisho nangaphakathi kwebanga elincane ukusuka ku-0.0 kuye ku-0.1). Ngakolunye uhlangothi, i
    I-n-bit iphethini kanambambili imelela izinombolo ezicacile ezingu-2^n. Ngakho-ke, akuzona zonke izinombolo zangempela ezimelwe. Ukulinganisa okuseduze kusetshenziswa esikhundleni salokho, okuholela ekulahlekeni kokunemba.

Inombolo yephoyinti elintantayo elinembayo imelwe kanje:

  • Ibhithi yesignali: 1-bit
  • Ububanzi be-eksponenti: amabhithi angu-8
  • Ukunemba okubalulekile: amabhithi angama-24 (amabhithi angama-23 agcinwe ngokusobala)

Umfanekiso 2-1. 32-bit Uzimele

Iyunithi yephoyinti-e-MICROCHIP-CoreFPU-Cor-Floating-(2)Inombolo yephoyinti elintantayo enembayo imelwe kanje:

  • Ibhithi yesignali: 1-bit
  • Ububanzi be-eksponenti: amabhithi angu-11
  • Ukunemba okubalulekile: amabhithi angama-53 (amabhithi angama-52 agcinwe ngokusobala)

Umfanekiso 2-2. 64-bit Uzimele Iyunithi yephoyinti-e-MICROCHIP-CoreFPU-Cor-Floating-(3)I-CoreFPU iwukuhlanganiswa kwezinga eliphezulu kwamamojula amabili okuguqula (I-Fixed to Float point and Float to Fixed point) kanye nemisebenzi emithathu ye-arithmetic (FP ADD, FP SUB, ne-FP MULT). Umsebenzisi angamisa noma yikuphi okunye kokusebenza ngokususelwe kwimfuneko ukuze izinsiza zisetshenziselwe umsebenzi okhethiwe.

Iphuzu Eligxilile libe Iphuzu Elintantayo (Ukuguqulwa)

I-CoreFPU emiswe njengegxilile endaweni entantayo idlulisela indawo engashintshi kumojula yokuguqula yephoyinti elintantayo. Okokufaka (i-ain) ku-CoreFPU inoma iyiphi inombolo yephoyinti elingashintshi equkethe inombolo ephelele kanye namabhithi ayingxenye. I-CoreFPU configurator inezinketho zokukhetha inombolo yokufaka nobubanzi bengxenye. Okokufaka kuvumelekile kusiginali ye-di_valid futhi okukhiphayo kuvumeleke kokuthi do_valid. Okukhiphayo (i-aout) yokusebenza okugxilile ukuze kuntante kufomethi yephoyinti elintantayo elinembayo elilodwa noma eliphindwe kabili.
ExampI-le yokusebenza kwephoyinti eligxilile ukuya endaweni elintantayo ifakwe ohlwini kuthebula elilandelayo.

Ukusekelwa kwe-Microchip FPGA

Iqembu lemikhiqizo ye-Microchip FPGA lisekela imikhiqizo yalo ngezinkonzo ezehlukene zokusekela, okuhlanganisa Isevisi Yamakhasimende, Isikhungo Sokusekela Ubuchwepheshe Bekhasimende, a webindawo, kanye namahhovisi okuthengisa emhlabeni wonke. Amakhasimende aphakanyiswa ukuthi avakashele izinsiza ze-inthanethi ze-Microchip ngaphambi kokuxhumana nosekelo njengoba kungenzeka ukuthi imibuzo yawo isiphenduliwe.
Xhumana Nesikhungo Sosizo Lobuchwepheshe ngokusebenzisa i webindawo ku www.microchip.com/support. Yisho inombolo Yengxenye Yedivayisi ye-FPGA, khetha isigaba samacala afanelekile, bese ulayisha idizayini files ngenkathi udala ikesi lokusekela lobuchwepheshe.
Xhumana Nesevisi Yekhasimende ukuze uthole ukwesekwa kwemikhiqizo okungeyona eyobuchwepheshe, njengentengo yomkhiqizo, ukuthuthukiswa komkhiqizo, ulwazi lokubuyekeza, isimo soku-oda, nokugunyazwa.

Isaziso Somthetho
Lokhu kushicilelwa kanye nolwazi olulapha kungasetshenziswa kuphela emikhiqizweni ye-Microchip, okuhlanganisa ukuklama, ukuhlola, nokuhlanganisa imikhiqizo ye-Microchip nohlelo lwakho lokusebenza. Ukusetshenziswa kwalolu lwazi nganoma iyiphi enye indlela kwephula le migomo. Ulwazi olumayelana nezinhlelo zokusebenza zedivayisi lunikezwa ukuze kube lula kuwe futhi lungase luthathelwe indawo yizibuyekezo. Kuyisibopho sakho ukuqinisekisa ukuthi isicelo sakho sihlangabezana nezicaciso zakho. Xhumana nehhovisi lakho lendawo yokuthengisa le-Microchip ukuze uthole ukwesekwa okwengeziwe noma, thola ukwesekwa okwengeziwe kokuthi www.microchip.com/en-us/support/design-help/client-support-services

Ukusetshenziswa kwamadivayisi e-Microchip ekusekeleni impilo kanye/noma izicelo zokuphepha kusengozini yomthengi ngokuphelele, futhi umthengi uyavuma ukuvikela, ukunxephezela nokubamba i-Microchip engenabungozi kunoma yimuphi nanoma yimuphi umonakalo, izimangalo, amasudi, noma izindleko ezibangelwa ukusetshenziswa okunjalo. Awekho amalayisensi adluliswayo, ngokusobala noma ngenye indlela, ngaphansi kwanoma imaphi amalungelo empahla yengqondo ye-Microchip ngaphandle kwalapho kushiwo ngenye indlela.

Isici Sokuvikela Ikhodi Yamadivayisi e-Microchip
Qaphela imininingwane elandelayo yesici sokuvikela ikhodi emikhiqizweni ye-Microchip:

  • Imikhiqizo ye-Microchip ihlangabezana nokucaciswa okuqukethwe ku-Microchip Data Sheet yayo.
  • I-Microchip ikholelwa ukuthi umkhaya wayo wemikhiqizo uvikelekile uma usetshenziswa ngendlela ehlosiwe, ngaphakathi kwezicaciso zokusebenza, nangaphansi kwezimo ezivamile.
  • Amanani e-Microchip futhi avikela ngokunamandla amalungelo ayo okuvikela ubunikazi bokusungula. Imizamo yokwephula izici zokuvikela ikhodi yemikhiqizo ye-Microchip inqatshelwe ngokuphelele futhi ingase yephule uMthetho we-Digital Millennium Copyright Act.
  • I-Microchip nanoma yimuphi omunye umkhiqizi we-semiconductor ongaqinisekisa ukuphepha kwekhodi yayo. Ukuvikelwa kwekhodi akusho ukuthi siqinisekisa ukuthi umkhiqizo “awunakunqamuka”. Ukuvikelwa kwekhodi kuhlala kuvela njalo. I-Microchip izinikele ekuthuthukiseni ngokuqhubekayo izici zokuvikela ikhodi zemikhiqizo yethu.
