Ukusekelwa Komndeni Kwedivayisi ye-DSP IP Core
I-Intel inikezela ngamazinga alandelayo wosekelo lwedivayisi we-Intel FPGA IP cores:
- Usekelo oluthuthukisiwe—umongo we-IP uyatholakala ukuze ulingise futhi uhlanganiswe kulo mndeni wedivayisi. Uhlelo lwe-FPGA file (.pof) usekelo alutholakali kusofthiwe ye-Quartus Prime Pro Stratix 10 Edition Beta futhi ngenxa yalokho ukuvalwa kwesikhathi se-IP akunakuqinisekiswa. Amamodeli wesikhathi afaka phakathi izilinganiso zokuqala zobunjiniyela zokulibaziseka ngokusekelwe olwazini lwangemva kwesakhiwo. Amamodeli wesikhathi angase ashintshe njengoba ukuhlolwa kwe-silicon kuthuthukisa ukuhlobana phakathi kwe-silicon yangempela namamodeli wesikhathi. Ungasebenzisa lo mnyombo we-IP ekwakhiweni kwesistimu nezifundo zokusebenzisa insiza, ukulingisa, ukuphina, ukuhlola ukubambezeleka kwesistimu, ukuhlola isikhathi okuyisisekelo (ibhajethi yamapayipi), nesu lokudlulisa le-I/O (ububanzi bendlela yedatha, ukujula kokuqhuma, ukuhwebelana kwezindinganiso ze-I/O ).
- Usekelo lokuqala—I-Intel iqinisekisa i-IP core ngamamodeli wesikhathi sokuqala walo mndeni wedivayisi. I-IP core ihlangabezana nazo zonke izidingo zokusebenza, kodwa kungenzeka ukuthi isacutshungulwa isikhathi somndeni wedivayisi. Ungayisebenzisa kumiklamo yokukhiqiza ngokucophelela.
- Usekelo lokugcina—I-Intelverifyes i-IP core ngamamodeli okugcina wesikhathi walo mndeni wedivayisi. I-IP core ihlangabezana nazo zonke izimfuneko zokusebenza nezesikhathi zomndeni wedivayisi. Ungayisebenzisa kumiklamo yokukhiqiza.
Inkampani ye-Intel Wonke Amalungelo Agodliwe. I-Intel, ilogo ye-Intel, nezinye izimpawu ze-Intel yizimpawu zokuthengisa ze-Intel Corporation noma izinkampani ezingaphansi kwayo. I-Intel iqinisekisa ukusebenza kwe-FPGA yayo kanye nemikhiqizo yesemiconductor ekucacisweni kwamanje ngokuvumelana newaranti evamile ye-Intel, kodwa igodla ilungelo lokwenza izinguquko kunoma imiphi imikhiqizo namasevisi nganoma yisiphi isikhathi ngaphandle kwesaziso. I-Intel ayithathi mthwalo noma isikweletu esivele ngenxa yesicelo noma ukusetshenziswa kwanoma yiluphi ulwazi, umkhiqizo, noma isevisi echazwe lapha ngaphandle kwalapho okuvunyelwene ngakho ngokubhaliwe yi-Intel. Amakhasimende e-Intel ayelulekwa ukuthi athole inguqulo yakamuva yokucaciswa kwedivayisi ngaphambi kokuthembela kunoma yiluphi ulwazi olushicilelwe nangaphambi kokufaka ama-oda emikhiqizo noma amasevisi. *Amanye amagama namabhrendi angafunwa njengempahla yabanye.

Umsebenzi we-SinCos
Ibala i-sine ne-cosine ye-engeli a.
Umsebenzi we-SinCos
ALTERA_CORDIC IP Core User Guide 683808 | 2017.05.08
Umsebenzi usekela ukulungiselelwa okubili, kuye ngesibaluli sophawu lwe-a:
- Uma u-a esayiniwe, ububanzi bokufaka obuvunyelwe buthi [-π+π] futhi ububanzi bokuphumayo be-sine ne-cosine bungu-∈[−1,1].
- Uma u-a engasayiniwe, i-IP core ikhawulela okokufaka ku-[0+π/2] futhi ikhawulela ububanzi bokuphumayo ku-[0,1].
Umsebenzi we-Atan2
Ibala umsebenzi u-atan2(y, x) kusuka kokokufaka y kanye no-x.
Umsebenzi we-Atan2
- Uma u-x kanye no-y esayiniwe, i-IP core inquma ububanzi bokufakwayo obusuka kumafomethi wamaphoyinti angashintshi.
- Ububanzi bokuphumayo bungu-[-π+π].
Vector Translate Umsebenzi
Umsebenzi wokuhumusha ivekhtha uyisandiso somsebenzi we-atan2. Ikhipha ubukhulu bevekhtha yokufaka kanye ne-engeli a=atan2(y,x).
Vector Translate Umsebenzi
Umsebenzi uthatha okokufaka u-x kanye no-y kanye nokuphumayo a=atan2(y, x) kanye ne-M = K(x2+y2)0.5. U-M ubukhulu be-vector yokufaka i-v=(x,y)T, ekalwa ngokuguquguquka okuthile kwe-CORDIC eguqulela ku-1.646760258121, engaphezu kwemvelo, ngakho ayinalo inani elinqunyiwe. Imisebenzi isekela ukucupha okubili, kuye ngesibaluli sophawu sika-x kanye no-y:
- Uma okokufaka kusayiniwe, amafomethi anikeza ububanzi bokufaka obuvunyelwe. Kulokhu kumisa ububanzi bokuphumayo buka-a is∈[−π+π]. Ibanga lokuphumayo lika-M lincike ebangeni lokokufaka lika-x kanye no-y, ngokuya ngefomula yobukhulu.
- Uma okokufaka kungasayiniwe, i-IP core ikhawulela inani lokukhiphayo lika-[0+π/2]. Inani lobukhulu lisancike kufomula.
Vector Rotate Umsebenzi
Umsebenzi wokuzungezisa ivekhtha uthatha i-vector v= (x,y)T enikezwe izixhumanisi ezimbili x kanye no-y kanye ne-engeli a. Umsebenzi ukhiqiza ukuzungezisa okufanayo kwevekhtha v nge-engeli a ukukhiqiza i-vector v0=(x0,y0)T.
Vector Rotate Umsebenzi
Ukuzungezisa ukuzungezisa okufanayo ngenxa yokuthi ubukhulu bevekhtha v0 ekhiqiziwe bukhushulwa yi-CORDIC ethize engaguquki engu-K(˜1.646760258121). Izibalo zezixhumanisi ze-vector v0 yilezi:
- x0 = K(xcos(a)−ysin(a))
- y0 = K(xsin(a)+ ycos(a))
Uma usetha isibaluli sophawu sibe iqiniso kokokufaka kuka-x,y komsebenzi, i-IP core ikhawulela ububanzi bawo kokuthi [-1,1]. Unikeza inombolo yamabhithi ayingxenye. I-engeli yokufaka a ivunyelwe kububanzi [−π+π], futhi inenani elifanayo lamabhithi amaqhezu njengokunye okokufaka. Unikeza amabhithi amafractional okukhiphayo futhi ububanzi obuphelele bokuphumayo ngu-w=wF+3, esayiniwe. Okokufaka okungasayiniwe okungu-x,y, ingqikithi ye-IP ikhawulela ububanzi ku-[0,1], i-engeli a ukuya ku-[0,π].
