Thandizo la Banja la DSP IP Core
Intel imapereka magawo otsatirawa othandizira zida za Intel FPGA IP cores:
- Thandizo lotsogola - IP core ilipo kuti iyerekeze ndi kuphatikizira banja la chipangizochi. Pulogalamu ya FPGA file (.pof) chithandizo sichikupezeka pa pulogalamu ya Beta ya Quartus Prime Pro Stratix 10 Edition ndipo motero kutseka kwa nthawi ya IP sikungatsimikizidwe. Zitsanzo za nthawi zimaphatikizanso kuyerekezera koyambilira kwa uinjiniya kuchedwa kutengera zomwe zasinthidwa posachedwa. Mitundu yanthawi imatha kusintha pomwe kuyezetsa kwa silicon kumapangitsa kulumikizana pakati pa silicon yeniyeni ndi mitundu yanthawi. Mutha kugwiritsa ntchito maziko a IP awa pamapangidwe adongosolo ndi maphunziro ogwiritsira ntchito zida, kuyerekezera, kuwunika, kuwunika kwanthawi yayitali, kuunika kwanthawi yoyambira (bajeti yamapaipi), ndi njira yosinthira I/O (m'lifupi mwanjira ya data, kuya kwakuya, miyeso ya I/O). ).
- Thandizo loyambirira—Intel imatsimikizira IP core ndi mitundu yoyambira nthawi ya banja la chipangizochi. IP core imakwaniritsa zofunikira zonse, koma mwina ikuwunikabe nthawi ya banja la chipangizocho. Mutha kuzigwiritsa ntchito popanga mapangidwe mosamala.
- Thandizo lomaliza—Intelverifies IP core yokhala ndi mitundu yomaliza yanthawi yabanja la chipangizochi. IP core imakwaniritsa zofunikira zonse zogwirira ntchito komanso nthawi ya banja la chipangizocho. Mutha kuzigwiritsa ntchito pakupanga mapangidwe.
Malingaliro a kampani Intel Corporation Maumwini onse ndi otetezedwa. Intel, logo ya Intel, ndi zizindikiro zina za Intel ndi zizindikiro za Intel Corporation kapena mabungwe ake. Intel imatsimikizira kugwira ntchito kwa FPGA yake ndi zida za semiconductor malinga ndi zomwe zili pano malinga ndi chitsimikizo cha Intel, koma ili ndi ufulu wosintha zinthu ndi ntchito zilizonse nthawi iliyonse popanda kuzindikira. Intel sakhala ndi udindo kapena udindo chifukwa cha kugwiritsa ntchito kapena kugwiritsa ntchito zidziwitso zilizonse, malonda, kapena ntchito zomwe zafotokozedwa pano kupatula monga momwe Intel adavomerezera momveka bwino. Makasitomala a Intel amalangizidwa kuti apeze mtundu waposachedwa kwambiri wamakina a chipangizocho asanadalire zidziwitso zilizonse zosindikizidwa komanso asanayike maoda azinthu kapena ntchito. *Mayina ena ndi mtundu zitha kunenedwa kuti ndi za ena.

Ntchito ya SinCos
ALTERA_CORDIC IP Core User Guide 683808 | 2017.05.08
Ntchitoyi imathandizira masinthidwe awiri, kutengera chizindikiro cha a:
- Ngati a wasainidwa, mzere wololeza wololedwa ndi [-π+π] ndipo zotulutsa za sine ndi cosine ndi ∈[−1,1].
- Ngati a sichinasayinidwe, IP core imangolowetsa ku [0+π/2] ndikuchepetsa zotulutsa ku [0,1].
Ntchito ya Atan2
Imawerengera ntchitoyi atan2(y, x) kuchokera pazolowetsa y ndi x.
Ntchito ya Atan2
- Ngati x ndi y asainidwa, IP core ndiyomwe imayang'anira zolowetsa kuchokera pamitundu yokhazikika.
- Zotulutsa ndi [-π+π].
Vector Translate Ntchito
Ntchito yomasulira vekitala ndikuwonjezera kwa ntchito ya atan2. Imatulutsa kukula kwa vekitala yolowetsa ndi ngodya a=atan2(y,x).
Vector Translate Ntchito
Ntchitoyi imatenga zolowetsa x ndi y ndikutulutsa a=atan2(y, x) ndi M = K(x2+y2)0.5. M ndi kukula kwa vekitala v=(x,y)T, yosinthidwa ndi CORDIC yokhazikika yomwe imasinthira ku 1.646760258121, yomwe ili yodutsa, motero ilibe mtengo wokhazikika. Ntchitozi zimathandizira masinthidwe awiri, kutengera chizindikiro cha x ndi y:
- Ngati zolowetsazo zasainidwa, mawonekedwewo amapereka mtundu wololeza wololedwa. Mu kasinthidwe aka mtundu wotuluka wa a is∈[−π+π]. Kutulutsa kwa M kumatengera kuchuluka kwa x ndi y, malinga ndi kukula kwake.
- Ngati zolowetsazo sizinasaine, IP core imaletsa kutulutsa kwa [0+π/2]. Kukula kumadalirabe fomula.
Ntchito ya Vector Rotate
Vector rotating ntchito imatenga vekitala v= (x,y)T yoperekedwa ndi ma coordinates x ndi y ndi ngodya a. Ntchitoyi imapanga kasinthasintha kofanana kwa vekitala v ndi ngodya a kuti apange vekitala v0=(x0,y0)T.
Ntchito ya Vector Rotate
Kuzungulirako ndikuzungulira kofanana chifukwa kukula kwa vector v0 yopangidwa kumakulitsidwa ndi CORDIC yeniyeni yokhazikika K(˜1.646760258121). Ma equation a ma coordinates a vector v0 ndi awa:
- x0 = K(xcos(a)−ysin(a))
- y0 = K(xsin(a)+ ycos(a))
Ngati muyika chizindikiro kuti chikhale chowona pa zolowetsa za x,y pa ntchitoyi, IP core imaletsa kuchuluka kwake ku [-1,1]. Mumapereka chiwerengero cha magawo ang'onoang'ono. Makona olowetsamo a amaloledwa mumsinkhu [−π+π], ndipo ali ndi nambala yofanana ya tizigawo ting'onoting'ono monga zolowetsa zina. Mumapereka magawo ang'onoang'ono ndipo m'lifupi mwake ndi w=wF+3, yosainidwa. Pazolowetsa zosasainidwa x,y, IP core imangopatsa [0,1], ngodya a mpaka [0,π].
