Intel inopa anotevera dhizaini mazinga eIntel FPGA IP cores:
- Rutsigiro rwepamberi-iyo IP musimboti unowanikwa kuti uedze uye uunganidze mhuri yemudziyo uyu. FPGA chirongwa file (.pof) tsigiro haiwanikwe yeQuartus Prime Pro Stratix 10 Edition Beta software uye sekuvharwa kweIP nguva hakugone kuvimbiswa. Modhi dzenguva dzinosanganisira yekutanga fungidziro yeinjiniya yekunonoka zvichienderana neruzivo rwekutanga post-rongedzo. Iwo mamodhi enguva anogona kushanduka sezvo silicon yekuyedza inovandudza kuwirirana pakati peiyo chaiyo silicon nemhando dzenguva. Iwe unogona kushandisa iyi IP musimboti wehurongwa hwekuvaka uye zviwanikwa zvekushandisa zvidzidzo, simulation, pinout, system latency assessments, basic time assessments (pipeline budgeting), uye I/O transfer strategy (data-nzira upamhi, kuputika kudzika, I/O zviyero tradeoffs. )
- Rutsigiro rwekutanga-Intel inosimbisa iyo IP musimboti ine yekutanga nguva modhi yemhuri yemudziyo uyu. Iyo IP musimboti inosangana nezvose zvinoshanda zvinodiwa, asi inogona kunge ichiri kuongororwa nguva yemhuri yemudziyo. Iwe unogona kuishandisa mune zvigadzirwa zvekugadzira nekuchenjerera.

Iro basa rinotsigira maviri magadzirirwo, zvichienderana nechiratidzo chechiratidzo che:
- Kana a akasainwa, iyo inotenderwa yekuisa renji ndeye [-π+π] uye iyo inobuda renji yesine necosine i ∈[−1,1].
- Kana a isina kusainwa, IP core inoganhura inopinza ku [0+π/2] uye inoganhura iyo inobuda kurengeredzwa ku [0,1].
Atan2 Basa
Inokokorodza basa atan2(y, x) kubva pane zvinopinda y uye x.
Atan2 Basa
- Kana x uye y vakasaina, iyo IP musimboti inosarudza iyo yekuisa renji kubva kune yakatarwa-point mafomati.
- Kubuda kwakaita [-π+π].
Vector Translate Basa
Vector translate function ndeyekuwedzera kweatan2 basa. Inoburitsa ukuru hwevhekita yekupinza uye kona a=atan2(y,x).
Vector Translate Basa
Basa racho rinotora zvinyorwa x uye y uye zvinobuda a=atan2(y, x) uye M = K(x2+y2)0.5. M ndihwo ukuru hwevheji yekupinda v=(x,y)T, yakayerwa neCORDIC chaiyo inoshanduka ichienda ku 1.646760258121, iyo inodarika, saka haina kukosha kwakatarwa. Iwo mabasa anotsigira magadzirirwo maviri, zvichienderana nechiratidzo che x uye y:
- Kana izvo zvakaiswa zvakasainwa, mafomati anopa iyo inotenderwa yekupinza renji. Mukugadzirisa uku rudzi rwekubuda kwe a is∈[−π+π]. Kubuda kweM kunotsamira pakuiswa kwe x uye y, zvichienderana nehukuru fomula.
- Kana zvinoiswa zvisina kusaina, IP core inodzikamisa kukosha kwekubuda kwe [0+π/2]. Kukosha kwehukuru huchiri kuenderana neformula.
Vector Rotate Basa
Vector rotate function inotora vhekita v= (x,y)T yakapihwa nemakonisheni maviri x uye y nekona a. Basa racho rinoburitsa kufanana kutenderera kwevhekita v nekona a kugadzira vheji v0=(x0,y0)T.
Vector Rotate Basa
Iko kutenderera kutenderera kwakafanana nekuti ukuru hweiyo yakagadzirwa vector v0 inokwidziridzwa neCORDIC chaiyo inogara K (˜1.646760258121). Iwo equation emakonisheni evector v0 ndeaya:
- x0 = K(xcos(a)−ysin(a))
- y0 = K(xsin(a)+ ycos(a))
Kana iwe ukaisa chiratidzo chechiratidzo chechokwadi cheiyo x,y mapindiro ebasa racho, iyo IP core inodzikamisa huwandu hwayo ku [-1,1]. Iwe unopa nhamba yezvikamu zviduku. Ekona yekuisa a inotenderwa muchikamu [−π+π], uye ine nhamba yakafanana yemabhiti ezvidimbu semamwe mabhii. Iwe unopa zvakabuda mabhiti uye hupamhi hwese hwezvabuda w=wF+3, yakasainwa. Pazvisina kusainwa x,y, IP core inoganhura huwandu ku [0,1], kona a kusvika ku [0,π].
