I-27 × i-27 ye-Architecture yeModi
Iimodyuli ezinokukhethwa
Iimodyuli ozikhethelayo ezifumaneka kwiCyclone 10 GX Native Fixed Point DSP IP Core zezi:
- Igalelo le-cascade
- Ii-adali zangaphambili
- I-Coefficient yangaphakathi
- I-Accumulator kunye nemveliso ye-cascade
- Iirejista zombhobho
Igalelo leCascade
Igalelo leCascade lixhaswa kwi-ay nangebhasi yokungenisa. Xa useta Vuselela igalelo le-cascade ye-'ay' igalelo ku-Ewe, iCyclone 10 GX Native Fixed Point DSP IP core iya kuthatha igalelo kwi-scan input signals endaweni ye-ay input bus. Xa useta Yenza i-Cascade ye-Input ye-'by' igalelo ku-Ewe, i-Cyclone 10 GX Native Fixed Point ye-DSP engundoqo iya kuthatha amagalelo kwi-ay input bus endaweni ye-input bus.
Kuyacetyiswa ukuba kwenziwe iirejista zongeniso kwi-ay kunye/okanye nanini na xa i-input cascade yenziwe yasebenza ukwenzela ukuchaneka kwesicelo.
Unokwenza ukuba iirejista zokulibaziseka zihambelane nemfuno yokulinda phakathi kwerejista yokufaka kunye nerejista yokuphuma. Kukho iirejista zokulibaziseka ezi-2 kwindawo engundoqo. Irejista yokulibaziseka ephezulu isetyenziselwa i-ay okanye i-scan-in input port ngelixa irejista yokulibaziseka esezantsi isetyenziselwa izibuko zemveliso ye-scaout. Ezi rejista zokulibaziseka zixhaswa kwi-18 × 18 imodi epheleleyo, i-18 × 18 sums of 2 modes, kunye ne-18 × 18 iindlela ze-systolic.
I-pre-adder
I-pre-adder inokumiselwa kolu lungelelwaniso lulandelayo:
- Ii-add ezimbini ezizimeleyo ze-18-bit (zisayiniwe/ ezingasayinwanga).
- Enye ye-26-bit yangaphambili ye-adder.
Xa uvumela i-pre-adder kwi-18 × 18 iindlela zokuphindaphinda, i-ay kunye ne-az zisetyenziswa njenge-adder yongeniso kwi-adder ephezulu ngelixa i-bz isetyenziswa njenge-bz yongeniso kwi-adder esezantsi. Xa uvumela i-pre-adder kwimo yophindaphindo lwe-27 × 27, i-ay kunye ne-az zisetyenziswa njenge-adder yokufaka kwi-adder yangaphambili. I-pre-adder ixhasa imisebenzi yokudibanisa kunye nokuthabatha. Xa zombini ii-pre-adders ngaphakathi kwebhloko ye-DSP efanayo zisetyenziswa, kufuneka babelane ngohlobo olufanayo lokusebenza (nokudibanisa okanye ukuthabatha).
I-Coefficient yangaphakathi
I-coefficient yangaphakathi inokuxhasa ukuya kwii-coefficients ezisibhozo eziqhubekayo kwii-multiplicands kwiimowudi ze-18-bit kunye ne-27-bit. Xa uvumela uphawu lwangaphakathi lwe-coefficient, iibhasi ezimbini zokufaka ukulawula ukukhethwa kwe-coefficient multiplexer ziya kuveliswa. Ibhasi yokufaka icoefsela isetyenziselwa ukukhetha i-coefficients echazwe kwangaphambili yesiphindaphindesi esiphezulu kwaye ibhasi yegalelo lomcebisi isetyenziselwa ukukhetha i-coefficients echazwe kwangaphambili yesiphindaphindi esisezantsi.
Ukugcinwa kwe-coefficient yangaphakathi ayixhasi amaxabiso e-coefficient alawulekayo kunye nokugcinwa kwe-coefficient yangaphandle kuyadingeka ukwenza umsebenzi onjalo.
I-Accumulator kunye ne-Cascade yokuPhuma
Imodyuli ye-accumulator inokwenziwa ukuba yenze imisebenzi elandelayo:
- Umsebenzi wokongezwa okanye wokuthabatha
- Umsebenzi wokurhangqa onomkhethe usebenzisa ixabiso elingaguqukiyo le-2N
- Ukuqokelelwa kwamatshaneli amabini
Ukwenza umsebenzi wokudibanisa okanye wokuthabatha we-accumulator ngokuguquguqukayo, lawula isignali yegalelo elichasayo. Ngomsebenzi wokurhangqa onomkhethe, ungakhankanya kwaye ulayishe ukucwangciswa kwangaphambili okungaguqukiyo kwe-2N phambi kokuba imodyuli yesiqokeleli yenziwe ngokukhankanya inani elipheleleyo kwiparameter N ixabiso lokusetwa kwangaphambili okungaguqukiyo. Inani elipheleleyo elingu-N kufuneka libe ngaphantsi kwama-64. Ungenza ngamandla okanye uvale usetyenziso lokusetwa kwangaphambili ngokungaguqukiyo ngokulawula isignali ye-loadconst. Ungasebenzisa lo msebenzi njenge-muxing esebenzayo yexabiso elijikelezileyo kwindlela yengxelo ye-accumulator. Iindleko ezilayishiweyo kunye nokusetyenziswa komqondiso oqokelelweyo kuxhomekeke ngokufanayo.
Unokwenza irejista ye-accumulator ephindwe kabini usebenzisa iparameter Yenza i-accumulator ephindwe kabini ukwenza ukuqokelela kabini. Imodyuli ye-accumulator inokuxhasa ukudibanisa kweebhloko ezininzi ze-DSP zokongezwa okanye ukuthabatha imisebenzi ngokuvumela i-port ye-chain input kunye ne-chain-out output port. Kwimo ye-18 × 18 ye-systolic, kuphela i-44-bit ye-chain input bus kunye ne-chain out output bus iya kusetyenziswa. Nangona kunjalo, onke amatyathanga angama-64 kwibhasi yokufaka kufuneka aqhagamshelwe kwibhasi ye-chain-out yebhasi ukusuka kwibhloko ye-DSP eyandulelayo.
Irejista yemibhobho
I-Cyclone 10 GX Native Fixed Point DSP engundoqo ixhasa inqanaba elinye lerejista yombhobho. Irejista yombhobho ixhasa ukuya kuthi ga kwimithombo yewotshi emithathu kunye nesignali enye ecacileyo yeasynchronous ukuseta ngokutsha iirejista zemibhobho. Kukho iirejista zemibhobho ezintlanu:
- irejista yebhasi yombhobho wokufakwa kwedatha
- irejista yombhobho yolawulo oluguquguqukayo
- Chaza irejista yombhobho yolawulo oluguqukayo
- qokelela irejista yombhobho yolawulo oluguqukayo
- irejista yombhobho yolawulo lweloadconst
Unokukhetha ukwenza iirejista zemibhobho yebhasi nganye igalelo kunye nerejista yombhobho wolawulo oluguquguqukayo ngokuzimeleyo. Nangona kunjalo, zonke iirejista zemibhobho esebenzayo kufuneka zisebenzise umthombo ofanayo wewotshi.
