Lub 18 × 18 Ntxiv 36 Hom Architecture

Koj yuav tsum teeb tsa Tus Neeg Sawv Cev hom rau hauv qab multipliers y operand kom tsis tau kos npe thaum siv hom no. Thaum lub tsheb npav nkag tsawg dua 36-ntsis hauv hom no, koj yuav tsum muab qhov tsim nyog kos npe txuas ntxiv los ua kom tiav 36-ntsis cov tswv yim.

Siv Tsawg dua 36-ntsis Operand Hauv 18 × 18 Ntxiv 36 hom
Qhov no example qhia yuav ua li cas los teeb tsa Cyclone 10 GX Native Fixed Point DSP IP core siv 18 × 18 Ntxiv 36 hom kev ua haujlwm nrog kos npe 12-ntsis cov ntaub ntawv nkag ntawm 101010101010 (binary) es tsis txhob siv 36-ntsis operand.

1. Teem Cov Ntawv Sawv Cev rau hauv qab tus lej x operand: kos npe.
2. Teem Tus Neeg Sawv Cev hom rau hauv qab tus lej sib npaug y operand: kom tsis tau kos npe.
3. Teem 'bx' input tsheb npav dav rau 18.
4. Teem 'los ntawm' input tsheb npav dav rau 18.
5. Muab cov ntaub ntawv ntawm '111111111111111111' rau bx input npav.
6. Muab cov ntaub ntawv ntawm '111111101010101010' mus rau hauv lub tsheb npav nkag.

18 × 18 Systolic Hom
Hauv 18 × 18 systolic kev ua haujlwm hom, Cyclone 10 GX Native Taag Point DSP IP core ua rau sab saum toj thiab hauv qab multipliers, input systolic register rau sab saum toj multiplier, thiab ib tug saw systolic sau npe rau cov saw hauv input signals. Thaum koj qhib qhov tso zis cascade, hom no txhawb nqa cov zis dav dav ntawm 44 khoom. Thaum koj ua kom lub accumulator feature yam tsis muaj qhov tso zis cascade, koj tuaj yeem teeb tsa cov txiaj ntsig tso tawm dav rau 64 khoom.

Lub 18 × 18 Systolic Hom Architecture

27 × 27 Hom
Thaum teeb tsa raws li 27 × 27 hom, Cyclone 10 GX Native Fixed Point DSP IP core ua rau 27 (kos npe / tsis kos npe) × 27 (kos npe / tsis kos npe) tus lej sib npaug. Lub npav tso zis tuaj yeem txhawb nqa txog 64 khoom nrog accumulator / tso zis cascade enabled. Hom no siv qhov sib npaug ntawm resulta = ax * ay.

Xaiv Modules

Cov kev xaiv modules muaj nyob rau hauv Cyclone 10 GX Native Fixed Point DSP IP Core yog:

• Input cascade
• Pre-adders
• Internal Coefficient
• Accumulator thiab tso zis cascade
• Pipeline sau npe

Input Cascade
Input cascade feature tau txais kev txhawb nqa ntawm ay thiab los ntawm lub tsheb npav nkag. Thaum koj teeb tsa Enable input cascade rau 'ay' input rau Yes, Cyclone 10 GX Native Fixed Point DSP IP core yuav siv cov inputs los ntawm scan input signals es tsis txhob ay input tsheb npav. Thaum koj teeb tsa Enable input cascade rau 'los ntawm' cov tswv yim rau Yog, Cyclone 10 GX Native Fixed Point DSP IP core yuav siv cov tswv yim los ntawm ay input tsheb npav es tsis yog los ntawm lub tsheb npav nkag.

Nws raug nquahu kom qhib cov ntawv sau npe nkag rau ay thiab / lossis los ntawm thaum twg cov tswv yim cascade qhib rau qhov tseeb ntawm daim ntawv thov.

Koj tuaj yeem ua kom lub sijhawm ncua sij hawm kom phim qhov kev xav tau latency ntawm cov ntawv sau npe nkag thiab cov ntawv tso tawm. Muaj 2 ncua kev sau npe hauv cov tub ntxhais kawm. Cov npe ncua sij hawm sab saum toj yog siv rau ay lossis scan-hauv cov chaw nres nkoj thaum lub sijhawm ncua sij hawm hauv qab yog siv rau cov chaw nres nkoj xa tawm. Cov npe ncua sij hawm no tau txais kev txhawb nqa hauv 18 × 18 tag nrho hom, 18 × 18 sums ntawm 2 hom, thiab 18 × 18 systolic hom.

Pre-adder

Lub pre-adder tuaj yeem teeb tsa hauv cov kev teeb tsa hauv qab no:

• Ob tus neeg sab nraud 18-ntsis (kos npe / tsis kos npe) ua ntej ntxiv.
• Ib qho 26-ntsis pre-adder.

Thaum koj qhib pre-adder nyob rau hauv 18 × 18 multiplication hom, ay thiab az yog siv raws li lub tsheb npav nkag mus rau sab saum toj pre-adder thaum los ntawm thiab bz siv raws li lub tsheb npav nkag mus rau hauv qab pre-adder. Thaum koj qhib pre-adder nyob rau hauv 27 × 27 multiplication hom, ay thiab az yog siv raws li lub tsheb npav nkag mus rau lub pre-adder. Lub pre-adder txhawb ob qho tib si ntxiv thiab rho tawm haujlwm. Thaum ob qho tib si pre-adders nyob rau hauv tib lub DSP thaiv yog siv, lawv yuav tsum qhia tib hom kev ua haujlwm (xws li ntxiv lossis rho tawm).

Cov coefficient sab hauv tuaj yeem txhawb nqa txog yim qhov sib txuas tsis tu ncua rau cov sib npaug hauv 18-ntsis thiab 27-ntsis hom. Thaum koj ua kom muaj qhov coefficient sab hauv, ob lub tsheb npav nkag los tswj kev xaiv ntawm coefficient multiplexer yuav raug tsim tawm. Lub tsheb npav coefsela input yog siv los xaiv cov coefficients predefined rau sab saum toj multiplier thiab lub counsel input bus yog siv los xaiv cov predefined coefficients rau hauv qab multiplier.

Internal coefficient cia tsis txhawb dynamically controllable coefficient qhov tseem ceeb thiab sab nraud coefficient cia yuav tsum tau ua xws li ib tug kev khiav hauj lwm.

Accumulator thiab Output Cascade

Lub accumulator module tuaj yeem qhib tau los ua cov haujlwm hauv qab no:

• Ntxiv lossis rho tawm haujlwm
• Biased rounding ua haujlwm siv tus nqi tas li ntawm 2N
• Dual channel tsub zuj zuj

Txhawm rau dynamically ua ntxiv lossis rho tawm haujlwm ntawm lub accumulator, tswj lub teeb liab tawm tswv yim tsis zoo. Rau kev ua haujlwm tsis sib haum xeeb, koj tuaj yeem hais qhia thiab thauj cov preset tas li ntawm 2N ua ntej lub accumulator module tau qhib los ntawm kev qhia tus lej rau qhov ntsuas N tus nqi ntawm qhov preset tas li. Tus lej N yuav tsum tsawg dua 64. Koj tuaj yeem ua kom muaj zog lossis ua haujlwm tsis tu ncua los ntawm kev tswj cov teeb liab loadconst. Koj tuaj yeem siv qhov kev ua haujlwm no ua ib qho kev sib tw ntawm tus nqi puag ncig mus rau hauv txoj kev tawm tswv yim accumulator. Tus nqi thauj khoom thiab kev siv lub teeb liab sib xyaw ua ke yog sib koom ua ke.

Koj tuaj yeem ua kom ob lub accumulator sau npe siv cov parameter Qhib ob lub accumulator los ua ob npaug. Lub accumulator module tuaj yeem txhawb nqa cov chaining ntawm ntau DSP blocks rau kev ntxiv lossis rho tawm haujlwm los ntawm kev ua kom cov chaining input port thiab chain-output port. Nyob rau hauv 18 × 18 systolic hom, tsuas yog 44-ntsis ntawm cov saw input tsheb npav thiab chain output tsheb npav yuav raug siv. Txawm li cas los xij, tag nrho 64-ntsis chains nyob rau hauv lub tsheb npav nkag yuav tsum tau txuas nrog cov saw hlau tawm tawm los ntawm DSP block ua ntej.

Pipeline Sau npe

Lub Cyclone 10 GX Native Fixed Point DSP IP core txhawb nqa ib theem ntawm cov raj xa dej. Lub raj xa dej tso npe txhawb nqa txog peb lub moos qhov chaw thiab ib qho asynchronous meej teeb liab los rov pib dua cov ntawv sau npe. Muaj tsib lub npe pipeline:

• data input bus pipeline register
• sub dynamic tswj teeb liab pipeline register
• negate dynamic tswj teeb liab pipeline register
• sau dynamic tswj teeb liab pipeline register
• loadconst dynamic tswj pipeline register

Koj tuaj yeem xaiv los ua kom txhua cov ntaub ntawv nkag mus rau hauv lub tsheb npav cov raj xa dej npe thiab cov kab hluav taws xob tswj lub cev muaj zog tuaj yeem sau npe ntawm nws tus kheej. Txawm li cas los xij, tag nrho cov ntawv tso npe tso npe yuav tsum siv tib lub moos.

Clocking Scheme

Cov tswv yim, cov raj xa dej, thiab cov ntawv tso tawm tso rau hauv Cyclone 10 GX Native Fixed Point DSP IP core txhawb peb lub moos qhov chaw / pab thiab ob lub asynchronous clears. Txhua cov ntawv sau npe siv aclr[0] thiab tag nrho cov raj xa dej thiab cov ntawv tso tawm siv aclr[1]. Txhua hom kev sau npe tuaj yeem xaiv ib qho ntawm peb lub moos qhov chaw thiab moos ua kom muaj teeb meem. Thaum koj teeb tsa Cyclone 10 GX Native Fixed Point DSP IP core rau 18 × 18 systolic kev ua haujlwm hom, Intel Quartus Prime software yuav teeb tsa cov ntawv sau npe systolic thiab cov saw systolic sau npe moos rau tib lub moos raws li cov khoom tso tawm sau npe sab hauv.

Thaum koj tso cai rau ob lub accumulator feature, Intel Quartus Prime software yuav teeb tsa ob lub accumulator sau npe moos mus rau tib lub moos raws li cov zis tso npe hauv.
