I-Native Loopback Accelerator Functional Unit (AFU)

I-Native Loopback (NLB) AFU Overview

I-NLB sampAma-AFU ahlanganisa isethi ye-Verilog ne-System Verilog files ukuhlola ukufunda nokubhala inkumbulo, umkhawulokudonsa, kanye ne-latency.

Le phakheji ihlanganisa ama-AFU amathathu ongawakha emthonjeni ofanayo we-RTL. Ukucushwa kwakho kwekhodi yomthombo we-RTL kudala lawa ma-AFU.

I-NLB SampUmsebenzi we-Accelerator (AF)
I-$OPAE_PLATFORM_ROOT/hw/sampLes directory igcina ikhodi yomthombo yalezi NLB ezilandelayoampama-AFUs:

nlb_mode_0
nlb_mode_0_stp

nlb_mode_3

Qaphela: I-$DCP_LOC/hw/sampLes directory igcina i-NLB sampIkhodi yomthombo ye-AFUs yephakheji yokukhishwa kwe-1.0.

Ukuqonda i-NLB sample AFU yesakhiwo sekhodi yomthombo kanye nendlela yokuyakha, bheka enye yalezi Ziqondiso Zokuqala Ezisheshayo (kuye ngokuthi iyiphi i-Intel FPGA PAC oyisebenzisayo):

Uma usebenzisa i-Intel PAC nge-Intel Arria® 10 GX FPGA, bheka i-IntelProgrammable Acceleration Card ene-Intel Arria 10 GX FPGA.

Uma usebenzisa i-Intel FPGA PAC D5005, bheka ku-Intel Acceleration Stack Quick Start Guide ye-Intel FPGA Programmable Acceleration Card D5005.

Iphakheji yokukhulula ihlinzeka ngama-s amathathu alandelayoampama-AFs:

Imodi ye-NLB 0 AF: idinga i-hello_fpga noma insiza ye-fpgadiag ukwenza uhlolo lwe-lpbk1.
Imodi ye-NLB 3 AF: idinga insiza ye-fpgadiag ukwenza ukuphazamisa, ukufunda, nokubhala izivivinyo.

Imodi ye-NLB engu-0 stp AF: idinga i-hello_fpga noma insiza ye-fpgadiag ukwenza uhlolo lwe-lpbak1.
Qaphela: I-nlb_mode_0_stp iyi-AFU efanayo ne-nlb_mode_0 kodwa inesici sokususa iphutha se-Signal Tap esinikwe amandla.
Izinsiza ze-fpgadiag ne-hello_fpga zisiza i-AF efanelekile ukuthi ihlonze, ihlole futhi ibike ngehadiwe ye-FPGA.

Izindlela Zokuhlola
I-CSR_CFG[4:2] ilungiselela imodi yokuhlola. Izivivinyo ezine ezilandelayo ziyatholakala:

I-LPBK1: Lokhu ukuhlola ikhophi yenkumbulo. I-AF ikopisha CSR_NUM_LINES ukusuka kusigcinalwazi somthombo kuya kubhafa yendawo. Lapho ukuhlolwa sekuqediwe, isofthiwe iqhathanisa umthombo kanye namabhafa endawo.
Funda: Lokhu kuhlolwa kugcizelela indlela efundwayo futhi kulinganise umkhawulokudonsa wokufunda noma ukubambezeleka. I-AF ifunda CSR_NUM_LINES kusukela ku-CSR_SRC_ADDR. Lokhu ukuhlola komkhawulokudonsa noma ukubambezeleka kuphela. Ayiqinisekisi idatha efundiwe.
Bhala: Lokhu kuhlolwa kugcizelela indlela yokubhala futhi kulinganise umkhawulokudonsa noma ukubambezeleka. I-AF ifunda CSR_NUM_LINES kusukela ku-CSR_SRC_ADDR. Lokhu ukuhlola komkhawulokudonsa noma ukubambezeleka kuphela. Ayiqinisekisi idatha ebhaliwe.
TRPUT: Lesi sivivinyo sihlanganisa ukufunda nokubhala. Ifundeka ngokuthi CSR_NUM_LINES kusukela endaweni ye-CSR_SRC_ADDR futhi ibhala CSR_NUM_LINES kuya ku-CSR_SRC_ADDR. Iphinde ilinganise umkhawulokudonsa wokufunda nokubhala. Lokhu kuhlola akuyihloli idatha. Ukufunda nokubhala akuncikile

Ithebula elilandelayo libonisa umbhalo wekhodi we-CSR_CFG wezivivinyo ezine. Leli thebula liyasetha futhi CSR_NUM_LINES, =14. Ungashintsha inombolo yemigqa yenqolobane ngokubuyekeza irejista ye-CSR_NUM_LINES.

Ithebula 8. Izindlela Zokuhlola

I-FPGA Diagnostics: fpgadiag
Insiza ye-fpgadiag ifaka phakathi izivivinyo ezimbalwa zokuxilonga, ukuhlola, kanye nokubika ngehadiwe ye-FPGA. Sebenzisa insiza ye-fpgadiag ukusebenzisa zonke izindlela zokuhlola. Ukuze uthole ulwazi olwengeziwe mayelana nokusebenzisa insiza ye-fpgadiag, bheka isigaba se-fpgadiag kumhlahlandlela wamathuluzi we-Open Programmable Acceleration Engine (OPAE).

Imodi ye-NLB0 Hello_FPGA Test Flow

Isoftware iqalisa iMemori Yesimo Sedivayisi (DSM) iye kuziro.
Isoftware ibhala ikheli le-DSM BASE ku-AFU. I-CSR Bhala(DSM_BASE_H), CSRWrite(DSM_BASE_L)
Isofthiwe ilungiselela umthombo kanye nesigcinalwazi sememori yendawo. Lokhu kulungiselelwa kuqondene nokuhlolwa.
Isofthiwe ibhala CSR_CTL[2:0]= 0x1. Lokhu kubhala kuletha uhlolo ekusethwe kabusha futhi kumodi yokumisa. Ukulungiselela kungaqhubeka kuphela uma CSR_CTL[0]=1 & CSR_CTL[1]=1.

I-Software ilungisa imingcele yokuhlola, njenge-src, i-destaddress, i-csr_cfg, imigqa yenombolo, njalonjalo.
I-CSR yesofthiwe ibhala i-CSR_CTL[2:0]= 0x3. I-AF iqala ukwenza ukuhlolwa.
Ukuqedwa kokuhlolwa:
- Izingxenyekazi zekhompyutha ziyaphela lapho ukuhlola kuqeda noma kuthola iphutha. Uma sekuqediwe, i-AF hardware ibuyekeza i-DSM_STATUS. Ama-poll esofthiwe DSM_STATUS[31:0]==1 ukuthola ukuqedwa kokuhlolwa.
- Isofthiwe ingaphoqelela ukuqedwa kokuhlolwa ngokubhala i-CSR ibhala CSR_CTL[2:0]=0x7. I-Hardware AF ibuyekeza i-DSM_STATUS.
