Native Loopback Accelerator Functional Unit (AFU)
Native Loopback (NLB) AFU Overview
- Mbiri ya NLBample AFUs imakhala ndi Verilog ndi System Verilog files kuyesa kukumbukira kuwerenga ndi kulemba, bandwidth, ndi latency.
- Phukusili likuphatikiza ma AFU atatu omwe mungapange kuchokera kugwero lomwelo la RTL. Kusintha kwanu kwa code ya RTL kumapanga ma AFU awa.
Mbiri ya NLB Sample Accelerator Function (AF)
The $OPAE_PLATFORM_ROOT/hw/samples directory imasunga ma code a NLB otsatirawaampndi AFUs:
- nlb_mode_0
- nlb_mode_0_stp
- nlb_mode_3
Zindikirani: The $DCP_LOC/hw/samples directory amasunga ma NLB sample AFUs source code ya phukusi lotulutsidwa la 1.0.
Kuti mumvetsetse NLB sample AFU source code code ndi momwe mungamangire, tchulani imodzi mwazotsatira Zachangu Zoyambira (kutengera Intel FPGA PAC yomwe mukugwiritsa ntchito):
- Ngati mukugwiritsa ntchito Intel PAC yokhala ndi Intel Arria® 10 GX FPGA, tchulani IntelProgrammable Acceleration Card yokhala ndi Intel Arria 10 GX FPGA.
- Ngati mukugwiritsa ntchito Intel FPGA PAC D5005, tchulani Intel Acceleration Stack Quick Start Guide ya Intel FPGA Programmable Acceleration Card D5005.
Phukusi lomasulidwa limapereka ma s atatu otsatirawaampndi AFs:
- NLB mode 0 AF: imafuna hello_fpga kapena fpgadiag zofunikira kuti muyese lpbk1.
- NLB mode 3 AF: imafuna kugwiritsa ntchito fpgadiag kuti iwononge, kuwerenga, ndi kulemba mayeso.
- NLB mode 0 stp AF: imafuna hello_fpga kapena fpgadiag zofunikira kuti muyese lpbak1.
Zindikirani: Nlb_mode_0_stp ndi AFU yofanana ndi nlb_mode_0 koma ndi mawonekedwe a Signal Tap debug.
Zida za fpgadiag ndi hello_fpga zimathandiza AF yoyenera kuzindikira, kuyesa ndi kupereka lipoti pa zida za FPGA.
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.
