Za Fronthaul Compression Intel® FPGA IP

Fronthaul Compression IP imakhala ndi kuponderezana ndi kutsika kwa data ya U-ndege IQ. Injini yophatikizira imawerengera µ-lamulo kapena kutsekereza kwa malo oyandama kutengera mutu wa wogwiritsa ntchito data (udCompHdr). IP iyi imagwiritsa ntchito mawonekedwe osinthira a Avalon a data ya IQ, ma siginecha a conduit, ndi ma metadata ndi ma sigino am'mbali, ndi mawonekedwe a Avalon memory-mapped for control and status registry (CSRs).
Mamapu a IP adaphatikizira ma IQs ndi parameter ya compression data (udCompParam) malinga ndi gawo lamtundu wa payload wotchulidwa mu O-RAN specification O-RAN Fronthaul Control, User and Synchronization Plane Version 3.0 April 2020 (O-RAN-WG4.CUS .0-v03.00). Avalon Streaming sink ndi gwero mawonekedwe deta m'lifupi ndi 128-bits kwa mawonekedwe ntchito ndi 64 bits kwa mawonekedwe zoyendera kuthandizira pazipita compressoin chiŵerengero cha 2:1.

1.1. Fronthaul Compression Intel® FPGA IP Features

• -Law and block yoyandama-point compression ndi decompression
• IQ m'lifupi 8-bit mpaka 16-bit
• Kukonzekera kosasunthika komanso kosinthika kwa mtundu wa U-ndege IQ ndi mutu wopondereza
• Paketi ya Multisections (ngati O-RAN Compliant yayatsidwa)

1.2. Fronthaul Compression Intel® FPGA IP Chipangizo Thandizo la Banja
Intel imapereka magawo otsatirawa othandizira chipangizo cha Intel FPGA IP:

• Thandizo lotsogola-IP ikupezeka kuti iyerekeze ndi kuphatikizira banja la chipangizochi. Pulogalamu ya FPGA file (.pof) chithandizo sichikupezeka pa pulogalamu ya Beta ya Quartus Prime Pro Stratix 10 Edition ndipo motero kutseka kwa nthawi ya IP sikungatsimikizidwe. Zitsanzo za nthawi zimaphatikizanso kuyerekezera koyambilira kwa uinjiniya kuchedwa kutengera zomwe zasinthidwa posachedwa. Mitundu yanthawi imatha kusintha pomwe kuyezetsa kwa silicon kumapangitsa kulumikizana pakati pa silicon yeniyeni ndi mitundu yanthawi. Mutha kugwiritsa ntchito maziko a IP awa pamapangidwe adongosolo ndi maphunziro ogwiritsira ntchito zida, kuyerekezera, kuwunika, kuwunika kwanthawi yayitali, kuunika kwanthawi yoyambira (bajeti yamapaipi), ndi njira yosinthira I/O (m'lifupi mwanjira ya data, kuya kwakuya, miyeso ya I/O). ).
• Thandizo loyambirira-Intel imatsimikizira IP core ndi mitundu yoyambira nthawi ya banja la chipangizochi. IP core imakwaniritsa zofunikira zonse, koma mwina ikuwunikabe nthawi ya banja la chipangizocho. Mutha kuzigwiritsa ntchito popanga mapangidwe mosamala.
• Thandizo lomaliza-Intel imatsimikizira IP ndi mitundu yomaliza ya nthawi ya banja la chipangizochi. IP imakwaniritsa zofunikira zonse zogwirira ntchito komanso nthawi ya banja la chipangizocho. Mutha kuzigwiritsa ntchito pakupanga mapangidwe.

1.3. Kutulutsa Zambiri kwa Fronthaul Compression Intel FPGA IP
Mitundu ya Intel FPGA IP imafanana ndi mitundu ya Intel Quartus® Prime Design Suite mpaka v19.1. Kuyambira mu Intel Quartus Prime Design Suite software version 19.2, Intel FPGA IP ili ndi ndondomeko yatsopano yomasulira.
Nambala ya Intel FPGA IP (XYZ) imatha kusintha ndi mtundu uliwonse wa pulogalamu ya Intel Quartus Prime. Kusintha kwa:

• X ikuwonetsa kukonzanso kwakukulu kwa IP. Mukasintha pulogalamu ya Intel Quartus Prime, muyenera kukonzanso IP.
• Y akuwonetsa kuti IP ili ndi zatsopano. Panganinso IP yanu kuti muphatikizepo zatsopanozi.
• Z ikuwonetsa kuti IP imaphatikizapo zosintha zazing'ono. Panganinso IP yanu kuti ikhale ndi zosinthazi.

Chotchinga chimachepetsa phokoso la quantization, makamaka kwa otsika-ampmawu samples. Chifukwa chake, imachepetsa kukula kwa vector magnitude (EVM) yomwe compression imayambitsa. The aligorivimu compression pafupifupi wodziyimira pawokha mtengo mphamvu. Kungotengera zovuta zolowetsa samples ndi x = x1 + jxQ, mtengo wokwanira wazinthu zenizeni komanso zongoyerekeza za block block ndi:
Pokhala ndi mtengo wokwanira wokwanira wa block block, equation yotsatirayi imatsimikizira mtengo wosinthira kumanzere womwe waperekedwa ku block block:Pomwe bitWidth ndi m'lifupi mwake.
IP imathandizira ma compression ratios a 8, 9, 10, 11, 12, 13, 14, 15, 16.
