Mo te Fronthaul Compression Intel® FPGA IP

Ko te Fronthaul Compression IP kei roto i te pupuhi me te whakahekenga mo nga raraunga U-rererangi IQ. Ka tātaihia e te pūkaha kōpeke te µ-law, te paraka ranei te kōpeketanga ira mānu i runga i te pane kōpeketanga raraunga kaiwhakamahi (udCompHdr). Ka whakamahia e tenei IP tetahi atanga roma Avalon mo nga raraunga IQ, nga tohu hiko, me nga tohu metadata me nga tohu taha taha, me te atanga mahere-maamahara Avalon mo te mana whakahaere me nga rehita mana (CSRs).
