Problem with FIR II core

Hello, I am trying to use 11 taps symmetrical FIR using the IP Catalog in Quartus 14.1 My data are in signed Q.15 format with sampling rate 288MHz. I get the data in packets of 4 samples (...

I see.

Actually my output should be passed the same way I get it (4 consecutive samples at once on each 72Mhz tick).

My current system is using 72MHz clock.

The odd/even structure you have in mind is something similar as the polyphase filter decomposition from the multi rate theory I guess?
