4.4. FIR II IP Core Multichannel Operation

You can build multichannel systems directly using the required channel count, rather than creating a single channel system and scaling it up. The IP core uses vectors of wires to scale without having to cut and paste multiple blocks.

You can vectorize the FIR II IP core. If data going into the block is a vector requiring multiple instances of a FIR filter, the IP core creates multiple FIR blocks in parallel behind a single FIR II IP core block. If a decimating filter requires a smaller vector on the output, the data from individual filters is automatically time-division multiplexed onto the output vector. You do not have to join filters together with custom logic.
