4.4. FIR II IP Core Multichannel Operation
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.
