13.1.2.2. Reconfigurable FIR Filters
The input rate determines the bandwidth of the FIR. If you turn off Reconfigurable carrier (nonreconfigurable FIR), the IP core allocates this bandwidth equally amongst each channel. The reconfigurable FIR feature allows the IP core to allocate the bandwidth manually. You set these allocations during parameterization and you can change which allocation the IP core uses at run-time using the mode signal. You can use one channel's bandwidth to process a different channel's data. You specify the allocation by listing the channels you want the IP core to process in the mode mapping. For example, a mode mapping of 0,1,2,2 gives channel 2 twice the bandwidth of channel 0 and 1, at the cost of not processing channel 3.
