The DSPLib contains several variants of Finite Impulse Response (FIR) filters. These include single-rate FIRs, half-band interpolation/decimation FIRs, as well as integer and fractional interpolation/decimation FIRs for AIE. AIE-ML devices have support for only the single rate FIRs. Differences in hardware lead to different constraints and implementations for FIRs in each device.
