Abstract:
A hybrid FIR filter includes a plurality of FIR filter units arranged as Direct Form FIR filters, connected together in an arrangement similar to a Transpose Form FIR filter. The hybrid filter arrangement may be used to configure a larger FIR filter in a programmable logic device having one or more specialized functional blocks, incorporating multipliers and adders, that are particularly well-suited for configuration as small Direct Form FIR filters.
