HSP43168 Datasheet | Intersil

Data Sheet November 1999 File Number 2808.8 Dual FIR Filter The HSP43168 Dual FIR Filter consists of two independent 8-tap FIR filters. Each filter supports decimation from 1 to 16 and provides on-board storage for 32 sets of coefficients. The Block Diagram shows two FIR cells each fed by a separate coefficient bank and one of two separate inputs. The outputs of the FIR cells are either summed or multiplexed by the MUX/Adder. The pute power in the FIR Cells can be configured to provide quadrature filtering, plex filtering, 2-D convolution, 1-D/2-D correlations, and interpolating/decimating filters. The FIR cells take advantage of symmetry in FIR coefficients by pre-adding data...
