Classification: CPC H | IPC H

Claim 17:
18. A Scalable Finite Impulse Response (“SFIR”) filter comprising:
a pre-processing section;
a post-processing section; and
a finite impulse response (“FIR”) Matrix coupled to the pre-processing section and the post-processing section, wherein the FIR Matrix comprises:
a plurality of filter taps, each filter tap of the plurality of filter taps having at least:
a first input;
a second input;
a multiplexer coupled to the first input and the second input;
a first flip-flop coupled to an output of the multiplexer;
a second flip-flop;
a multiplier coupled between the first flip-flop and an adder, the multiplier being directly coupled to the adder;
the adder coupled between the second flip-flop and the multiplier, the adder receiving output directly from the second flip flop and the adder receiving output directly from the multiplier; and

a plurality of signal paths arranged to allow re-configurable data throughput between each filter tap of the plurality of filter taps;
wherein the SFIR filter is configured to operate as an interpolator and comprises the pre-processing section configured as a fan-out device and the post-processing section configured as a re-order device.
