Claim 18:
19. A Scalable Finite Impulse Response (“SFIR”) filter comprising:
means for pre-processing;
means for post-processing; and
a finite impulse response (“FIR”) filtering matrix coupled to the means for pre-processing and the means for post-processing, wherein the FIR filtering 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 coefficient section directly coupled to a first input of the multiplier, the first input of the multiplier coupled solely to the coefficient section, the coefficient section to solely provide a coefficient; and

a plurality of signal paths, wherein the plurality of signal paths comprises means to allow re-configurable data throughput between each filter tap of the plurality of filter taps.
