Claim 10:
11. A method for use with an integrated circuit to implement a feature extraction pipeline including a plurality of pipeline stages, the method comprising:
at each pipeline stage of the plurality of pipeline stages:
receiving a plurality of input symbols;
for each input symbol of the plurality of input symbols, determining whether the input symbol satisfies a condition encoded in a plurality of setting bits; and
when the input symbol satisfies the condition, incrementing an accumulator value of an accumulator, wherein:
the condition encoded in the plurality of setting bits of a dependent pipeline stage of the plurality of pipeline stages includes a conditional dependency on whether a respective prior condition of a prior pipeline stage is satisfied; and
the feature extraction pipeline is configured to output the plurality of accumulator values of the plurality of accumulators included in the pipeline stages.
