Abstract
Finite impulse response filtering is achieved by broadcasting to at least one compute unit an instruction having a plurality of data samples, a conditional field associated with each compute unit, and a set of operator values for operating on each data sample; providing a function of each the data sample in accordance with an associated set of operator values identified by the conditional field; and combining the functions to obtain an intermediate finite impulse response of the data samples.
