In one embodiment, the present invention discloses an apparatus (600) and method for providing efficient implementations of Finite Impulse Response (FIR) digital filters (605). Specifically, a result from a FIR digital filter can be efficiently computed by using an AVG operation or instruction in conjunction with one or more other operations. The unique use of the AVG operation will allow FIR filters of various types, e.g., Types 1-4, to significantly reduce computational cycles.
