<p>A pipeline dprocessing computation apparatus for performing the Butterfly operation on complex data (A, B) as weighted by a complex factor (W) in accordance with the equations X = A + WB Y = A - WB in which partial products for subsequent data (A1, B1) weighted by a factor (W1) are obtained while the sum and difference of A and WB are obtained. In a preferred embodiment the total operation for one set of data is eleven clock cycles, and three sets of data can be operated on concurrently whereby two inputs are provided and two outputs obtained every four cycles.</p> |
