ABSTRACT:
A data weighted average circuit is disclosed which includes a lookup unit and a storage unit. The invention uses a lookup table to speed up the circuit operation. Besides, the operation delay is not affected by various orders of the data weighted average circuit and various bit-widths of input data.
