Abstract
An apparatus to perform symmetric filtering image compression is provided. The apparatus includes an N-element shift circuit, that has N shifting blocks (SB), to store and shift data elements. Each data element represents a pixel of an image. The apparatus also includes a first plurality of adder circuits to add data elements from a first plurality of pairs of SBs of the N SBs. The apparatus further includes a second plurality of adder circuits to add data elements from a second plurality of pairs of SBs of the N SBs. Additionally, the apparatus includes a first plurality of multiplier circuits, to multiply by corresponding low pass coefficients results of additions performed by the first plurality of adder circuits. The apparatus also includes a second plurality of multiplier circuits, to multiply by corresponding high pass coefficients results of additions performed by the second plurality of adder circuits.
