By developing a generalized 1D approach and parallel computing algorithm, this paper presents a parallel algorithm design and hardware implementation for the computation of 4\_4 DCT. This algorithm sorts all the 2D input pixel data into four groups. Each group is then forwarded to a 1D DCT arithmeti
