摘要：
In this paper, we propose a deeply parallel architecture called Fragment-based Interleaving Dual Pipelines(FIDP) which can exploit all parallelisms in Lifting-based 2D DWT algorithm. FIDP adopts a fragment-based samples consumption policy and consists of two row processors and two column processors. These processors are organized as interleaving dual pipelines to operate effectively. FIDP takes N-2/4+N/2+1 cycles to finish a N x N 2D DWT while requires only 5N+2 buffer.
