High-Level Synthesis of a Unified 2-D DWT System Architecture for JPEG2000 Using FPGAs

In this paper, a programmable 2-D DWT system architecture designed for the JPEG2000 standard is proposed. The proposed system architecture, developed through an iterative design space exploration methodology using Altera´s C2H compiler, provides a significant 2-D DWT performance improvement when compared to an optimized 2-D DWT software implementation and is capable of real-time video processing performance for high resolution grayscale images up to 1280 × 720 (720p) when synthesized and benchmarked in an Altera DE3 Stratix III FPGA board.
