Abstract
We propose a software tool for automatic generation of hardware accelerators for performing Discrete Wavelet Transform (DWT) with various coefficient parameters. In addition to (5, 3) and (9, 7) DWT filters defined in the JPEG2001 image compression standa胠ˊ胬ˊ胸ˊ??ð胠ˊ胬ˊ胸ˊ??ð胠ˊ胬ˊ胸ˊ??ð胠ˊ胬ˊ胸ˊ??ð胠ˊ胬ˊ胸ˊ??perform both forward and inverse transform (FDWT and IDWT). Our tool also produces on-chip-bus interface circuit compliant with the AMBA protocol and associated device driver so that the generated IPs are ready for SOC integration. We verify the proposed approach by integrating generated IPs into an SOC platform running JPEG2000 application software. Experimental results demonstrated that the proposed approach is indeed effective in enhancing the productivity of hardware accelerator IP design. The generalization portion is omitted from this paper due to page limitation.
