摘要

本文提出了一种高性能的降尺度器，利用插值滤波来提高降尺度图像的质量。它利用数字滤波器的非线性相位特性来降低硬件复杂度。实现的架构由四个块组成:(i)行存储器，(ii)带插值滤波器的垂直缩放器，(iii)带插值滤波器的水平缩放器，以及(iv) FIFO。采用0.65 /spl μ m CMOS工艺制备。

High Resolution Image Scaler Using Interpolation Filter For Multimedia Video Applications

This paper proposes a high-performance down scaler to improve the quality of a down-scaled image using interpolation filter. It uses a non-linear phase property of the digital filter to reduce hardware complexity. The implemented architecture is composed of four blocks: (i) line memory, (ii) vertical scaler with interpolation filter, (iii) horizontal scaler with interpolation filter, and (iv) FIFO. It has been fabricated by using 0.65 /spl mu/m CMOS process.
