An Optimized Rendering Algorithm for Hardware Implementation of OpenVG 2D Vector Graphics

Abstract

An optimized rendering algorithm of the OpenVG 2D vector graphics for hardware implementation is presented in this paper. In the rendering algorithm we adopted a hybrid of raster and vector rendering, which uses vector rendering only within each scanline, to reduce both the number of external memory accesses and the computational complexity. We implemented a hardware accelerator with the proposed algorithm. Experimental results show that our hardware accelerator can handle 11.8 fps of Tiger image for a QVGA panel at the operating clock frequency of 100 MHz.
