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.
