A High-Performance OpenVG Accelerator with Dual-Scanline Filling Rendering
In this paper, we propose a new search
algorithm that reduces the memory bandwidth required for
finding active edges in OpenVG rendering. It simultaneously
prepares an active edge table for each scanline so that one
edge may be stored in several active edge tables, which
depends on the lifetime of each edge. It also gives us another
benefit so that we can implement the multiple scanline filling
in parallel for performance improvement. Experimental
results show the external memory accesses of the proposed
algorithm can be substantially reduced and the performance
of the proposed dual-scanline filling rendering architecture
can be significantly increased, especially for high-quality
images. We implemented an OpenVG accelerator using the
dual-scanline filling rendering with one-poly four-metal 0.18-
μm CMOS technology, which requires about 350K gates and
operates at 100 MHz.This work was supported by System IC2010 project of
