Abstract
OpenVG and SVG Tiny are the most widely used 2D vector graphics technologies for outputs in the various embedded environments including smart phones. Especially, to show high refresh rates on the high resolution screens, it is necessary to effectively accelerate them. Until now, OpenVG and SVG Tiny are available as hardware implementations such as the fully-dedicated graphics chips or full software implementations. Currently available vector graphics silicon chips are relatively expensive and require high power consumption. In contrast, previous full software implementations show lower performance even with almost 100% CPU usages, which would disrupt other multi-threaded applications, In this paper, we present a cost-effective way of accelerating both of OpenVG and SVG Tiny, based on the multimedia-processing hardware, which is wide-spread on the media devices and mobile phones. Through the effective use of these multimedia processors, we successfully accelerated OpenVG and SVG Tiny at least 3.5 times to at most 30 times, even with lower power consumption and lower CPU usage.
