Abstract

The realization of new MPEG-4 functionality, applicable to three-dimensional graphics texture compression and image database access over the Internet, is demonstrated on a heterogeneous platform with several unique features. First, applying our system-level design methodologies effectively removes all data transfer and storage overhead that comprises the main bottleneck in the original system description. Second, a first-of-a-kind application specific solution, called Ozone, accelerates the embedded-zero-tree based encoding and is capable of compressing 30 color CIF images per second. The entire application is running on the Ozone coupled to a PC.
