Overview

The JPEG2K-E core is a complete high performance JPEG2000 - ISO/IEC 15444-1 image compression solution targeted for video and high bandwidth image compression applications.

The JPEG2k-E core delivers real JPEG2000 compression efficiency. Commonly used hardware simplification compromises, such us bypass and parallel mode of the entropy coding process, that damage the JPEG2000 rate-distortion efficiency have not been adopted. Furthermore the core implements an accurate rate-control that delivers quality practically equivalent to de-facto software encoders. Region of interest coding, progressive streams with multiple quality layers, lossy and lossless compression are JPEG2000 standard benefits also delivered from the JPEG2k-E core.

A single JPEG2k-E core can process mutliple Full HD (1080p@30) channels, as for example it supports an input rate of 190 MSamples/sec when mapped on a 90nm ASIC technology. Users of the core can use parallel instantiations to meet the processing rate requirements even of the most demanding applications.

The JPEG2K-E is a reliable and easy-to-integrate core as it is carefully designed, rigorously verified, and production proven. The architecture can be fine-tuned based on the application specific needs. Ease of integration is served by a complete verification environment, and additional aids for system on chip simulation, such as a software bit-accurate model.
