JPEG2K-E JPEG 2000 Compression Encoder Core

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.

The JPEG2K-E can be utilized in a variety of digital imaging applications including:

Block Diagram



The core as delivered is warranted against defects for ninety days from purchase. Thirty days of phone and email technical support are included, starting with the first interaction. Additional maintenance and support options are available.


The core has been verified through extensive synthesis, place and route and simulation runs. It has also been embedded in several products, and is proven in both ASIC and FPGA technologies.  Evaluation boards are available upon request.


The core is available in ASIC (synthesizable HDL) and FPGA (netlist) forms, and includes everything required for successful implementation:
