JPEGLS-E JPEG-LS Compression Encoder Core

The JPEGLS-E core is a standalone and high-performance JPEGLS encoder for lossless still image and video compression applications. The core implements the ISO-14495-1/ITU-T.87 standard, which is based on the low complexity and highly efficient LOCO-I algorithm.

The JPEGLS-E delivers leading lossless compression efficiency on a highly efficient hardware architecture. A single instantiation of the core can encode 4K UHDTV or higher rates, and synthesizes to less than 60,000 gates. It is originally provided with FIFO-like pixel and stream input /output interfaces, but other standard interfaces (e.g. AMBA/AHB) are also available. Being carefully designed, rigorously verified, and production-proven, the JPEGLS-E is a reliable and easy-to-integrate core. Ease of integration is served by a complete verification environment, including a bit-accurate software model.

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 simulation and rigorous code coverage measurements. The core is silicon proven in FPGA technologies.


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