The JPEG-LS-E core implements a highly-efficient, low-power, lossless and near-lossless image compression engine that is compliant to the JPEG-LS, ISO/IEC 14495-1 standard. Based on LOCO-I (LOw COmplexity LOssless COmpression for Images), the JPEG-LS algorithm leads in numerically lossless compression efficiency, attaining compression ratios similar or superior to those obtained with more advanced algorithms such as JPEG2000. JPEG-LS also enables hardware implementations with a much smaller silicon footprint and lower memory requirements, thanks to its lower computational complexity and line-based processing.

Features and Benefits
- Highly Efficient Numerically Lossless Compression
- Better compression ratio than most lossless compression algorithms (JPEG2000, PNG, etc.)
- Near-Lossless Compression :
- Enables greater compression with visually lossless quality by constraining the maximum difference between reconstructed and original image samples
- Maximum image resolution of 64Kx64K, or higher via support for oversize image dimension parameters
- Up to 16 bits per color sample; up to four color components
- Ease of Integration :
- AXI4-Stream interfaces for image and compressed data, and 32-bit wide APB for register access
- Throughput :
- Area-optimized JPEG-LS-ES: one sample per cycle
- 40,000 eq. gates and up to 500 Msamples/sec on a typical 28nm technology
