JPEGLS-E

JPEG-LS Encoder

UHT-JPEGLS-E

Ultra-High Throughput JPEG-LS Encoder

JPEG-LS IP

The JPEG-LS compression scheme was developed to provide a low-complexity lossless image compression standard. The corresponding ISO-14495-1/ITU-T.87 standard is based on the LOCO-I algorithm (LOw COmplexity LOssless COmpression for Images) developed at Hewlett-Packard Laboratories. JPEG-LS offers the JPEG 2000 lossless compression efficiency advantage in a much more compact silicon footprint and without requiring an external memory device for the implementation.

The JPEG-LS encoder IP core from Alma Technologies supports up to 16-bit per component numerically lossless encoding, includes the run-length coding mode and offers high encoding throughput even in low-end FPGA or ASIC silicon.

The JPEGLS-E core is also available in a configuration that includes support for the JPEG-LS NEAR-Lossless encoding mode. The NEAR-Lossless configuration offers higher compression, at user defined maximum allowed reconstructed data error, but runs much slower due to a different data-path architecture which has to include feedback loops that cannot be pipelined while maintaining the single clock cycle per input sample processing rate.
