  • Scalable Ultra-High Throughput JPEG-LS Encoder
    • The UHT-JPEGLS-E core is a JPEG-LS encoder, compliant to ISO/IEC IS 14495-1 | ITU-T Recommendation T.87 standards.
    • It supports encoding of 4:4:4, 4:2:2, 4:2:0 and 4:0:0 (grayscale) video streams, in 8 up to 16 bits sample depths.
    • The core is a standalone and high-performance JPEG-LS encoder, designed for enabling ultra-high frame rate SD and HD encoding, and Ultra HD video encoding (4K/8K and beyond), even in low-end ASIC or FPGA silicon.

  • Lossless & Near-Lossless JPEG-LS Encoder
    • 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 JPEG 2000.

  • Lossless & Near-Lossless JPEG-LS Decoder
    • The JPEG-LS-D core implements a highly efficient and low-power, lossless and near-lossless image decompression engine that is compliant to the JPEG-LS, ISO/IEC 14495-1 standard.
    • The decoder core can decompress any JPEG-LS stream or JPEG-LS payload of image container formats, such as DICOM (Digital Imaging and Communications in Medicine).

  • JPEG-LS Lossless Image Encoder
    • Leading lossless image compression results for 8 to 16 bits image sample depths
    • Less than one line of encoding latency
    • Low resource count, no external memory needed. Scales to multiple instances is easy
    • Pixel and data FIFO input/output or Avalon Streaming interface with back-pressure
