This JPEG-Decoder IP has been optimally designed for easy integration into any FPGA: the footprint is very small, thecode is portable to any vendor, and the performance (Fmax, Throughput, and Image Quality) is high.It can decode Still Images and Video Streams (Full HD, 4K). The JPEG-Decoder comes with Block to Raster Converter integrated.It is a perfect companion for the ALSE JPEG-Encoder for creating a complete compressed video transmission chain.A sophisticated HDL simulation environment is available to facilitate the integration of the IP in the customer project.


  • Baseline JPEG-Decoder with support of any image resolution up to 64K x 64K. 4:2:0/4:2:2 Support
  • Standard Huffman Table / Quantization tables dynamically extracted from JPEG stream
  • Streaming mode (Full HD / 4K support) or Still Image
  • Very compact and highly optimised in Speed
  • Easy Integration (no need of external RAM, block-to-raster blocks provided)

Device Utilization and Performance

Decoder alone is ~3700 LEs or 1500 ALMs, 5 Memory Blocks, 9 multipliers.Fmax > 180MHz on low-cost Cyclone® IV-CV.
