This JPEG-D-S core is a high-performance JPEG decoder supporting the Baseline Sequential DCT mode of the ISO/IEC 10918-1 standard. It is suitable for decompressing JPEG images and the video payload of Motion-JPEG container formats..The core decodes one color sample per clock cycle, and is able to process Full-HD 1080p video in most FPGA devices. Once programmed, the easy-to-use decoder operates on a standalone basis, parsing marker segments and decompressing coded data with no assistance from a host processor. SoC integration is straightforward thanks to standardized AMBA' interfaces: AXI Streaming for pixel and decompressed data, and a 32-bit APB slave interface for registers access.


  • Standards: ISO/IEC 10918-1 Baseline Sequential DCT mode
  • Throughput: 1 cycle per sample.
  • Image format: 8bit per color, up to 4 color-components in all widely used subsampling format, and resolution up to 64kx64k
  • Standalone operation requires no assistance from host processor.
  • Optional Block-to-Raster Conversion with AXI or standard memory interface towards the lines buffer

Device Utilization and Performance

The JPEG-X-S core can be mapped to any Intel® FPGA Device (provided sufficient silicon resources are available) and optimized to suit the particular project's requirements. The core occupies approximately 4,000 ALMs, 5 DSPs and 32Kbits of memory, and can process 1080p60 on Intel Arria® 10 or Stratix® V devices, or 720p60 in Max 10 devices. Please contact CAST to discuss resource utilization and performance for your application and target device.
