JPEG-D-S: Baseline JPEG Decoder
The JPEG-D-S IP core is a compact, high-performance hardware JPEG decoder supporting the Baseline Sequential DCT mode of ISO/IEC 10918-1. It decompresses JPEG images and Motion-JPEG payloads, handling 8-bit samples and up to 4 components in all common subsampling formats. Processing 1 sample/cycle, it can decode multiple Full-HD channels even in cost-sensitive FPGAs. One of the smallest decoders, it uses about 4,000 ALMs in Altera FPGAs. Once programmed, it operates standalone, parsing markers and decompressing without host intervention. It reports resolution, subsampling, and depth for proper post-processing or display. Integration is simple via AMBA®: AXI Streaming for pixels/data and a 32-bit APB slave for registers. CAST offers integration services delivering complete JPEG subsystems with decoders, video interfaces, networking stacks, or other IP. Designed with best practices, its proven reliability is backed by verification, production use, and a bit-accurate software model.

JPEG-DX-F: Ultra-Fast Baseline and Extended JPEG Decoder
This JPEG decompression IP core supports the Baseline & Extended Sequential DCT modes of the ISO/IEC 10918-1. It is scalable and ultra-high-performance, while handles extremely high pixel rates of JPEG images and video payload for Motion-JPEG container formats. It accepts compressed streams of images with 8- or 12-bit color samples and up to four color components, in all widely-used color subsampling formats. It can process from 2 to 32 color samples per clock cycle. Paired with the JPEG-EX-F Encoder Core provide an extremely cost-effective solution. Standalone operation, once programmed, parsing marker segments, decompressing coded data and reporting back the image format. SoC integration is straightforward (standard AMBA I/F - AXI Streaming & APB Slave). CAST’s IP Integration Services are also available for JPEG subsystems (the JPEG decoder with video interface controllers, Hardware UDPIP or Transport Stream networking stacks, or other IP cores available from CAST).

JPEG-EX-F: Ultra-Fast Baseline and Extended JPEG Encoder
This JPEG compression IP core supports the Baseline and Extended Sequential DCT of ISO/IEC 10918-1 standard. It is scalable and ultra-high-performance, while handles extremely high pixel rates using significantly fewer silicon resources and less power than encoders for video compression standards such as HEVC/H,265, DSC, AVC/H.264, or JPEG200. The JPEG-EX-F encoder accepts images with up to 12-bit color samples and up to four color components, in all widely-used color subsampling formats. It can process from 2 to 32 color samples per clock cycle enabling it to compress UHD (4K/8K) video and/or very high frame video. Standalone operation, once programmed, with straightforward SoC integration (standard AMBA I/F - AXI Streaming & APB Slave). CAST’s IP Integration Services are also available for JPEG subsystems (the JPEG decoder with video interface controllers, Hardware UDPIP or Transport Stream networking stacks, or other IP cores available from CAST).
