JPEG-EX-F Ultra-Fast, 4K/8K, Baseline and Extended JPEG Encoder

This JPEG compression IP core supports the Baseline Sequential DCT and the Extended Sequential DCT modes of the ISO/IEC 10918-1 standard. It implements a scalable, ultra-high-performance, ASIC or FPGA, hardware JPEG encoder that can compress high pixel rate video 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 produces compressed JPEG images and the video payload for Motion-JPEG container formats. It accepts images with up to 12-bit color samples and up to four color components, in all widely-used color subsampling formats.

Depending on its configuration, the encoder processes from two to 32 color samples per clock cycle, enabling it to compress UHD (4K/8K) video and/or very high frame video.

Once programmed, the easy-to-use encoder requires no assistance from a host processor to compress an arbitrary number of frames. SoC integration is straightforward thanks to standardized AMBA® interfaces: AXI Streaming for pixel and compressed data, and a 32-bit APB slave interface for registers access. Users can optionally insert timestamps or other metadata in the compressed stream using a dedicated AXI Streaming interface.

Customers with a short time to market priority can use CAST’s IP Integration Services to receive complete JPEG subsystems. These integrate the JPEG encoder with video interface controllers, Hardware UDPIP or Transport Stream networking stacks, or other IP cores available from CAST.

The core is designed with industry best practices, and its reliability and low risk have been proven through both rigorous verification and customer production. Its deliverables include a complete verification environment and a bit-accurate software model.

The JPEG-EX-F core is suitable for systems supporting ultra-high frame resolutions and/or frame rates, such as:

Silicon Resources Utilization

The silicon resources requirements for the JPEG-EX-F encoder core depend on its configuration. The default two samples per cycle configuration synthesizes to approximately 120K gates and requires 50k bits of memory.


The core has been verified through extensive synthesis, place and route and simulation runs. It has also been embedded in several products, and is proven in both ASIC and FPGA technologies.


The core as delivered is warranted against defects for ninety days from purchase. Thirty days of phone and email technical support are included, starting with the first interaction. Additional maintenance and support options are available.



The core is available in ASIC (synthesizable HDL) and FPGA (netlist) forms, and includes everything required for successful implementation:
