JPEG-EX-S Baseline and Extended JPEG Encoder

This JPEG compression IP core supports the Baseline Sequential DCT and Extended Sequential DCT modes of the ISO/IEC 10918-1 standard. It implements an area-efficient, high-performance, ASIC or FPGA hardware JPEG encoder with very low processing latency.

The JPEG-EX-S Encoder produces compressed JPEG images and the video payload for Motion JPEG container formats. It accepts images with 8- or 12-bit color samples and up to four color components, in all widely-used color subsampling formats.

The encoder processes one color sample per clock cycle, enabling it to compress multiple Full-HD channels even in low-cost FPGAs. One of the smallest JPEG encoders available, it requires just 80,000 equivalent gates when mapped on an ASIC technology.

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-S core’s low processing latency and ability to regulate compressed image size or video bit rate make it ideal for video streaming systems even in the presence of strict bandwidth and latency limitations. Suitable applications include:

Silicon Resources Utilization

The JPEG-EX-S Encoder core synthesizes to approximately 80K gates and requires 16k to 30k-bits of memory, depend-ing on tis configuration.


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:
