JPEG-EX-S: Baseline and Extended JPEG Encoder
The JPEG-EX-S IP core supports Baseline and Extended Sequential DCT modes of ISO/IEC 10918-1, implementing a high-performance, area-efficient HW JPEG encoder for ASIC or FPGA with low latency. It produces compressed JPEG images and Motion-JPEG payloads, handling 8- or 12-bit samples and up to four components in all common subsampling formats. Processing one sample per cycle, it can compress multiple Full-HD channels even in low-cost FPGAs. One of the smallest encoders, it uses ~80k gates in ASICs. Once programmed, it operates standalone without host assistance. Integration is simple via AMBA®: AXI Streaming for pixels/data and 32-bit APB for registers, with optional AXI Streaming for timestamps or metadata. CAST offers IP Integration Services delivering complete JPEG subsystems with decoders, video interfaces, UDP/IP or Transport Stream stacks, or other IP. Designed to industry best practices, reliability is proven by verification, production use, and a bit-accurate software model.
