JPEG-DX-S: Baseline and Extended JPEG Decoder
The JPEG-DX-S IP core is an area-efficient high-performance JPEG decoder supporting Baseline and Extended Sequential DCT modes of ISO/IEC 10918-1. It decodes JPEG and Motion-JPEG payloads, supporting 8- or 12-bit samples and up to four components in standard subsampling formats. Processing one sample per cycle, it can handle multiple Full-HD channels in cost-sensitive FPGAs. One of the smallest available, it requires ~76k gates in ASICs. Once configured, the core runs standalone, parsing markers and decompressing without host intervention. It reports resolution, subsampling, and depth for correct post-processing. Integration is simple via AMBA®: AXI-Stream for pixels/data and a 32-bit APB for registers. CAST offers integration services delivering complete JPEG subsystems (decoders, video interfaces, networking stacks, etc.). Designed to industry best practices, quality is proven by verification, silicon validation, and a bit-accurate software model. Scan-ready, LINT-clean, production.
