Description
The JPEG IP core is intended for high-speed decoding of gray-scale images coded with ISO/IEC 10918-1 baseline coding standard. The decoder supports all features of the baseline standard, including restart markers and full header parsing. It is able to decode abbreviated-format or full-format images, automatically extracting the quantization and entropy tables.

With its autonomous behavior, simple FIFO-like interfaces, and 100% synchronous structure, you can integrate this IP core in a complex system with little effort. This is reinforced by the stand-alone ability of the decoder that allows you to instantiate it in systems without CPU intervention."
