The Alma Technologies LJPEG-E IP Core implements the Lossless JPEG compression in a very compact, high-performance and stand-alone package. It supports up to 16-bit per component Numerically Lossless encoding and is ideal for image and video compression applications where bit-by-bit accurate reproduction of an image is essential, while the amount of compression needed is very low.
The LJPEG-E conforms to the spatial (sequential) lossless encoding mode (SOF3) of the ISO/IEC 10918-1 standard (CCITT T.81 recommendation). Rather than the Discrete Cosine Transform (DCT) functions used for lossy JPEG compression - which introduce round-off errors - Lossless JPEG employs a predictor function and compresses images by encoding the prediction error with no information loss.
The LJPEG-E core is designed with simple, fully flow-controllable and FIFO-like, streaming input and output interfaces. Being carefully designed, rigorously verified and silicon-proven, the LJPEG-E is a compact, reliable and easy-to-use and integrate IP.
