IP Module - Alma LJPEG-D

The LJPEG-D core implements a Lossless JPEG (LJPEG) decoder in a compact, high-performance, stand-alone package ideal for applications where bit-by-bit accurate repro-duction of an image is essential

The LJPEG-D decodes images that conform 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 can introduce round-off errors - the lossless part of the standard employs a reversible predictor function. The LJPEG-D core can thus decode images with no information loss, and requires a smaller physical implementation than what necessary for lossy JPEG image decoding
