3 / 44 page ADV212 Rev. 0 | Page 3 of 44 The ADV212 can process images at a rate of 40 MSPS in reversible mode and at higher rates when used in irreversible mode. The ADV212 contains a dedicated wavelet transform engine, three entropy codecs, an on-board memory system, and an embedded reduced instruction set computer (RISC) processor that can provide a complete JPEG 2000 compression/decompression solution. The wavelet processor supports the 9/7 irreversible wavelet transform and the 5/3 wavelet transform in reversible and irreversible modes. The entropy codecs support all features in the JPEG 2000 Part 1 specification, except maximum shift region of interest (ROI). The ADV212 operates on a rectangular array of pixel samples called a tile. A tile can contain a complete image, up to the maximum supported size, or some portion of an image. The maximum horizontal tile size supported depends on the wavelet transform selected and the number of samples in the tile. Images larger than the ADV212’s maximum tile size can be broken into individual tiles and then sent sequentially to the chip while maintaining a single, fully compliant JPEG 2000 code stream for the entire image. JPEG 2000 FEATURE SUPPORT The ADV212 supports a broad set of features that are included in Part 1 of the JPEG 2000 standard (ISO/IEC 15444). See ADV212 User’s Guide for information on the JPEG 2000 features that the ADV212 currently supports. Depending on the particular application requirements, the ADV212 can provide varying levels of JPEG 2000 compression support. It can provide raw code block and attribute data output, which allows the host software to have complete control over the generation of the JPEG 2000 code stream and other aspects of the compression process such as bit-rate control. Otherwise, the ADV212 can create a complete, fully compliant JPEG 2000 code stream (J2C) and enhanced file formats such as JP2. |
