ADV212
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.
