Vitis Codec Library

Vitis Codec Library is an open-sourced Vitis library written in C++ for accelerating image applications in a variety of use cases. It now covers a level of acceleration: the pre-defined kernel level (L2), and will evolve to offer the module level (L1).

Currently, this includes the following algorithm implementation:

• JPEG Decoder: “JPEG” stands for Joint Photographic Experts Group, the name of the committee that created the JPEG standard and also other still picture coding standards.
• PIK Encoder: PIK is the prototype of JPEG XL, which is a raster-graphics file format supporting both lossy and lossless compression. It is designed to outperform existing raster formats and thus to become their universal replacement.
