JPEG is the image compression standard developed by the Joint Photographic Experts Group. It works best on natural images (scenes).
The JPEG decoder has been highly optimized to run on the Analog Devices' Blackfin® processor family. It is a self-contained software module that is fully compliant with ISO/IEC 10918-1:1993 (ITU-T T.81). This software has undergone rigorous interoperability testing across many commercially available platforms, and open source applications. This module can be used to build a Motion-JPEG video system, for example using the AVI file format.
The module uses a C-callable API that includes a number of system interface hooks via user call-back functions. This allows better customization and optimization of data input/output integration, and meta-data processing (for example EXIF). The code has no dependencies on processor peripherals or registers, adding greater system flexibility and ease of use.
