JPEG Decoder C Model
This a simple C model of a JPEG decoder that can decode baseline JPEG images. The purpose of this is to provide a reference to test the digital HW design against.
It supports;
- YCbCr 4:4:4 (no chroma subsampling), 4:2:0 and monochrome images.
- Conversion to a bitmap file (PPM / P6 format).
- Optimised (Huffman tables) images.
It does not support (currently);
- Progressive
- YCbCr 4:2:2 chroma subsampling
- Restart markers
- App data, COM sections, will be ignored.
