DIGIC is Canon Inc.'s name for a family of SoC for digital cameras and camcorders. There is no publicly available specification for DIGIC chips. All information about DIGIC chip internals is based on reverse engineering efforts made by CHDK (http://chdk.wikia.com) and Magic Lantern (http://www.magiclantern.fm) projects contributors.
