Bayer data, ASP, CFA, ITU-R BT.656 , edge enhance, chroma suppression , CLUT Audio Serial Port (ASP) The primary use for the audio serial port (ASP) is for audio interface purposes. A Bayer filter mosaic is a color filter array (CFA) for arranging RGB color filters on a square grid of photosensors. he filter pattern is 50% green, 25% red and 25% blue, hence is also called RGBG,[1][2] GRGB,[3] or RGGB.[4] http://en.wikipedia.org/wiki/Bayer_filter ITU-R BT.656 standard for.. 2013. 3. 26.
OneNAND TCM Tightly-coupled memory OneNAND The OneNAND is a highly reliable embedded memory targeted for both consumer electronic, and next generation mobile phone market. With accumulated NAND flash technologies over the last decade, the company designs an ideal single memory chip based on NAND architecture integrating SRAM buffers and logic interface.
