  De-Interlacing and YUV 4:2:2 to 4:2:0 Conversion on DM6446 Using the Resizer (Rev. B)
  PDF, 186 Kb, Revisión: B, Archivo publicado: dic 17, 2008
  Video signals captured directly from charge-coupled device (CCD) cameras naturally have interlaced effects and are in a 4:2:2 interleaved format. They typically need to be converted to a 4:2:0 planar format before being encoded because most video compression standards accept input only in 4:2:0 format. It is better to reduce or remove the interlaced artifacts in the original video signal when fe

  Booting DaVinci EVM from NAND Flash (Rev. A)
  PDF, 3.4 Mb, Revisión: A, Archivo publicado: dic 15, 2008
  Currently, the DaVinciв„ў evaluation module (DVEVM) supports three boot modes: the DVEVM can boot from NOR (default), NAND, or universal asynchronous receiver/transmitter (UART). NOR Flash offers the advantages of one-byte random access and execute-in-place technology. NAND Flash is not as easy to work with since it requires Flash Translation Layer (FTL) software to make it accessible; however
