1. Add color mixing or dithering with more than 8 colors to the previous problem. The 3-bit color code in the RLE encoded memory can be used to map into a color palette. The color palette contains the RGB patterns used for color mixing or interlacing. On boards that support more than 8 colors directly in hardware, the color palette value can be used directly to drive several of the higher RGB output bits. The color palette memory selects 8 different colors. The program translating the bitmap should select the 8 closest colors for the color palette.
2. Modify the VGA Sync core to support a higher screen resolution and demonstrate it using one of the earlier example video designs.
