The byte router function provides additional flexibility to the TVP3030. As shown in Figure 1–1, the byte
router receives data from two sources. From the true-color multiplexing logic, the byte router receives the
red, green, and blue bytes of direct-color data. This data is in the same format as when it is applied to the
DACs in direct-color mode. From the page register, the byte router receives the 8-bit pseudo-color data. The
source of the pseudo-color data can be from the VGA port, from the pixel port in a pseudo-color mode, or
from the overlay fields in a direct-color mode with overlay.
Byte Router
The byte router can be programmed to route each of the four input bytes to any of the four output bytes as
described in the register description in the following section. An example application of the byte router would
be a system which supports both 24-bit true-color and 8-bit monochrome image formats using the same
memory port. For the 24-bit true color mode, true color gamma correction could be used and the byte router
would pass all inputs straight through. For this, the byte router control register is set to its default of 0xE4.
For the monochrome image mode, the 8-bit image data could be received through the blue pixel bus input
channels. True-color gamma correction would again be used and the byte router would route the blue input
byte to the red, green, and blue output channels. The pseudo-color data would pass straight through the
byte router but would not be selected by the palette RAM. For this, the byte router control register is set to
0xFC.
