2 VIC Description
Video Interface Controller
2.1 Data Input Formats
Video Interface Controller supports different color formats displayed in figure 2-1 but does not convert
color format into each other. Color depth for video target layers has to match color depth of incoming video
data. Color conversion and mapping to display color depth will be done in output stage within GPU.
The Video Interface Controller has two data ports (port A and B), each 8 bit wide. In single port mode only
port A will be used. Double port mode means that data will be received on both ports (A and B, 16 bit).
Additionally VIC supports two different clock modes. Single clock mode uses only one clock phase (edge)
while double clock mode uses both phases. In double clock mode, data on port A changes with every edge
of clock. Port B (if enabled) and control signal only works in single clock mode. Different color modes de-
pending on clock mode are shown in figure 2-1.
