Color Data Format Conversion
• ∆
YUV/YUV-to-RGB conversion
The specifications of the function for converting
∆
YUV or YUV data in main memory to RGB
data are shown in figure 3-12.
The Q2 converts
∆
YUV or YUV data transferred from the CPU to RGB data and stores it in the
UGM source area. The converted RGB data is used as source data for quadrilateral-drawing
commands.
Q2 registers that should be set by the CPU are as follows. Make the register settings in the
order shown in figure 3-13.
