7.4 MEMORY STORING METHOD
The storing method to the frame memory is the little-endian method. The first entering pixels stored into LSB
sides, and the last entering pixels stored into MSB sides. The carried data by AXI bus is 64-bit. Therefore, CAMIF
make the each Y-Cb-Cr words by little endian style. Refer to Figure 9.3-11.
