multiplexer (MUX) which is controlled by the VGA controller to perform the de-interlacing
operation. Internally, the VGA Controller generates data request and odd/even selection signals to
the SDRAM Frame Buffer and filed selection multiplexer (MUX). The YUV422 to YUV444 block
converts the selected YcrCb 4:2:2 (YUV 4:2:2) video data to the YcrCb 4:4:4 (YUV 4:4:4) video
data format.
Finally, the YcrCb_to_RGB block converts the YcrCb data into RGB data output. The VGA
Controller block generates standard VGA synchronous signals VGA_HS and VGA_VS to enable
the display on a VGA monitor.
