This demonstration displays a simple blue, red and green color pattern on a VGA monitor using the
VGA output interface on DE0_CV board.
Figure 5-11
shows the block diagram of the design. The
major block called video_sync_generator generates the VGA timing signals, horizontal
synchronization, vertical synchronization and blank in standard VGA resolution (640x480 pixels, at
25 MHz). These signals will be used in vga_controller block for RGB data generation and data
output. Please refer to the chapter 3.6 in DE0_CV_User_Manual on the DE0_CVSystem CD for
detailed information of using the VGA output. As shown in
Figure 5-12
,the RGB data drives each
pixel in turn across the row being displayed after the time period of back porch.
