Hi all,
I am at present working on interfacing a VGA Controller which was already ported for Cyclone II/Stratix II to Cyclone III(NEEK Board). Following is the link from where i downloaded the design. http://www.altera.com/support/refdesigns/sys-sol/computing/ref-niosii-vga.html?gsa_pos=3&wt.oss_r=1&wt.oss=vga Has anyone already worked on interfacing a VGA Core for Cyclone III? In the design example shown above in the link i'm not able to exactly picturize the functionality of vsync, hsync, sync and blank signals present in the vga_controller. May be vsync would do the Vertical Syncing and hsync would do the Horizontal Syncing but what is the use of sync(vsync xor ed with hsync) signal and blank signal. I'm also not sure of how to port these functionality in my top level design. Can anyone help me out? Please let me know if any additional information is required. Many thanks, Shyam Jude JLink Copied
