Problem in building a LCD panel controller in SOPC

question 3:

I download nios_lcd_3c120 design example from Altera,but it didn’t use frame buffer block of video and image processing, does frame buffer block is a new block of quartus II 9.0? is it necessary to use this block to build buffer in external memory ? (nios_lcd_3c120 doesn’tuse)

And how to use it?

Reply: Hi,

I am using nios_lcd_3c120 desing to use LCD controller on 3c120 board. Yes it does not need the frame buffer block of VIP suite. Instead it uses DDR2 SD RAM as buffer memory which you can use as a heap/stack/program memory.

Why do you want to use frame buffer?
