Design of VGA Controller IP Core Based on NIOS Ⅱ

In view of the problem that LCD controller IP core can only display number and letter,the paper proposed a design method of VGA controller IP core based on NIOS Ⅱ.It gave working principle of VGA,introduced design of VGA controller,and expounded design of VGA controller IP core,namely the designed VGA controller is installed to SOPC Builder.At last,the VGA controller IP core was added in NIOS II system to test its performance.The test result showed that the IP core can display many graphics,images and characters and can realize animation effect,which has a certain practical value.
