hello community, can anybody show me a tutorial about creating custom IP core, I am using de2-115 boards, Regards

hi vicky

my next concern is that I am sending image to the vga monitor but the quality of the displayed image in VGA is bad,

I am using :

alt_up_video_dma_dev* video;

video=alt_up_video_dma_dev("/dev/VGA_Subsystem_VGA_Pixel_DMA");

read RGB image from memory then putting them into img1,img2,img3 respectively .

loop:

alt_up_video_dma_draw(video,img1[i][j]*65536+img2[i][j]*255+img3[i][j]*65536,i,j,1):

end loop

any clue?
