CycloneV ddr2 hw uniphy ip, does the four PORT is to decrease the MM IF frequency?
Hi,now I am working with the CycloneV DDR2 hw uniphy ip core, DDR2 270MHz,16bit,BL=4.
4 PORT Type = read,Width=32,priority =7,5,3,1,weight=0, different ddr bank. Interface MM 59MHz,BL=32. Four ports could read 960 data within the 64us, 960*4/64us=60MHz,this result is only Equivalent to a port，why? How to set the PORT Type-Width-Priority-Weight and ddr bank to work Optimaly? http://www.alteraforum.com/forum/attachment.php?attachmentid=10102&stc=1
