That megacore or altsyncram I would recommend. If you type either of those names into the Quartus II help you will get a data sheet for the lpm function.

My question for you is will this DP ram be used in SOPC Builder? If so, you can drop an onchip memory into your system and use it in dual port mode in the memory configuration wizard (check box near the top). One word of caution is to make sure you don't do parallel access to DP Ram at the same address (you probably already know that, just making sure).
