I am looking for an example of how to instantiate Xilinx dual-ported block RAM in the Impulse environment. I want to be able to write to one port with one hardware process and read the other port with another hardware process. Thanks.

This question has been answered in support emails. Here is an excerpt from the email thread:

A global array may be created and accessed from two separate processes, each getting a separate port on the dual-port RAM created during synthesis. The multiple processes accessing a global array are then subject to the general rule that exists within all Xilinx PSP’s regarding dual-port RAM access in that one port may read and write while the other port may only read. A global array by default (co_array_config() does not currently affect global arrays) will be implemented as a dual-port synchronous RAM with the final decision on whether it is created in distributed or block RAM being made by XST.
