Yeah sure.
First of all which version of the core are you using?
There's an old (simple_i2c) and the i2c_master core.
Use the latter; map it into the DSP's memory range and access it as though
it's a memory device.
Read the documentation for the register addresses.

Hi

Can anyone please help me?  I need to implement an i2c bus for a project.  I
am using a dsp to send commands to registers in an fpga from where I will
control the i2c.  I am using an existing reference design for my development
board.  Can anyone please help me with something?  I got the documentation
for the i2c master core written by R. Herveille.  I know that I need to
write to registers to read and write, but I don't know how to access those
registers using the reference design.  In other words, I just need to know
if anyone can help me to integrate the i2c controller using the reference
design?

Thank you.
