PS/2 in DE1

Hi,

I'm a beginner of Quartus II and SOPC builder. I'm building a dot matrix display using DE1 board and I was required to key in the word I like to display via keyboard. I had wrote the VHDL code to build a PS/2 core but I don't know how to implement it with SOPC builder, since I need to store some commands to control the output.

I found a program from Altera University Pogram but I don't know how to implemet it.

Is there any suggestions of using the PS/2 port most effeciency for my case?
