At www.opencores.org there is a ps2 interface in Verilog. If you grab
the System09 project there is a ps2 interface in VHDL.
You will need to add character decoding. Research the codes that are
transmitted for each key stroke. The are 'press' codes and 'release'
codes. Google will help... --- In fpga-cpu@fpga..., "cationebox" <cationebox@y...> wrote:

I have a keyboard controller posted at my website, but it's in verilog.
It's a basic raw controller that just returns scan codes as it
encounters them. It has the advantage that it uses a WISHBONE bus
interface.
