ps2 keyboard controller

Hi

I face some problem in decoding the scan code from the keyboard [ps/2]. I wrote some state machine to decode the scan code but it works fine for a moment and when i press the key quickly it cannot able to decode the scan code and once lost in fault the state machine is not able to decode the scan code further. i need to program it back again. Could any 1 tell me what could be the reason for this problem. I just cant figure out the actual problem..............

Thanks in advance
 

Why dont you check PS2-keyboard chapter in FPGA prototyping by verilog examples by Pong P chu. This book is available online. Search for this title in edaboard search.

Hope it helps.
