Developing A Tetris Game in Parallel Format

The concept of making this project is to create a parallel Tetris game where each player can play the game using the PS/2 keyboard for input in his own screen while simultaneously influencing the play of the opponent.

The display is one of the most important aspects of the project in the design of the game. Modifying the display based on the needs of the game requires good understanding of the VGA controller. There are two 10 bits outputs which are coordinate X and coordinate Y in the VGA controller. Two Altera DE2 board was used which communicate to each other over the serial port. This is responsible for moving up the opponent to a predefined number of lines when a player cleared lines on his game. Also, each player can view the state of the opponent’s game on his own screen.

The PS/2 keyboard was the next important component in the design which uses a verilog module for identifying the scan codes of the keys. The RS232 serial port on the DE2 board was used since it was fast enough to handle the amount of data transfer with serial communication.
