D e scription of th e work assign ed

In the project proposal has been presented before, the group hasset out the non-functional requirements and functions needed for Pong game. Also build a general block diagram for the system,including :

- External control bolck : Keyboard PS /2

- Display block : VGA M onitor

- Audio processing block : IC WM8731

- Main game block.

This report focus describes the system design details. Summarythe structure and relationships between the blocks above.

kb_main: This is no RTL in this block. It simply ties together the keyboard_scanand keyboard_convert blocks.

keyboard_scan: This block interfaces directly with the data and clock pins on the PS /2 keyboard. It can detect any key on the keyboard pressed or depressed

and sends scan_code bits to keyboard_convert .

keyboard_convert: This block controls the keyboard_scan block, reads the keyboard codes (scan_code) and converts keyboard codes to ASCII codes (hex, ascii) which can appear in the seven-segment LED display, VGA display or controls any function (i.e. up, down, left, right) .

V GA _Controller: This block interfaces directly with the hsync, vsync, red, green, blue video output signal on the DE 1 board. This block should allow for displaying the following on the VGA monitor :

-Shape, size and colour of the playground, paddle and ball

-The movement of the paddle_ 1, paddle_ 2 and ball based on the parameters from the paddle_ 1, paddle_ 2 and ball block.

-Position of the barrages which appear when level up. It based on the parameters from the Pong_main block.

-Scores for each player, which will be from 0 to 15 only.

SD_interface: This block interfaces directly with SD Card.

Au dio_controller: This block interfaces directly with WM8731 .

Paddle_ 1, paddle_ 2 : Simple counter which increases /decreases the paddle value if the up /down is asserted. In other words, the paddle moves only in one direction and based on user input from the keyboard.

Pong_main: This is the main backbone to the game and is thus a little more complex. With the given specifications, this block should make following :

-Synchronization behavior of kb_main, paddle_ 1, paddle_ 2, ball,

VGA _controller, Audio_controller and SD_interface block. (i.e. at a time, those action has occurred; controlling the postion of paddle by using parameters from kb_main)

-Providing the parameter for movement of the ball.

-Receiving audio data from SD card and sending it to IC WM8731 .

-Counting the scores and show the winner. The score should be provided for the display on the VGA monitor.
