2. ONE OF THE BASIC ATTARI GAMES. THE PONG GAME CONSISTS OF A BALL RANDOMLY BOUNCING ON THE SCREEN. A PADDLE AT THE BASE ENABLES THE USER TO MAKE THE BALL BOUNCE BACK UP. InTRODUCTION

3. MULTISYNC VGA MONITOR SUPPORTING 640X480 RESOLUTION. XILINX SPARTAN-3 FPGA KIT. TWO ONBOARD PUSH BUTTONS TO CONTROL PADDLE MOVEMENT. 50MHZ OSCILLATOR. requirements PUSH BUTTONS quadA, quadB vga_h_sync, vga_v_sync, vga_R, vga_G, vga_B

4. A VGA MONITOR REQUIRES 5 SIGNALS TO DISPLAY A PICTURE: R,G & B (THE RED, GREEN AND BLUE SIGNALS). HS & VS (THE HORIZONTAL AND VERTICAL SYNCRONIZATION). dRIVING The Vga monitor

5. GENERATING R,G & B SIGNALS. CLOCK DIVIDER. VIDEO GENERATOR DRAWING THE PADDLE DRAWING THE BALL MODULES USED

6. TWO ONBOARD PUSH BUTTONS FOR MOVING THE PADDLE LEFT OR RIGHT. 50HZ CLOCK REQUIRED FOR SCANNING THE PUSH BUTTONS. 6 CLOCK DIVIDER MODULES EACH DIVIDING THE CLOCK BY 10 (50MHZ/1000000HZ=50HZ). IF quadA IS PRESSED THEN PaddlePosition = PaddlePosition – 1; IF quadB IS PRESSED THEN PaddlePosition = PaddlePosition + 1; PaddlePosition = PaddlePosition +/- 25; FOR FASTER MOVEMENT. DRAWING THE PADDLE

7. 16X16 PIXELS SQUARE. RANDOM COLLISIONS. 4 “HOT SPOT” PIXEL, ONE IN THE MIDDLE OF EACH SIDE OF THE BALL. IF THE BALL DRAWS ITS “HOTSPOT” AT THE SAME TIME THE PADDLE OR BORDER DRAWS ITSELF, WE SAY THERE IS A COLLISION ON THAT SIDE. DRAWING THE BALL

8. THE ORIGINAL CODE USED NON PS/2 MOUSE FOR PADDLE MOVEMENT. CD4093 IC WASN’T AVAILABLE. THE PADDLE WAS UNCONTROLLABLE WHEN WE USED TWO PUSH BUTTONS AND 50MHZ CLOCK. RESTRICTED MOVEMENT OF PADDLE. pROBLEMS eNCOUNTERED The original setup used Pluto fpga board with 25MHz internal crystal and a modified mouse to control the paddle movement
