IntroductionIntroduction

Purpose Prototype an arcade style game station capable of running a video

game Provide audio-video output (video via Composite Video) Accept user input via button presses Program Pong as the demonstrable video game for the game

station

Goals To meet all Engineering Development Milestones. To maximize ROI by minimizing development and production costs. To deliver a working prototype with accompanying documentation

by December 4.

SoftwareSoftware

A completely recreated game of pong with sound, as well as multiplayer support

Composite Video Driver, capable of converting mapped pixels in memory into a TV image

Sound Driver, capable of playing a sound file in memory

Board ImplementationBoard Implementation

Wire-wrap capable due to relatively slow CPU (10Mhz)

Board contains processor, memory, inputs, and outputs

Located inside of casing

Hardware ImplementationHardware Implementation

Motorola MC68000 Processor Necessary for large addressable memory space http://e-www.motorola.com/files/32bit/doc/ref_manual/EC000UM.pdf

4MB DRAM Executable approximately 500Kb in size Sound and video storage approximately 1700Kb in size 1800Kb Contingency

Xilinx FPGA Memory mapped I/O Video/Sound driver Easy to implement on FPGA

10Mhz Clock Slow speed necessary to avoid wire-wrap problems

Interrupt Controller Motorola 8214 Programmable Interrupt Controller

Reset Switch Necessary to ensure all board components are initialized together

Serial Port Transfers code from PC to the game station

Software ImplementationSoftware Implementation

Written using MC68000’s C compiler Easy to program Powerful games easily realized

Audio/Video Storage Bit array representing black or white pixels. Audio shall be stored in custom format.

Intermediate DeadlinesIntermediate Deadlines

CDR Design, test, and implement prototype board Successfully run code on prototype board

Milestone 1 Complete development of individual modules Get board to interface with video display device

Milestone 2 Integrate modules Run test executable to demonstrate working hardware

Final GoalsFinal Goals

Expo Implement Pong as final demonstration of

functional game station. User can interface with device to change the

screen output Basic scoring and game rules implemented Sound output reflective of gameplay

Parts List with Cost EstimatesParts List with Cost Estimates

Because of mass purchasing, price will be effectively decreased to one-quarter of prototype cost

Components will be optimized once a prototype is built

Per unit cost will be approximately $15.00 Retail unit cost will be $20.00 for a 33% net

profit on investment
