he objective is to build a general purpose microprocessor using the XCV300 FPGA board and Verilog. The 16 bit RISC will be created using MIPS design as a foundation. The processor will use state machine principles: fetch, decode, execute, read, and write to execute the instruction and data code. The processor will contain the following major components: controller, memory, instruction register, data registers, and an ALU. User interfaces will consist of Monitor/LCD and Keypad/keyboard.

We will create our own reduced instruction set and develop an assembler to convert the assembly code to machine language. The assembler will be written in C and executed on a PC. EPROM or EEPROM, and SRAM will be used to store the code necessary to test the microprocessor.

Test code could include a word game like scrabble, an output to a piece of hardware like a speaker or motor, or code that tests the performance of the processor design. For demonstration, a monitor could be used to display graphics that we design in our own assembly language or higher level mystery language.

Some possible design features include the following:

5 Stage Pipeline design
L1 Data Cache and Instruction Cache
Divider
Floating Point Unit
C Compiler

At the request of Colorado Space Grant, we are building a system that will act as the Power Distribution Control Unit for the Colorado Space Grant Consortium's satellite Citizen Explorer. The functionality of the PDCU has to meet specific given criteria, including:

Use the protocol of RS-422/485
The PIC will control the state of seventeen relays
The PIC will store to memory the state of each relay
The PIC will send the relay status and thermistor status to the flight controller at a set time or when otherwise requested by the flight computer
The flight controller will send commands as to the state of each relay and the PIC will determine whether the relay is in the correct state; if not the PIC will alter the state of the relay
The PIC will also receive information in the form of a digital signature, to ensure the flight controller is functioning properly; if functioning improperly, the PDCU will send a power pulse to restart the flight controller
The components will be placed on a PCB board and will be restricted to the dimension of 5"x 5"x 2"
Power system will be 80% efficient

Our group, Team Doki Doki, proposes to design a paintball gun auto-tracking/sensing system. It will feature a stripped-down paintball gun that is controlled via two stepper motors. One stepper motor rotates the gun left/right (most likely on a Lazy Susan) and a second stepper motor controls the up/down movement of the barrel. A linear actuator will be used to physically pull the gun's trigger. The stepper motors and actuator will be connected to the GPIO of a Xilinx Spartan 3 board. The board's FPGA will run a state machine with two main modes of operation: manual and automatic. When in manual mode, the left/right, up/down, and firing performance of the gun will be adjusted via an NES videogame controller connected to the serial port of the Spartan 3. This mode will be implemented first, as it will be the more straightforward of the two. The NES controller will also be used to switch the state machine between auto/manual modes. When switched into automatic control, the gun will either scan for or track a certain type of target. This target may be a certain color, if we end up implementing video capture and analysis into the board, or it may be using IR, which would require the target to be wearing an IR sensor. Perhaps there is even another method? Currently, we are not sure what will be most feasible while still yielding some practical application.

This auto-tracking gun could have two potentially marketable uses. First, it could be used rather directly as a "sentry gun" in paintball arenas. It would scan for human players, potentially only those from a certain team, and create an additional hazard they must avoid. This would create another interesting aspect to the popular game of paintball. Second, it could be used as a home security device. The gun could placed in front of a door or window and automatically perform non-lethal attacks to scare away intruders while the homeowner sleeps or is out. Such an implementation could be especially useful for those with hearing and/or vision problems, as they may have trouble detecting the intruder on their own. Note that both of these uses would be more practical if the auto-sensing/tracking mode of the gun were based on thermal detection, although this form of targeting is not fiscally reasonable for our prototype.

We have a goal of building a car which will have the capability of being controlled wirelessly. This car will have a number of sensors on it that will send back data. Possible sensors may be: temperature, sound, light, video, GPS, ect... This data will be sent back to the source wirelessly via either RF, 8011B, or serial cable. The car could be controlled by a website upon further analysis. The data can also be stored in on on board flash card. As we move along in our project, we are leaving ourselves open to any other anmenities that we might be able to add on.

To design and build a small box that integrates a digital signal processor to add audio effects to a guitar input or other analog source. When the user uses a guitar input, he/she can use buttons and LCD to select various guitar effects, which will then be applied to the (digitally converted) audio signal and passed out through the analog output. As with most guitar effects pedals, this unit will use a 9VDC source, available through either a battery or a 9V DC adapter.

Our project is primarily a security device that allows a client to be authenticated remotely (approx. 20-30 yards away) and given access to a facility, entry to a building, control of lights or other devices, etc. Secondly it is a Biometric information transmitter that could be used to transmit patents bio-signs to a nursing station, a doctor's PDA or other electronic device.

We will create two devices: the primary device that is responsible for authentication and communication and the secondary device that controls the light, garage door, etc., and receives data collected by the primary device.

Fingerprint authentication using FPGA in primary device.
Communication with secondary device using radio signal/Bluetooth/Wi-Fi
- Activates light, door, etc.
- Send data (Pulse, oxygen level, blood pressure, etc)
Verify that user of authenticator is living using a pulse oximeter to measure oxygen levels in blood and pulse rate.
Secondary device is able to cut and supply power to device being controlled.
Secondary device send basic signal to controlled device.
Create a user interface for operating the primary device.
- Add/Remove fingerprint
- List of devices functionalities
- Add/Remove controlled devices
Create interfaces for other devices, garage door, elevator, computer access, etc.
Connect other data gathering devices to primary device so that one can monitor environment remotely (for example, a hospital patient).

Feasibility: due to the high complexity of the project as well as the limitation of members in the group, we think the primary device can be completed with a LCD user interface. For the secondary device, if we don't have enough time, activates light module will be chosen for the purpose of the course.

A common problem among motorcycle riders is communicating with fellow motorcyclists while riding. This communication typically presents great risks to the rider, as well as other motorists on the road due to the fact that the motorcyclist may be tempted to remove a hand from the handlebars to make a gesture or even worse turn their head to look at a trailing rider. Communications may take the form of giving directions, warning against hazards on the road, or simply socializing with fellow riders.

There are several parties affected by this problem. First and foremost, the motorcycle rider is the primary interest. Rather than shouting over the wind, traffic, and engine noise to your fellow rider and using random hand signals, this device will allow for simple and effective communication between motorcyclists. A second group of stakeholders are the other motorists on the road. This device will allow the riders to maintain concentration on the road at all times, thus increasing the safety of other motorists.

We propose to build a digital control device for the Physics department that will be used to augment their laser cooling systems. The lasers they use are locked to a specific electronic transition of a rubidium atom and are used to cool rubidium atoms to temperatures in the micro kelvins (near absolute zero). As with all lasers, over time, they tend to drift in wavelength. Analog feedback exists to keep the laser locked at this wavelength. The laser can stay locked for very long periods of time, but perturbations such as bumping the table or rapid temperature changes can break the lock. An operator is then needed to make the delicate changes to the system to re-lock the laser. Our digital control device will do all of the work in locking and re-locking the laser and make it so all a human has to do is push a button. In order to accomplish this project, we are going to want this digital control device in a box that is 2U rack mountable. We plan to display things similar to an oscilloscope on a screen and have either a keypad or dial for user inputs. The main input from the existing analog system is produced by saturated absorption spectroscopy and gives information about the wavelength of the laser in relation to a sample of the reference material. We also plan to mount an I/O connection on the box to interface with a computer workstation, and an I/O connection to the analog control to exchange commands and status. Our main goal is to get this box to operate on its own, without help from another external computer. We then intend to give the Physics department the option of having this device controlled by an in-lab computer via an I/O port, giving our device, and the entire laser cooling system, a more automated feel.

We propose to design an infrared tracking and solar supply system for use with a digital camcorder. It will feature a pan/tilt mounting system for tracking purposes and a small solar array to power all devices. Within the mounting system, one stepper motor adjusts the pan (left/right) movement while the second stepper motor adjusts the tilt (up/down) movement. The stepper motors will be controlled via the Xilinx Spartan 3 board. A finite state machine will be implemented to provide both automatic and manual control. The automatic control will be governed by an array of pyro-electric infrared sensors. Infrared radiation will be focused through a Fresnel lens at each sensor to increase the received radiation. A set of converters will be integrated into the solar power system to provide necessary voltages to power various loads and system components. A separate lead acid battery for the additional components and possibly the existing lithium ion battery will be recharged by the solar system allowing for night usage. For night filming, a high intensity LED cluster will be incorporated into the design. Possible additions to the project include: a solar tracking system to position solar panels for maximum power, a real time data acquisition link, video processing of acquired data, and a wireless manual control unit. There are several marketable applications for the system including home security, proximity alert, and live action filming.
