This project's goal was to design a Central Processing Unit (CPU) incorporating a fairly large instruction set and a multistage pipeline design with the potential to be used in a multi-core system. The CPU was coded and synthesized with Verilog. This was accomplished by building on the CPU design from fundamentals learned in CSE320 and increasing the instruction set to resemble a proper Reduced Instruction Set Computing (RISC) CPU system. A multistage pipeline was incorporated to the CPU to increase instruction throughput, or instructions per second. A major area of focus was on creating a multi-core design. The design used is master-slave in nature. The master core instructs the sub-cores where they should begin execution, the idea being that the operating system or kernel will be executing on the master core and the "user space" programs will be run on the sub-cores. The rationale behind this is that the system would specialize in running several small functions on all of its many supported cores. The system supports around 45 instructions, which include several types of jumps and branches (for changing the program counter based on conditions), arithmetic operations (addition, subtraction, or, and, etc.), and system calls (for controlling the core execution). The system has a very low Clocks per Instruction ratio (CPI), but to achieve this the second stage contains several modules and would most likely be a bottleneck for performance if implemented. The CPU is not perfect and contains a few errors and oversights, but the system as a whole functions as intended.

This project was centered around designing a processor model (using the C programming language) based on the Coldfire computer architecture that will run on third party software known as Open Virtual Platforms. The end goal is to have a fully functional processor that can run Coldfire instructions and utilize peripheral devices in the same way as the hardware used in the embedded systems lab at ASU. This project would cut down the substantial amount of time students spend commuting to the lab. Having the processor directly at their disposal would also encourage them to spend more time outside of class learning the hardware and familiarizing themselves with development on an embedded micro-controller. The model will be accurate, fast and reliable. These aspects will be achieved through rigorous unit testing and use of the OVP platform which provides instruction accurate simulations at hundreds of MIPS (million instructions per second) for the specified model. The end product was able to accurately simulate a subset of the Coldfire instructions at very high rates.

The purpose of this project was to program a Raspberry Pi to be able to play music from both local storage on the Pi and from internet radio stations such as Pandora. The Pi also needs to be able to play various types of file formats, such as mp3 and FLAC. Finally, the project is also to be driven by a mobile app running on a smartphone or tablet. To achieve this, a client server design was employed where the Raspberry Pi acts as the server and the mobile app is the client. The server functionality was achieved using a Python script that listens on a socket and calls various executables that handle the different formats of music being played. The client functionality was achieved by programming an Android app in Java that sends encoded commands to the server, which the server decodes and begins playing the music that command dictates. The designs for both the client and server are easily extensible and allow for any future modifications to the project to be easily made.

In this article we present a low-cost force-sensing quadrupedal laminate robot platform. The robot has two degrees of freedom on each of four independent legs, allowing for a variety of motion trajectories to be created at each leg, thus creating a rich control space to explore on a relatively low-cost robot. This platform allows a user to research complex motion and gait analysis control questions, and use different concepts in computer science and control theory methods to permit it to walk. The motion trajectory of each leg has been modeled in Python. Critical design considerations are: the complexity of the laminate design, the rigidity of the materials of which the laminate is constructed, the accuracy of the transmission to control each leg, and the design of the force sensing legs.

Image stabilization is a highly desired feature for many systems involving cameras. A camera stabilizer effectively prevents or compensates for unwanted camera movement to provide this stabilization. The use of stabilized camera technology on board aerial vehicles is one such application where the stabilization can greatly improve the overall capability of the system. The requirements for such a system include a continuous control algorithm and hardware to determine and adjust the camera orientation. The topic of developing an aerial camera control and electronic stabilization system is thus explored in the contents of this paper.

The purpose of this project was to create a modular embedded systems platform that would provide a hands-on lab experience for students learning about embedded systems protocols. The system would be designed to be modular, expandable, and productizable. Its modularity would eliminate errors in the design and make the entire system more robust. It would also be expandable, which means additional project boards could be created in the future without requiring a complete redesign of the system. And finally, productizing the entire system would allow it to be sold to other universities who may have a similar program that would benefit from a system such as the OCTOPUS.

The Coffee Hutch project is derived from the field of Computer Science and consists of a website, a database, and a mobile application for Android devices. This three-tiered scheme is designed to support a point-of-sale payment system to be integrated with a standalone product dispensing machine. The website contains landing pages which provide navigation and functional capabilities for users. The site also features a variety of PHP web services which communicate with the database using SQL commands. The application, programmed in the Java language, makes use of these services in a simple, utilitarian design aimed at modification of user data stored in the database. This database, developed with MySQL and managed with the phpMyAdmin application, contains limited information in order to maximize speed of read and write accesses from the website and Android app. Together, these three components comprise an effective payment management system model with mobile capabilities. All of the components of this project were built at no cost. The website hosting service is free and the third-party services required (such as Paypal payment services) are simulated. These simulations allowed me to demonstrate the functionality of the three-tiered product without the necessity for monetary supplication. This thesis features every aspect of the development and testing of The Coffee Hutch software components. Requirements for each function of the software are specified in one section, and they are aligned with various pieces of the code in the source documentation. Test cases which address each requirement are outlined in another section of the thesis.

This project is investigating the impact curvature, buckling, and anisotropy play when used passively to enhance jumping capability. In this paper we employ a curved structure to allow a rigid link to collapse preferentially in one direction when it encounters aerodynamic drag forces. A joint of this nature could be used for passively actuated jump gliding, where wings would collapse immediately on takeoff and passively redeploy during descent, allowing the jumping robot to extend its horizontal range via gliding. A passively actuated joint is simpler and more lightweight than active solutions, allowing for a lighter glider and higher jumps. To test this, several prototype collapsing gliding wings of different diameters were tested by dropping them from a consistent height above the ground and by launching them upwards and recording their initial velocity. A model was constructed in Python using the data gathered through the experiments and was tuned so that its outputs were as close as possible to the experimental results. As expected, increasing the wing diameter increased the total fall time, and increasing the payload mass decreased the total fall time. Orientation of the wings around the vertical axis of the glider relative to the direction of horizontal motion was also found to have an effect on the length of time between when the gliding platform was launched and when it made contact with the ground, with a configuration where the axis between the wings was parallel to the direction of motion granting added stability.

The Internet of Things has spread Wi-Fi connectivity to household and business devices everywhere. It is important that we understand IoT's risks and capabilities as its popularity continues to grow, and that we recognize new and exciting uses for it. In this project, the ESP8266 Wi-Fi controller, powered by a lithium battery, is used to transmit messages from a user's browser or mobile phone to an OLED display. The ESP8266 is a system on a chip (SOC) which boasts impressive features such as full TCP/IP stack, 1 MB of flash memory, and a 32-bit CPU. A web server is started on the ESP8266 which listens at a specific port and relays any strings from the client back to the display, acting as a simple notification system for a busy individual such as a professor. The difficulties with this project stemmed from the security protocol of Arizona State University's Wi-Fi network and from the limitations of the Wi-Fi chip itself. Several solutions are suggested, such as utilizing a personal cellular broadband router and polling a database for stored strings through a service such as Data.Sparkfun.com.
