Otter Vector Extension, Alexis A. Peralta
Otter Vector Extension, Alexis A. Peralta
Computer Engineering
This paper offers an implementation of a subset of the "RISC-V 'V' Vector Extension", v0.7.x. The "RISC-V 'V' Vector Extension" is the proposed vector instruction set for RISC-V open-source architecture. Vectors are inherently data-parallel, allowing for significant performance increases. Vectors have applications in fields such as cryptography, graphics, and machine learning. A vector processing unit was added to Cal Poly's RISC-V multi-cycle architecture, known as the OTTER. Computationally intensive programs running on the OTTER Vector Extension ran over three times faster when compared to the baseline multi-cycle implementation. Memory intensive applications saw similar performance increases.

Quality testing is an important part of the wine industry. Without proper quality control, thousands of dollars could be wasted on bottling and recalling hundreds of gallons of wine. Due to this, labs are set up that collect wine samples from the tanks in a wine production plant and test them. A big part of this testing is determining exactly what tanks need to be tested and what tanks are at risk. My project aims to help automate this task by collecting data from the tanks wirelessly and keeping track of simple indicators such as pH and temperature. Automating this …

Electrical Engineering
Electronics testing requires lengthy data collection and analysis. Streamlining at least part of this process allows resource reallocation, and faster data processing. Verifying a signal’s efficiency is key specification for a component’s datasheet. This project focuses on streamlining data collection when measuring a device’s output current. It combines amplifier design and digital interfacing to perform monitor a device’s output current. A computer-enable interface displays a graphical output current representation. It ensures accurate, high speed, high current measurements while removing a person’s need to manually plot data after testing. A new testing method provides room for company and product growth with …
The Characterization Of Effective Electromagnetic Fields On The Safety And Quality Of Low-Moisture Foods (Effs) - Prototype Device Development, Joe G. Sandoval
The Characterization Of Effective Electromagnetic Fields On The Safety And Quality Of Low-Moisture Foods (Effs) - Prototype Device Development, Joe G. Sandoval
Electrical Engineering
Contamination of low-moisture foods including flour, wheat grain, baby formula, and more, have increasingly become a concern due to sanitizing challenges. While industrial food processors have long used RF heating to sanitize mass quantities, an equivalent consumer device is absent from the market today. The Characterization of Effective Electromagnetic Fields on the Safety and Quality of Low-Moisture Foods (EEFS) project is an interdisciplinary effort to develop an RF heating consumer device to sanitize low-moisture foods.
A prototype device was designed to sanitize low-moisture food items using RF heating acceptable for commercial or consumer applications.

There are three main parts of this system: micro-controller, database, and website. Micro-controller detects motion of people walking in and out and It also measures room temperature and humidity in a confined space then updates collected data to the database. Our system’s database contains 6 main columns: room number, room capacity, number of students, temperature in Celsius, humidity in percent and date created. Finally, this database is queried by the website to display the information on the webpage. Users could also navigate on our site to check the most and least occupy rooms, and they can also search for a …

Tiny Disco: A Cost-Effective, High-Fidelity Wireless Audio System, Luke Martin Liberatore
Computer Engineering
The Tiny Disco is a WiFi based concert system, featuring improvements on popular “Silent Disco” concerts. Rather than being tied to compression and bandwidth restrictions present in traditional silent disco systems, the Tiny Disco system can deliver 320kbps+ audio quality, and allows listeners to bring their own headphones, further lending to the high quality audio experience.
Tiny Disco uses a Raspberry Pi as the audio server, and Espressif ESP32 microcontrollers as audio receivers/clients. The Tiny Disco is primarily geared toward smaller concerts and niche events where audio quality is valued, though due to its WiFi-based architecture, it can be expanded …
