Processor Modules For The Classroom Development Of Physical Computers, Lakshmi Ongolu
Processor Modules For The Classroom Development Of Physical Computers, Lakshmi Ongolu
Master’s Theses and Projects
Processors are present in almost all the electronic components available in the market now. As they perform trillions of operations per second and are complex internally. This project is to build building modules for students, who will be able to develop their own processor. The main idea is that this will help students to experience the detailed workflow of a processor and focus on design and development instead of spending time on wiring and soldering. Different components such as Program Counter, Instruction Register, Memory, Multiplexer, Adder and transceivers are designed and printed as individual modules on printed circuit boards (PCB’s). …

The Internet has made several giant leaps over the years, from a fixed to a mobile Internet, then to the Internet of Things, and now to a Tactile Internet. The Tactile Internet goes far beyond data, audio and video delivery over fixed and mobile networks, and even beyond allowing communication and collaboration among things. It is expected to enable haptic communications and allow skill set delivery over networks. Some examples of potential applications are tele-surgery, vehicle fleets, augmented reality and industrial process automation. Several papers already cover many of the Tactile Internet-related concepts and technologies, such as haptic codecs, applications, …
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.
Posits: An Alternative To Floating Point Calculations, Matt Wagner
Posits: An Alternative To Floating Point Calculations, Matt Wagner
Theses
Floating point arithmetic is one of several methods of performing computations in digital designs; others include integer and fixed point computations. Fixed point utilizes a method comparable to scientific notation in the binary domain. In terms of computations, floating point is by far the most prevalent in today’s digital designs. Between the support offered by compilers, as well as for ready-to-use IP blocks, floating point units (FPU’s) are a de-facto standard for most processors. Despite its prevalence in modern designs, floating point has many flaws. One of the most common is the use of not-a-numbers (NaN’s). These are meant to …
The Design Of A Custom 32-Bit Risc Cpu And Port To Gcc Compiler Backend, Danielle Megan Fischer
The Design Of A Custom 32-Bit Risc Cpu And Port To Gcc Compiler Backend, Danielle Megan Fischer
Theses
This paper presents the design of a 32-bit RISC processor, which is then mapped to the backend of GCC so basic C code can be compiled successfully to the processor. There are many design decisions that go into the construction of a processor. The instruction set architecture gives away a lot of information regarding the individual instructions that the processor will have, the memory architecture, as well as how I/O peripherals will be handled. Additionally, the hardware implementation of the processor needs to be kept in mind when crating the design. Pipelining can often help with processor speed, while cache …
Spatial Indexing For System-Level Evaluation Of 5g Heterogeneous Cellular Networks, Roohollah Amiri, Eren Balevi, Jeffrey G. Andrews, Hani Mehrpouyan
Spatial Indexing For System-Level Evaluation Of 5g Heterogeneous Cellular Networks, Roohollah Amiri, Eren Balevi, Jeffrey G. Andrews, Hani Mehrpouyan
Electrical and Computer Engineering Faculty Publications and Presentations
System level simulations of large 5G networks are essential to evaluate and design algorithms related to network issues such as scheduling, mobility management, interference management, and cell planning. In this paper, we look back to the idea of spatial indexing and its advantages, applications, and future potentials in accelerating large 5G network simulations. We introduce a multi-level inheritance based architecture which is used to index all elements of a heterogeneous network (HetNet) on a single geometry tree. Then, we define spatial queries to accelerate searches in distance, azimuth, and elevation. We demonstrate that spatial indexing can accelerate location-based searches by …

Sam-Sos: A Stochastic Software Architecture Modeling And Verification Approach For Complex System-Of-Systems, Ahmad Mohsin, Naeem Khalid Janjua, Syed M. S. Islam, Muhammad Ali Babar
Research outputs 2014 to 2021
A System-of-Systems (SoS) is a complex, dynamic system whose Constituent Systems (CSs) are not known precisely at design time, and the environment in which they operate is uncertain. SoS behavior is unpredictable due to underlying architectural characteristics such as autonomy and independence. Although the stochastic composition of CSs is vital to achieving SoS missions, their unknown behaviors and impact on system properties are unavoidable. Moreover, unknown conditions and volatility have significant effects on crucial Quality Attributes (QAs) such as performance, reliability and security. Hence, the structure and behavior of a SoS must be modeled and validated quantitatively to foresee any …
