Computer Architecture

The continuous improvements in single-core CMOS architecture performance that has driven our entire computing industry for decades is now broken irreparably. Computer Architecture research at UCSB is defining with the way that future generations of computing machines will be organized and designed in this new era. We push the frontiers of Computer Architecture by taking an interdisciplinary and cross-cutting approach which aims to bring the best advancements in both software (algorithms, compilers, operating systems, languages, machine learning) and hardware (circuits, devices, materials, and integration) together to transform what is possible with a machine. From the smallest 8-bit microcontroller, to the largest warehouse-sized data center, to the most powerful quantum computers, UCSB is providing the architectural solutions necessary to drive computing innovation.

Dr. Chong’s research redefines computer architectures and systems in the context of new technologies and application domains.  His current research focuses on emerging technologies for computing, multicore and embedded architectures, computer security, and sustainable computing.

Dr. Franklin works in three areas – architecture, computer science education, and gender diversity.  In architecture, her main focuses are microarchitecture, caches, and DRAM,especially for parallel systems.  She is currently looking at new technologies (i.e. memristors), how to mitigate their disadvantages, and how to harness their advantages to transform how applications run on modern processors.  In computer science education, she partners with an education colleague to develop curriculum for 4th-6th graders in oder to study how they learn computing concepts.

The end of classical transistor scaling laws (i.e. Dennard Scaling) means that radical new approaches to computing systems are desperately needed.  Professor Sherwood and his lab have been developing systems for this new era which use application-customization to achieve efficiency, exploit new devices and materials for new computational abilities, and attempt to provide functionality beyond performance such as provable security properties. 

Prof. Zheng’s research interests lie in the general area of wireless networking and systems, with particular focus on wireless data centers, smartphone systems, and dynamic spectrum access systems. She has also been actively working on social networks and graph analysis.
