Welcome to the Scalable Energy-efficient Architecture Lab

The Scalable Energy-efficient Architecture Lab (SEAL) is a research group at The University of California, Santa Barbara. SEAL research focuses on, but not limited to, VLSI design, electronic design automation, computer architecture, compiler, programming langauage, and  systems design. Current research projects include domain specific accelerator, novel memory architecture, interconnect architecture, and heterogeneous system architecture.  Specifically, recent research projects focus on technology-driven and application-driven design/architecture innovations. The technology-driven research projects include EDA/architecture for emerging memory technologies and 3D integrated circuits,  and heterogeneous computing with CPU/GPU/FPGA. The application-driven research projects include novel architectures for artificial intelligence (AI), such as computer architecture for deep learning neural network, and bio-inspired computing, hardware acceleration for emerging applications such as bio-informatics applications, graphics analytics, and VR/AR applications.

Artificial Intelligent algorithms are exerting an evolutionary influence on human society covering a wide spectrum of applications, including image recognition, speech understanding, robots intelligence, traffic control, and data analytics. The improving performance of Artificial Intelligent... more
A three dimensional (3D) chip is a stack of multiple device layers with direct vertical interconnects tunneling through them. A key benefit of this approach over a traditional two dimensional chip is the ability to reduce the length of long interconnects.
In recent years, emerging non-volatile memory (NVM) technologies, e.g., Phase-Change RAM (PCRAM), STT-RAM (MRAM) Resistive RAM (RRAM), and Memristors, have gained substantial attentions and a
The challenges in fabricating transistors with diminutive feature sizes in the nanometer regimes have resulted in significant variations in key transistor parameters, such as transistor channel length, gate-oxide thickness, and threshold voltage. This manufacturing variability can  cause... more
Process scaling and aggressive performance improvements have resulted in power consumption becoming a first-order design criterion. For example, the latest Intel Pentium 4 processor (Prescott, 2004) has a power consumption of 103 Watts, almost four times larger than that of the Pentium III (1999).... more
Embedded systems are of great economic importance. Embedded applications include consumer electronics appliance, signal processing, automobile control, aircraft autopilot, and so on. It is estimated that the embedded system market sales was approximately $46 billion in 2004 and expected to grow at... more
