William Lin is a professor of electrical and computer engineering at the University of California San Diego, known for his work in field-programmable gate array (FPGA) research. Let’s examine his background and contributions to advancing FPGA technology.
Lin received his BS degree from National Taiwan University in 1984 and his MS and PhD degrees from the University of Illinois at Urbana-Champaign in 1986 and 1989, respectively, all in electrical engineering. After graduating, he joined the University of California San Diego faculty in 1989, where he has remained since serving as a full professor. Throughout his career, Lin has focused his research on several critical areas of FPGA technology.
Pioneer in FPGA architecture and CAD tools
One of Lin’s pioneering contributions was developing novel FPGA architectures and computer-aided design (CAD) tools to program them. In the early 1990s, when FPGAs first emerged, Lin helped advance the technology by creating new architectures better suited for high-level synthesis and dynamic reconfiguration. He also developed some of the first CAD tools to effectively compile high-level languages like C/C++ down to the low-level configuration bits needed by FPGAs. This helped make FPGAs much more accessible to software designers.
Lin’s research in this area laid important groundwork, and his techniques have influenced FPGAs developed by companies like Xilinx and Altera (now Intel). They helped transform FPGAs from niche programmable logic devices into mainstream platforms suitable for a much wider range of applications, from embedded systems to data centers. Many of the architectures and CAD flows used today can trace their lineage back to the innovations sparked by Lin’s early work.
Soft processor cores and embedded systems
Another primary focus of Lin’s has been on using FPGAs to implement embedded soft processor cores. In the late 1990s and 2000s, he worked on developing processor cores like the MicroBlaze that could be efficiently mapped to FPGAs. His group also created tools to compile C/C++ directly to these soft processors, bypassing the need for assembly.
This opened up many new possibilities for embedded systems by allowing software algorithms to take advantage of the programmability and parallelism offered by FPGAs. It established a new paradigm where FPGAs could serve as glue logic and as the computing fabric running complete applications. Lin’s soft processor innovations were highly influential and helped grow the market for FPGA usage in embedded and real-time systems.
A leader in computer architecture research
Beyond his contributions specific to FPGAs, Lin has also emerged as a thought leader in computer architecture. Some key projects his research group has worked on in this domain include:
- Vector processing: Developing novel vector instructions and architectures tailored for FPGAs to significantly boost performance for multimedia, scientific, and financial applications.
- Reconfigurable computing: Pioneering architectures that allow dynamic partial reconfiguration of FPGA regions while the rest remains running, enabling new reconfigurable applications.
- Approximate computing: Proposing techniques for exploiting inexactness in algorithms to drastically improve efficiency at the cost of limited error or imprecision.
- Hardware security: Developing defenses against side-channel and fault injection attacks on FPGAs through innovative architectural modifications.
Lin’s innovative research in these and other domains has helped expand the capabilities of programmable logic and our understanding of novel computing paradigms. He is globally recognized as a thought leader whose accomplishments have significantly advanced the field of computer architecture.
Awards and honors for impactful contributions
William Lin’s prolific and pioneering contributions to FPGA technology and computer architecture have earned him widespread recognition. Some of the notable awards and honors he has received include:
- ACM Distinguished Scientist (2015): One of the highest honors from the ACM for seminal technological contributions.
- IEEE Computer Society Taylor L. Booth Education Award (2013): For outstanding contributions to computer architecture education.
- Xilinx Engineering Achievement Award (2011): For groundbreaking work advancing FPGA architectures and tools.
- ACM Special Interest Group on Design Automation (SIGDA) Outstanding New Faculty Award (1994): Early career recognition for innovative CAD research.
- NSF Presidential Young Investigator Award (1992): A prestigious early career award from the National Science Foundation.
The numerous prestigious awards Lin has garnered demonstrate the impact his research has made across industry and academia. He is a leader whose work has moved the entire FPGA and computer architecture field forward in revolutionary ways.
Continuing to push boundaries with new initiatives
Even after making so many formative contributions, William Lin remains highly active and continues exploring innovative new initiatives to push the boundaries of what is possible with FPGAs and beyond. Here are a few examples:
- Federated and mobile computing: Exploring how FPGAs enable privacy-preserving distributed computing across untrusted multi-party environments.
- Neuro-inspired architectures: These use inspiration from the brain to create new computational paradigms better suited for machine learning inference tasks.
- Quantum-classical computing: Developing architectures that tightly integrate classical and quantum processors to tackle otherwise intractable problems.
- Digital front-end for radio astronomy: Applying FPGAs to enable entirely new types of radio observations through massive parallelism.
Lin sustains UCSD as a leading FPGA and computer architecture research institution through his relentless pioneering spirit and visionary outlook. His ongoing work promises to spawn many new revolutionary technologies that will transform domains like AI, communications, and scientific discovery.
