P ROJECTS (REFERENCES ARE TO THE RELEVANT PAPERS LISTED IN THE PUBLICATIONS SECTION)

A Functional IA32 Processor Core [5] (August 2004 Present)

Develop a functional IA32 processor core in HDL (i.e. VHDL, BlueSpec) to be used as the CPU model for TRUSS [1]

prototype. Bochs IA32 software emulator is used as behavioral reference. Xilinx ISE and ChipScope are used for synthesis and

debugging. Current version of the core runs several simple user-level applications (e.g. Dhrystone) on Virtex2Pro FPGA.

Hardware Support for Checkpointing [3] (September 2004 Present)

Explore architectural designs and requirements for checkpointing memory states to allow for a long window of speculation with

multiple outstanding checkpoints. Such support can potentially be useful for various application areas, such as transactional

memory, very aggressive speculation schemes, reliability, and debugging. RSIM, Simics, and Flexus software simulators have

been used for evaluation at different phases of the project.

FPGA-based Cache Emulation and Workload Characterization [4,6,10,11,15] (July 2003 July 2004)

Worked on FPGA-based cache emulation at Intel MRL under the guidance of Dr. Shih-Lien Lu. Two emulators were

developed: (1) PHA$E, which sits on a system bus of a real system host, collects memory traces, and performs L3 cache

modeling in real-time. (2) ACE, which injects delays to the system in addition to collecting traces, effectively modeling the

latencies of the experimental L3 cache being emulated, as experienced by its time dilated real system host. These emulators were

used to conduct various workload characterization studies. See reference publications for details.

Fast and Efficient Handoff for Cellular IP Network [2,8] (January 2002 June 2004)

Devised a new handoff scheme for Cellular IP network that reduces both latency and traffic compared with the handoff

schemes originally proposed for Cellular IP. NS2 software simulator were used for evaluation.

Low Power Video Decoding Using Dynamic Voltage Scaling [7,12] (January 2002 December 2003)

Investigated dynamic voltage scaling techniques for low-power video decoding. Simplescalar and Wattch software simulator

were used as the evaluation framework.

A mobile phone survey in US and Japan [9,14] (April 2002 December 2002)

Conducted a survey about mobile phone usage among university students in US and Japan. 315 respondents participated from 8

universities in urban and rural areas in US and Japan (Portland, Corvallis, Tokyo, Ehime, Okinawa).

Multimedia-Capable Campus Network (August 2001 March 2002)

Explored ways to create multimedia-capable campus network by means of Cellular IP and multimedia proxies. The project was

selected as a finalist of the national research contest held by Intel (http://www.intel.com/research/awards/).

Online Project Manager (Senior Design Project, September 2000 May 2001)

Led a team of four in the design and development of an information-based system that can manage engineering projects online.

The system was built on MS SQL server on Windows 2000 utilizing ASP, HTML, SQL and JavaScript.

Web administration tool (June 2000 August 2000)

Created a CGI program using Perl and SQL to administer users in a proprietary web-based tool for Sun Microsystems, Inc.

Implemented functionalities such as adding, modifying and showing user profile.

JavaBeavs Screen Saver (January 2000 May 2000)

Developed a screensaver program using Java (Visual J++) that shows graphics and texts promoting Oregon State University.

The team won the 3rd place in the 1st OSU ACM annual software contest.
