Research

Alleviating Data Fragmentation in Deduplication Systems

• July 2023 – January 2025
• Accepted by EuroSys 2025. Full paper available at ACM Digital Library.

Projects

4th “Loongson Cup” National Student Computer System Capability Challenge (NSCSCC 2020)

• March 2020 – August 2020
• Group project by 4 participants. I am mainly in charge of pipeline implementation.
• Designed and implemented a dual-issue 6-stage pipelined MIPS processor. We did timing analysis for critical paths and optimized for low latency accordingly.
• Multiplication is conducted by a Wallace tree multiplier, divided into two stages and optimized for low latency with CSAs (carry-save adders).
• The final processor is clocked at 88 MHz and the instructions per cycle is 34.4 times that of gs132 (the baseline processor) and awarded the first prize.
• Implemented a controller for VGA and can cooperate with other peripherals by software code.
• Can run pmon (a bootloader provided by the committee) and run software code from pmon.
• Our code is hosted on GitHub. Follow this link for more details.
