Semester Projects

  • [CS 109] Dark Chess: Dark chess game implemented in Java using Swing GUI, a rookie project.
  • [CS 202] MineCPU: Standard 5-stage pipeline RISC-V CPU implemented in SystemVerilog, with cache and branch prediction as performance optimization, verified by Verilator and Unicorn simulator. As verification of functionality, the project implements a simple game, Pacman, written in C++ and cross-compiled to RV machine code. The I/O interface is integrated into the CPU and driven by MMIO.
  • [CS 207] Piano by FPGA: Another rookie project introducing FPGA and Verilog, intended for learning digital design. It’s a simple piano running on FPGA with auto-play, learning and free-play modes. Developed on my own.
  • [CS 301] GISC Embedded UNDER DEVELOPMENT
  • [CS 305] HTTP File Manager: Remote file manager implemented in Python to enhance the understanding of HTTP protocol along with TCP/IP for computer networks. The framework is built from scratch since the instructor requires no third-party libraries.
  • [CS 309] NINJA Chat UNDER DEVELOPMENT
  • [CS 323] Incredibuild Compiler UNDER DEVELOPMENT
  • [SWS 3011] GoFetch Demo & Mitigation: A educational website developed to give a first glance at the side-channel attack, and animate the GoFetch attack. The mitigation is also provided to show a possible hardware and software solution to defend against the attack. Meanwhile the overhead of the mitigation is also discussed.

Notes

  • CS Notes @SUSTech: Course notes and materials during my undergraduate study at SUSTech, mainly for computer science.
  • Write Up for CTF: Collection of my personal writeups (aka solutions) for CTF challenges. I’ve also post them on the blog.
  • Slides @Slidev: Slides for presentations, mainly for academic purposes.
