Pintos Operating System - Threads & User Programs C Feb 2025 – Apr 2025

• Implemented key OS concepts including thread scheduling, priority inversion handling (via priority donation), nested priority donation, and load-based scheduling (MLFQS) by modifying Pintos kernel.

• Replaced the default round-robin scheduler with a priority-based scheduler, ensuring starvation-free thread management.

• Extended the Pintos kernel to support loading and execution of user programs from ELF binaries with proper synchronization.

• Implemented 13 system call handling, including argument passing, memory validation, and file operations. Text Chat Application C++ Mar 2025 – Apr 2025

• Developed a TCP-based client-server chat application using C and the select system call for I/O multiplexing

• Implemented a custom shell-like interface to support real-time message exchange and command parsing

• Managed multiple simultaneous client connections efficiently without multithreading, leveraging select .

• Handled robust error-checking, socket cleanup, and edge cases for stable communication. 16-bit Single-Cycle Processor Verilog, Vivado, Basys 3 FPGA Mar 2025 – Apr 2025

• Designed and implemented a 16-bit single-cycle, non-pipelined CPU supporting arithmetic, logic, memory, branch, and jump instructions.

• Developed core modules including Program Counter, ALU, Control Unit, and Register File; verified correctness through simulations in Vivado.

• Verified the processor on a Basys 3 FPGA board, interfaced with physical I/O (buttons, LEDs) to demonstrate instruction execution and register updates.
