A simple shell in C

Project for 2023/2024 - Computer Organization @ IST

A UNIX-Shell made in C using fork(),pipe(),exec() and wait() system calls

Computer Architecture

This project takes in up to 4 lines of MIPS code, identifies any pipelining hazards, and prints the timing diagram with and without a data forwarding unit.

This project aims to Recursively Resolving DNS records through a local server which can be hosted on an SBC. It provides Domain-Name-To-IP-Translation, and Canonical[CNAME] Alias Translation. DNS Resolution and Forwarding control is brought to the client, and is fit for DNS Packet Analysis.

The Rip Van saWinkle architecture implements a pipelined CPU design. A pipelined CPU implementation segments the data path into distinct stages that allows for multiple instructions to be in flight simultaneously. Staging of the data path has an immense comparative advantage to non-pipelined implementations in terms of performance at the cost of…

This is a shell, written in C, that supports all the built-in commands that exist in the linux shell. It also supports pipelining of up to three commands. Written in one week, there are a lot of room for improvement and better ways to organize the code (work in progress).
