Pintos was developed with an intention to introduce undergraduate students to concepts in operating system design and implementation by requiring them to implement significant portions of a real operating system, including thread, memory management and file system.
This work involves transformation of the primitive Pintos kernel into a modern UNIX-like kernel called Burritos. Throughout the process of transformation “from Pintos to Burritos”, we have strengthened Pintos’s support in three key areas – process, memory and file management, which has taken us to a level of understanding that merely reading the code couldn’t have provided.
