Computer Labs 2015/2016 - 1st Semester
Lab 2: The PC's Timer

1. Objective

The objective of this lab is twofold. First that you learn how to use the PC's timer. Second that you understand the concept of interrupt, and learn how to use it in the context of this lab.

This handout is structured as follows:

• 2- What to do?, which summarizes what you have to do in this lab, and what you should do in order to prepare it.
• 3- The PC's Timer, which describes the I/O device that is the object of the lab.
• 4- The PC's Interrupt HW, which describes the way interrupts are handled in the PC.
• 5- Minix 3 Notes, which describes some aspects of the Minix 3 kernel that are relevant to this lab (and also future labs).
• 6- Functions' Specification
• 7- Coding/Development
• 8- Compilation
• 9- Configuration
• 10- Execution
• 11- Submission
• 12- Grading criteria
