In this lab, we will learn about techniques available to application programmers for using logical address spaces that are not as widely known or used as they probably should be.

Issues addressed by this lab include:

• Understand the concept of Memory Mapped I/O
• Understand the difference between accessing data in a file using read/write system calls and using Memory Mapping

1. Slides
2. Lab Files

For this lab, you should complete the implementation of the memmap program. This program should create a memory mapping of the source and destination files. Copy the source file using memory operations and compare this approach to the read/write system call approach taken by the read_write program. Use the time command in comparing the work done by the two approaches under different operating conditions.

We should be able to build the your solution memmap program using the Makefile submitted in your solution zip file.

Once you are done with the lab, compress your source code and submit the compressed file through Canvas.
