The problem to be solved and implemented with an ARM assembly language program

You are asked to do some image processing on an image composed of characters shaped in

For example, a 9 - 6 image may look like the one shown in Figure 1, which, more or less, looks like a representation of the letter "F" (you will not be using colour, however).

This is a subset of the C program in assignment 1. It should focus you to learn ARM programming, since you are completely familiar with the problem and indeed you can use the previous C code as your guideline pseudo-code when designing your ARM program. Also feel free to use the C code provided as a general answer to all and posted on the course web pages.

The program is expected to read from an input file an image described by integers, convert each integer appropriately to a character, do some image processing tasks on the character image, and print the results.

The functional requirements were explained in the previous assignment. Here you will be rotating the image right by 90 degrees and then scaling it up doubling its size using the second (vector-based) algorithm which you used in your previous C program. Doing both tasks may prove to be too challenging at this point in your learning path, so you are given a choice of which task to implement and submit. Should you be able to submit both, you will receive an extra 30 marks bonus (that is, instead of 50 marks you could earn 80). Read the expectations carefully, both for the design and for the technical details. An initial template file is also given to you, with some of the code already provided. Make sure you analyze it carefully and customize it appropriately, including the comments.
