CSC231 Exercises with conditional jumps

Exercises on Conditional Jumps

Finding the minimum

Find the minimum of 3 signed int variables a, b, and c

Loop until overflow

Print fibonacci numbers coded as unsigned words until the result overflows. Don't print erroneous numbers!

Scanning an array

Find the largest element of a 1-dimensional array of integers.

Characters and lower/upper case conversion

Write the code necessary to transform a character from lower- to upper-case, if the character is a letter. The character should not be changed if it is not a letter.

Characters and lower/upper case conversion. Version 2

Use a boolean function that returns true or false depending on whether the character it receives is lowercase or not.

Long/short jumps

Conditional jumps can jump only +127 bytes down, -128 bytes up in the code. How can we code something like this:

                 cmp     eax,10
                 jl      there
                 ...
                 ...
        there:   ...

when the instruction at Label there is 1000 bytes away from the jl conditional jump?
