Going From C to MIPS AssemblyBasic Operations: Loops , ConditionalsCharles Gordon(Version , September 2000)1 OverviewAt this point in the course, you should be reasonably familiar with the Basic concepts ofMIPS Assembly . This includes registers, instruction formats, addressing, and basicarithmetic and load/store operations. It might be good to review the first four sections ofchapter 3 if you are still uncomfortable with these concepts. This guide will focus on thenext step in learning Assembly : conditional statements and If/Then/Else StatementsA generic if/then/else construct from C is given in figure It consists of aconditional check followed by two possible code blocks.

3 Loops There are three distinct types of loops in C: do/while, while and for. It may come as a surprise to some of you that they are all functionally identical. In other words, you can take any for loop and turn it into a while loop with a bare minimum of effort. The different forms merely capture the different uses of loops. Figure 3.1 lists ...
