This article delves into how to convert high-level conditional statements (such as greater than, greater than or equal, and less than or equal) into efficient machine code in MIPS assembly language, using only the slt (set on less than), beq (branch if equal), and bne (branch if not equal) instructions. Through analysis of a specific pseudocode conversion case, the paper explains the design logic of instruction sequences, the utilization of conditional exclusivity, and methods to avoid redundant branches. Key topics include: the working principle of the slt instruction and its critical role in comparison operations, the application of beq and bne in conditional jumps, and optimizing code structure via logical equivalence transformations (e.g., implementing $s0 >= $s1 as !($s0 < $s1)). The article also discusses simplification strategies under the assumption of sequential execution and provides clear MIPS assembly examples to help readers deeply understand conditional handling mechanisms in low-level programming.
