Over the past decades, Single Instruction, Multiple Data (SIMD) instructions have become common- place in conventional hardware. Lexical analysis, the first stage of compilation, can take advantage of this by splitting its workload across sub lexers that identify groups of tokens with similar structures. Each sub lexer can leverage SIMD to search for these structures across multiple characters in paral- lel and extract token positions efficiently. This pa- per presents a lexer with this architecture for the C programming language, along with implementation details for x86/x64 processors. Benchmark results show a 12x speed up in throughput compared to the lexer found in GCC, a state-of-the-art compiler.
