An algorithm that uses common SIMD instructions to perform high-performance string comparing
Most SIMD instructions have specific 8-bit logic instructions, which can be used for fast comparing. Here, we look at the logic of an algorithm, then discuss how SIMD instructions can be used with C-strings to make the code run faster.
