Could you open "the search with pure C/C++ implementation to compute hamming distance" codes?

Hi,
according to this project README.md description. The "Correction of computational cost" sections says you computes hamming distance between two 64-bit binary codes takes 23 ps (bitwise XOR operation). when i use C/C++ to achieve this process, and find compute hamming distance between two 48-bit binary codes takes 0.02us. so could you open this codes?
Thanks
