Wojciech Muła, a Polish computer scientist and software developer educated from Rzeszów University of Technology in electrical engineering and computer engineering [1], with expertise in low level programming, bit-twiddling and performance optimization, in particular SIMD and SWAR techniques applied to string search, population count, Base64 and various algorithms. In 2008, Wojciech Muła introduced a SSSE3 population count based on a pair of PSHUFB 16 parallel nibble in-xmm register lookups [2], in the meantime due to AVX2 or AVX-512 even possible with doubled or fourfold register widths, competing the native x86-64 popcount instruction [3]. He is further contributor on the Polish Wikipedia [4].
