  1. Hi, This question is regarding the SSE macro function for shuffle operations. I don't understand it fully. MSDN says that _MM_SHUFFLE(z,y,x,w) expands to : (z << 6) | (y <<4) | (x << 2) | w This macro is used in conjunction with SHUFPS or MMX instrinsic function _mm_shuffle_ps(m1, m2, int mask), where mask is replaced by the macro that acts on m1 and m2
  2. _mm_shuffle_epi8(a, mask) rearrange the bytes of a according to mask and return the result. mask is a vector of 8-bit integers (type __m128i) that indicates how to rearrange each byte: if a byte in the mask has the high bit set (is greater than 127), then the corresponding byte of the output is 0; otherwise, the byte number specified in the input is copied to the corresponding byte of the.
  3. History. SSSE3 was first introduced with Intel processors based on the Core microarchitecture on June 26, 2006 with the Woodcrest Xeons.. SSSE3 has been referred to by the codenames Tejas New Instructions (TNI) or Merom New Instructions (MNI) for the first processor designs intended to support it.. Functionality. SSSE3 contains 16 new discrete instructions

Fast Base64 encoding/decoding with SSE vectorization. October 29, 2014. In this installment of SSE vector programming for fun and profit, we're going to write a Base64 encoder that's about four times faster than everything else available. The results of this process can be found in my Base64 library at GitHub, which is licensed under the BSD 2-clause. Before we get to Base64, we have to take. UTF-8 processing using SIMD (SSE4) SIMD: Single instruction, multiple data is a class of instructions present in many CPUs today. For With that information, we can use _mm_shuffle_epi8 (SSSE3) to shuffle the vector and remove the gaps. Then we can unpack the result and store it, and we are almost done. __m128i shuf = _mm_add_epi8(shifts, _mm_set_epi8(15,14,13,12,11,10,9,8,7,6,5,4,3,2,1. A new scheme for SIMD in Rust is available in the latest nightly compilers, fresh off the builders (get it while it's hot!).. For the last two months, I've been interning at Mozilla Research, working on improving the state of SIMD parallelism in Rust: exposing more CPU instructions in the compiler, and an in-progress library that provides a mostly-safe but low-level interface to that core.
