BSAFE C toolkits uses AVX and AVX2 where appropriate to accelerate various cryptographic algorithms. [46] Crypto++ uses both AVX and AVX2 when available to accelerate some algorithms, like Salsa and ChaCha. OpenSSL uses AVX- and AVX2-optimized cryptographic functions since version 1.0.2. [47] Support for AVX-512 was added in version 3.0.0. [48]
SSE3, Streaming SIMD Extensions 3, also known by its Intel code name Prescott New Instructions (PNI), [1] is the third iteration of the SSE instruction set for the IA-32 (x86) architecture. Intel introduced SSE3 in early 2004 with the Prescott revision of their Pentium 4 CPU. [ 1 ]
The AVX-512 instructions are designed to mix with 128/256-bit AVX/AVX2 instructions without a performance penalty. However, AVX-512VL extensions allows the use of AVX-512 instructions on 128/256-bit registers XMM/YMM, so most SSE and AVX/AVX2 instructions have new AVX-512 versions encoded with the EVEX prefix which allow access to new features ...
The x86 instruction set has several times been extended with SIMD (Single instruction, multiple data) instruction set extensions.These extensions, starting from the MMX instruction set extension introduced with Pentium MMX in 1997, typically define sets of wide registers and instructions that subdivide these registers into fixed-size lanes and perform a computation for each lane in parallel.
This capability, known as horizontal in Intel terminology, was the major addition to the SSE3 instruction set. AMD's 3DNow! extension could do the latter too. SSSE3 , Merom New Instructions (MNI), is an upgrade to SSE3, adding 16 new instructions which include permuting the bytes in a word, multiplying 16-bit fixed-point numbers with correct ...

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.
