SSE2 (Streaming SIMD Extensions 2) is one of the Intel SIMD (Single Instruction, Multiple Data) processor supplementary instruction sets introduced by Intel with the initial version of the Pentium 4 in 2000. SSE2 instructions allow the use of XMM (SIMD) registers on x86 instruction set architecture processors.
In computing, Streaming SIMD Extensions (SSE) is a single instruction, multiple data instruction set extension to the x86 architecture, designed by Intel and introduced in 1999 in its Pentium III series of central processing units (CPUs) shortly after the appearance of Advanced Micro Devices (AMD's) 3DNow!.
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.
SIMD instructions can be found, to one degree or another, on most CPUs, including IBM's AltiVec and SPE for PowerPC, HP's PA-RISC Multimedia Acceleration eXtensions (MAX), Intel's MMX and iwMMXt, SSE, SSE2, SSE3 SSSE3 and SSE4.x, AMD's 3DNow!, ARC's ARC Video subsystem, SPARC's VIS and VIS2, Sun's MAJC, ARM's Neon technology, MIPS' MDMX (MaDMaX ...
In the x86 assembly programming language, MOVAPD is the name for a specific action performable by modern x86 processors with 2nd-generation Streaming SIMD Extensions (SSE2). This action involves copying a pair of numbers to temporary space in the processor for use in other computations.
All models support: MMX, Streaming SIMD Extensions (SSE), SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, Advanced Vector Extensions (AVX), Enhanced Intel SpeedStep Technology ...
Framewave consists of the following main components: [4] Simple interface to take advantage of latest hardware innovations MMX; Streaming SIMD Extensions (SSE), SSE2; Multi-core processors
SSE2 Streaming SIMD Extensions 2 support. A 10- or 12-stage Enhanced instruction pipeline that allows for higher clock speeds without lengthening the pipeline stage, reduced from 14 stage on Pentium Pro/II/III.
