Home * Hardware * x86 * SSE

SSE (Streaming SIMD Extensions),
were introduced by Intel in 1999 in their Pentium III series of processors. SSE provides an instruction set on eight 128-bit xmm registers xmm0..xmm7, with x86-64 expanded to 16 registers xmm0..xmm15, keeping vectors of four floats. Further, as a reply to AMD's 3DNow!, SSE introduced a few integer instructions extending the MMX instruction set.


The SSE2 instruction set as major enhancement to SSE, offers a more orthogonal set of instructions with vectors of four floats or two doubles, as well as integer vectors of 16 bytes, eight words, four double words or two quad words.
