SSSE3

SSSE3

Supplemental Streaming SIMD Extension 3 (SSSE3) is Intel's name for the SSE instruction set's fourth iteration. The previous version was SSE3, and Intel have added an "S" rather than increment the version number, as they appear to consider it merely a revision of SSE3. Before Intel used the official name, it was often mistakenly referred to as SSE4 (which has caused some confusion in the community). It has also been referred to by the code names Tejas New Instructions (TNI) or Merom New Instructions (MNI) for the first processor designs intended to support it. Introduced in Intel's Core Microarchitecture, SSSE3 is available in the Xeon 5100 series (Server and Workstation) processors and the Intel Core 2 (Notebook and Desktop) processors.

SSSE3 contains 16 new discrete instructions over SSE3. Each can act on 64-bit MMX or 128-bit XMM registers. Therefore, Intel's materials refer to 32 new instructions. The earlier SIMD instruction sets on the x86 platform, from oldest to newest, are MMX, 3DNow! (developed by AMD), SSE, 3DNow! Professional, SSE2, and SSE3.

New Instructions

In the table below, satsw(X) (read as 'saturate to signed word') takes a signed integer X, and converts it to -32768 if it's less than -32768, to +32767 if it's greater than 32767, and leaves it unchanged otherwise. As normal for the Intel architecture, bytes are 8 bits, words 16 bits, and dwords 32 bits; 'register' refers to an MMX or XMM vector register.
