History

SSSE3 was first introduced with Intel processors based on the

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. Each instruction can act on 64-bit MMX or 128-bit XMM registers. Therefore, Intel's materials refer to 32 new instructions. They include: * Twelve instructions that perform horizontal addition or subtraction operations. * Six instructions that evaluate absolute values. * Two instructions that perform multiply-and-add operations and speed up the evaluation of dot products. * Two instructions that accelerate packed integer multiply operations and produce integer values with scaling. * Two instructions that perform a byte-wise, in-place shuffle according to the second shuffle control operand. * Six instructions that negate packed integers in the destination operand if the corresponding element in the source operand is negative. * Two instructions that align data from the composite of two operands.

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 is less than −32768, to +32767 if it is 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.
