Supplemental Streaming SIMD Extensions 3
SSSE3 ( S upplemental S treaming S IMD E xtensions 3 ) indicates the with Intel's Core architecture introduced enhancements to the SSE3 -Befehlssatzes. The terms Tejas New Instructions (TNI) or Merom New Instructions (MNI) are also used within the company. SSSE3 is often incorrectly referred to as SSE4 , but SSE4 is a completely different instruction set extension.
New orders
SSSE3 extends the SSE3 instruction set by 16 new instructions. Since these can be applied to both 64-bit MMX registers and 128-bit SSE registers, Intel states that there are 32 commands.
- psignw, psignd, psignb
- pshufb
- pmulhrsw, pmaddubsw
- phsubw, phsubsw, phsubd
- phaddw, phaddsw, phaddd
- palignr
- pabsw, pabsd, pabsb
SSSE3 was presented as part of the Intel Core microarchitecture and was integrated for the first time in the processor cores Merom ( notebook ), Allendale / Conroe ( desktop ) and Woodcrest ( server ).
