What is a SSE4 2 instruction set?

What is a SSE4 2 instruction set?

SSE4. 2, a second subset consisting of the seven remaining instructions, is first available in the Nehalem-based Intel® Core™ i7 Processor. Intel credits feedback from developers in the development of the instruction set.

Do I have SSE4 2?

If you are unsure about your particular computer, you can determine SSE2 support by: Windows: A free download, CPU-Z, is available from CPUID that will indicate if SSE2 is present on your system or not. Linux: From a terminal, run “cat /proc/cpuinfo”. “sse2” will be listed as one of the “flags” if SSE2 is available.

Are there any instruction sets that support SSE4?

As you can see from the chart in the table above, after SSE3, the library supports the SSSE3, SSE4.1, SSE4.2, AES-NI and AVX instruction sets. There are also several good articles in Wikipedia describing the differences between the various SIMD instructions sets available today.

How to determine if a processor supports SSE 4.1?

In this application note, a set of code sequences is shown to determine if the processor being queried supports the SSE 4.1 and SSE 4.2 instruction sets . The code in this application note was designed to run on Intel 64 Architecture processors running a 32 bit or 64 bit Windows or Linux Operating System.

How can I detect the presence of SSE 4.1?

Using CPUID to Detect the presence of SSE 4.1 and SSE 4.2 Instruction… Using CPUID to Detect the presence of SSE 4.1 and SSE 4.2 Instruction Sets [PDF | 132kb]

When did SSE2 and SSE3 come out?

• MMX (Multimedia Extension) was introduced in 1996 (Pentium with MMX and Pentium II). • SSE (Streaming SIMD Extension) was introduced in 1999 with Pentium III. • SSE2 was introduced with Pentium 4 in 2001. • SSE3 was introduced in 2004 with Pentium 4 supporting hyper-threading technology. SSE3 adds 13 more instructions. 10/11/2008 4 7 MMX
