Intel® AVX

Declaración de visión

La necesidad de un mayor desempeño computacional sigue creciendo en todos los segmentos de la industria. Para la compatibilidad ante la creciente demanda y los modelos de uso en evolución, continuamos nuestra historia de innovación con  Intel® Advanced Vector Extensions (Intel® AVX).

Intel® AVX es una nueva extensión del conjunto de instrucciones de 256 bits para Intel® SSE y se diseñó para aplicaciones que usan Floating Point (FP - Punto flotante) de manera intensa. Se lanzó al mercado a principios del año 2011 como parte de la familia de procesadores de la microarquitectura Intel ®, con el nombre de código 'Sandy Bridge', y se encuentra en plataformas que abarcan desde notebooks a servidores. Intel AVX mejora el desempeño gracias a vectores más anchos, nueva sintaxis ampliable y funcionalidad enriquecida. Esto resulta en una mejor administración de los datos y las aplicaciones para fines generales como el procesamiento de imágenes, sonido/video, simulaciones científicas, análisis financieros, y modelos y análisis tridimensionales.

Jeff's Notebook: 3D Vector Normalization Using 256-Bit Intel® Advanced Vector Extensions (Intel® AVX)
By Jeff Kataoka (Intel)Posted Febrero 11th 20110
With the launch of our New Second Generation Intel® Core processor, there has been a lot of interested in the Intel® Advanced Vector Extensions (Intel® AVX). I decided to investigate more on how application developers targeting the Second Generation Intel core processor for their application might ...
Visual Studio 2010 Built-in CPU Acceleration
By Asaf ShellyPosted Diciembre 20th 20105
Writing the sample code for this post I was amazed myself to see how simple it was to reach over 20 times performance improvement with so little effort.    The motivation is a very heavy video processing algorithm created for HD TV. This means hi-resolution which means many pixels to compute and ...

8086/8088 core9
Hi,  I am a grad student in EE. I am looking for 8088/8086 core for my project. Project is to design a bus monitor which can interface with either 8088/8086. I searched on opencore.org but could not find. I am looking for one which has all pins exposed - ALE, RD, WR, DEN, Addr/Data etc.  Please can ...

with _mm256 instruction, does it matter to use -xAVX to compiler?12
I wrote some AVX instructions like :     __m256 x0 = _mm256_load_ps(f);    __m256 y0 = _mm256_load_ps(f+8);    __m256 z0 = _mm256_add_ps(x0, y0);    _mm256_store_ps( s, z0); When I compiler this, does it matter whether I use -xAVX compiler option or not? I am using icpc 2013 on Linux

64-bit bug in Visual C++? mov R8d,imm not completley defined12
The Intel  documentation does not specify wether  mov R8d , -1  will also zero the high dword of R8, or leave it intact.  The Microsoft Visual C++  (2010)  translate the C line  a = myfunc(par1, par2, 3) ; into          mov RCX, par1 ; mov RDX, par2 ;   mov R8b, 3 ;    call myfunc;    move qword ...

Haswell RCPPS/RSQRTPS implementation16
Hi, I work on code which targets AVX2 + FMA3 and depends on the accuracy of VRCPPS/VRSQRTPS. Should I expect the implementation of these instructions on Haswell to be the same as on Ivy Bridge? Regards, Marat
