Intel® AVX

Leitbild

Der Bedarf an höherer Rechenleistung wächst in den verschiedensten Industriesegmenten stetig. Um dem steigenden Bedarf und den neuen Nutzungsmodellen Rechnung zu tragen, setzen wir mit den Intel® Advanced Vector Extensions (Intel® AVX) unsere Geschichte der Innovation fort.

Intel® AVX ist eine 256-Bit-Befehlssatzerweiterung Intel® SSE, speziell für fließkommaintensive Anwendungen. Sie wurde Anfang 2011 im Rahmen der Intel® Prozessor-Mikroarchitektur mit Codename Sandy Bridge vorgestellt und findet sich in allen möglichen Plattformen von Notebooks bis hin zu Servern. Intel AVX bietet Leistungsgewinne durch breitere Vektoren, eine neue erweiterbare Syntax und große Funktionsvielfalt. Dies bedeutet besseres Datenmanagement und Handling von Allzweckanwendungen wie Bild- und Audio-/Videoverarbeitung, wissenschaftliche Simulation, Finanzanalyse und 3D-Modellierung und -Analyse.

Visual Studio 2010 Built-in CPU Acceleration
By Asaf ShellyPosted Dezember 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 …

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
