Since the world likes open standards, which anyone can use and build upon without fear of reprisals or need for licensing fees, Dell decided to attend the Open Compute Summit in Santa Clara, California. Advanced Micro Devices and Intel both tried to steal the show, with their Open 3.0 and Silicon Photonics technologies.
The time has come - there is ARM 64-bit architecture right behind a corner. In this talk I will present how OpenEmbedded was used to build root file system for fast models simulating not-yet-existing hardware. Presentation is targeted at developers interested in cross compilation, handling new architectures in existing projects.
This is a question I have faced several times during my career in enterprise software development. Every once in awhile I’ve had to hand out recommendations for configuring a specific new environment. And more often than not, part of the question at hand was related to “Should I use a 32- or a 64-bit JVM”. To be honest, in the beginning I just flipped the coin. Instead of giving a reasoned answer. (Sorry, bros!) But by now I have gathered some more insight on this and thought to share it with you.
The inserting and extracting instructions are mostly from SSE 4.1 (the PINSRW and PEXTRW are from SSE2). They can move any element from an SSE register to an x86 register (extract) or move an x86 register's value to any element in an SSE register.
In this tutorial we're looking at comparison instructions that compare SSE registers but set the x86 flags register. These allow us to compare the lowest singles or doubles in SSE registers and then jump using the x86 conditional jumps or perform conditional moves.
Today we'll look at three instructions, MOVMSKPS, MOVMSKPD and PMOVMSKB. They move the signs of elements in SSE registers into an x86 register. They are especially useful after the SIMD comparison instructions.
All of the disassembly I'll show you is from Visual Studio 2012 Express. Comments I make about MSVC are referring to that version as well. If you're following along at home with 2010, you won't see any differences with the compilation of my example code.
This pure C# program parses the almost-ML64-compatible x64 assembly-language listing generated by Microsoft Visual C++ 2010 (when configured to produce x64 assembly-language listing files), and forms corresponding x64 CPU byte code, and executes that byte code in a new thread. This dynamic generation and execution of x64 CPU byte code is similar to what the .NET Common Language Runtime (CLR) does during the Just-In-Time (JIT) compiling process and subsequent execution.
Today's tute we'll explore how some of the facets of Object Oriented C++ work. It's nothing like it seems. The information in this tutorial may not be immediately useful but it's actually very handy. There is a concept called AoS (Array of Structures) versus SoA (Structure of Arrays), to get maximum speed from our SIMD code sometimes we need the data organized in a special way, this type of knowledge (apart from being interesting) is invaluable when we need complete control over these types of things.
Linaro Connect (LCE 12) will take place at the Bella Center in Copenhagen Denmark on 29 Oct to 2 Nov 2012. Registration for this event is now open and those who will be attending are encouraged to register earlier. In addition to the regular track sessions—Android, Graphics and multimedia, Kernel, Platform (Ubuntu and generic Linux), Power, QA/Infrastructure, Tools, Training and Validation/LAVA—this Linaro Connect event in Copenhagen will host three (3) mini summits.
Early prototype 64-bit ARM servers could be available for testing purposes by the end of this year or possibly at the latest by the middle of next year, ARM said on Monday. ARM will try to make inexpensive 64-bit server hardware available by working with partner Applied Micro Circuits, which has licensed the chip designer's 64-bit ARMv8 architecture, said Ian Ferguson, director of server systems and ecosystem at ARM.
Join Experts Exchange and systems management and admin virtuoso Darwin on September 13th from 11am- 12pm PDT for a Windows 7 and 64-bit app webinar. Darwin will present an overview of WOW64 design and outline problem areas for managing application files and registry settings. The session includes walkthroughs using scripting and shell extension toolkit that makes production script adaptation effortless for shell scripting. In this hour-long presentation, Darwin will discuss:
Last October, ARM disclosed technical details about its new v8 architecture - which is the first to include a 64-bit instruction set. The next-gen architecture is expected to significantly extend the reach of ARM processors in the lucrative server market, which is currently dominated by x86 chips.
