64-bit Technology News

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.

This is a demo of how to convert a 32bit aggr to a 64bit aggr in NetApps Data Ontap system.

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.

I've been using the ADN utilities, which include some ActiveX controls. Now I'm migrating my project to x64 OS and have downloaded the 64 bit version of the controls, however I cannot place them on my Form in Visual Studio.

TSMC and ARM announced today that they will extend their existing collaboration beyond 20nm fabrication to deliver ARM-based processors that use FinFET transistors.

We'll detour (sort of, the final demo uses SSE2 and 3) from SSE instructions and examine structures today. Structures in ASM are almost the same as their C++ counterparts but there's a few little tricks to look at before C++ and ASM will play together.

The ARM v8 architecture has already been acknowledged as the great accomplishment that will pull the architecture out of the confines of the mobile market, and now we know who will help ARM Holding the most: TSMC.

The conversion instructions cast and convert data from integers to floats and copy from SSE to x86 or MMX registers. There's many of them so we'll only look at a couple in examples. They are mostly pretty basic. We'll also look at how to set the rounding function in MXCSR and what C++ does when we cast floats.
