  • Linux x64 Assembly Tutorial 2: Bits, Bytes and Registers

    Start64!Today we'll look at integer data types, bits, bytes, words and all that. We'll also look at the general purpose register set. I didn't really mention it in the tute but the suffixes for AT&T that match the register sizes are (using RAX as the example register):

  • x64 Assembly and C++ Tutorial 61: AVX Negate 128bpp Image

    Start64!Big thank you to all who've sent in Imogen plugins, they're excellent, Keep em' coming folks! This tutorial we'll look at some of the 256 bit SIMD, AVX instructions briefly then code the negate algorithm from last tute using them.

  • x64 Assembly and C++ Tutorial 60: C++ Negate 128bpp Image

    Start64!In this tute we'll look at coding a C++ algorithm to negate a 128bpp image. This will be a benchmark to beat for the ASM versions we'll code next. Most of this tutorial is about interacting with .Net 4.5 from native code.

  • Linux x64 Assembly Tutorial 2: Intro to ASM and AT&T Syntax

    Start64!In this tutorial we're looking a little at what an Assembly language is and why anybody would bother with it. I've also decided to include information about AT&T syntax in this series, so at the end I've coded the same example as last time only I've used the GAS assembler with AT&T syntax.

I describe how then install drivers, office preview, and then create a refresh image. It is my recommendation when running windows 8 to use a microsoft outlook email address. It works better with all microsoft products and is becoming better than gmail. If you don't have one, make one.

  • Linux x64 Assembly Tutorial 1: Getting a Value from NASM into G++

    Start64!This tutorial is a remake of the first Windows C++ and ASM tutorial only I'm using Ubuntu. I'm in Ubuntu 12.10 here with G++ and NASM. For a text editor I'm a big fan of the ultra minimalist Nano. We'll probably have to shift to something a little heavier weight eventually.

  • x64 Assembly and C++ Tutorial 57: SSE Inserting and Extracting Instructions

    Start64!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.

  • x64 Assembly and C++ Tutorial 56: SSE Comparisons that Set rFlags

    Start64!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.

  • How to: Install Windows 8 Professional 64-bit

    Start64!I install Windows 8 Professional 64-bit and go over some of the features including the new Windows Update.

  • x64 Assembly and C++ Tutorial 54: SSE Moving Sign Masks

    Start64!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.

  • In-depth: Windows x64 ABI: Stack frames

    Start64!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.
