In this tute we'll get to coding some little ASM algorithms. First we have to look at how parameters will be passed from C++.

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):

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.

Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. It is being used in planetarium projectors. Just set your coordinates and go.

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.

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.

With people eyeing new Windows 8 and Mountain Lion powered computers, the question of how much RAM a modern system needs is hitting my inbox with increased frequency. Here is my definitive guide to how much RAM you need.

A short video showing how to import a virtual machine/appliance in virtual box. Also shows what the errors you receive if virtualization is not enabled in your computers bios

This tutorial shows how to install windows 8 64-bit from the install cd onto a samsung 7 series laptop. 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.

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.

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.

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

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.
