Assembly language for Power Architecture, Part 1: Programming concepts and beginning PowerPC instructions
The POWER5 processor is a 64-bit workhorse used in a variety of settings. Starting with this introduction to assembly language concepts and the PowerPC instruction set, this series of articles introduces assembly language in general and specifically assembly language programming for the POWER5. 		03 Oct 2006  
 
Assembly language for Power Architecture, Part 4: Function calls and the PowerPC 64-bit ABI
The ABI, or Application Binary Interface, is the set of conventions that allow programs written in different languages or compiled by different compilers to call each other's functions. This article, the last in a four-part series, discusses the PowerPC ABI for 64-bit ELF (UNIX-like) systems and how to write and call functions using it. Knowing in detail how the 64-bit PowerPC ABI works will help you write 64-bit programs for the POWER5 and other PowerPC-based processors more effectively, whether you program in assembly language or not. There is also a 32-bit ABI that is not covered in this article. 		28 Feb 2007  
 
Assembly language for Power Architecture, Part 3: Programming with the PowerPC branch processor
The last two articles discussed the outline of how programs on the POWER5 processor work using the 64-bit PowerPC instruction set, how the PowerPC instruction set addresses memory, and how to do position-independent code. This article focuses on the very powerful condition and branch instructions available in the PowerPC instruction set. 		17 Jan 2007  
 
Assembly language for Power Architecture, Part 2: The art of loading and storing on PowerPC
The previous article in this series introduced assembly language programming using the 64-bit PowerPC instruction set on POWER5 and other processors that use these instructions. This article drills down and discusses the specifics of 64-bit PowerPC assembly language programming on Linux and UNIX-like operating systems, focusing on data access methods and position-independent code. 		29 Nov 2006
