A developer’s guide to the PowerPC architecture

Mar 31, 2004 — by LinuxDevices Staff — from the LinuxDevices Archive — views

IBM's developerWorks has published an overview of the PowerPC's architecture and application-level programming model that could be of interest to embedded developers doing kernel work on PPC-Linux systems.

The detailed, technical article begins with a discussion of PowerPC architecture, common to all chip branches and comprised of:

  • Book I. User instruction set architecture
  • Book II. Virtual environment architecture
  • Book III. Operating environment architecture

The article then delves into the programming model, discussing:

  • Application-level registers
  • Application-level instruction set
  • Timers
  • Maintaining code compatibility

Both PowerPC AS and PowerPC Book E are addressed.
