Understanding 64-bit PowerPC architecture
Understanding 64-bit PowerPC architecture: " Each of the leading microprocessor manufacturers has announced the availability of one or more 64-bit desktop processors, but differences exist in architectural design, fabrication, support, and intended use of each processor. This article looks at the critical issues in a few of IBM's 64-bit POWER designs, covering 32-bit compatibility, power management, processor bus design, and the manufacturing process.

When people talk about 64-bit computing, it's not always clear what they mean. Most often, they mean some combination of register width, bus width, or address space. For the purposes of this article, it means a processor with 64-bit registers and 64-bit addressing."
