Abstract; Overview; Processor Version Register (Pvr) - IBM POWERPC 970MP Application Note

Preliminary

1. Abstract

This preliminary application note describes the differences between the PowerPC
and PowerPC 970MP microprocessor. The primary objective of the PowerPC 970FX remap to the 970MP is
to achieve a high frequency dual core processor. The design changes include a 1MB L2 cache per core,
support for higher bus speeds, power management improvements, and errata fixes.

2. Overview

The IBM 970MP RISC Microprocessor is a dual-core, 64-bit implementation of the IBM PowerPC
reduced instruction set computer (RISC) microprocessors that are based on the PowerPC Architecture. This
dual microprocessor, also called the 970MP, includes a Vector/SIMD facility in each core which supports
high-bandwidth data processing and compute-intensive operations. The 970MP is designed to support
multiple system organizations, including desktop and low-end server applications, up through 4-way SMP
configurations.
The differences between the PowerPC 970FX and 970MP designs are described in the following sections:
• Process Version Register
• General Parameters
• Design Enhancements
• System Design Information
• Timings
• Package

3. Processor Version Register (PVR)

The PowerPC 970FX and 970MP have the following PVR values for the respective design revision levels.
