1 Overview

The MPC7447A is the fifth implementation of the

fourth-generation (G4) microprocessors from Freescale. The

MPC7447A implements the full PowerPC 32-bit

architecture and is targeted at networking and computing

systems applications. The MPC7447A consists of a

processor core and a 512-Kbyte L2.

Figure 1 shows a block diagram of the MPC7447A. The core

is a high-performance superscalar design supporting a

double-precision floating-point unit and a SIMD multimedia

unit. The memory storage subsystem supports the MPX bus

protocol and a subset of the 60x bus protocol to main

memory and other system resources.
