1 Overview

The MPC7448 is the sixth implementation of fourth-

generation (G4) microprocessors from Freescale. The

MPC7448, built on Power Architecture™ technology,

implements the PowerPC™ instruction set architecture

version 1.0 and is targeted at networking and computing

systems applications. The MPC7448 consists of a processor

core and a 1-Mbyte L2.

Figure 1 shows a block diagram of the MPC7448. 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.
