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.
