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.
