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.
