Description

The MPC7441 is the third implementation of the fourth generation (G4) microprocessors from Motorola. It implements the full PowerPC 32-bit architecture and is targeted at networking and computing systems applications. The MPC7441 consists of a processor core and a 256-Kbyte L2.

Figure 1 shows a block diagram of the MPC7441. 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 interface to main memory and other system resources.
