MPC7450 RISC Microprocessor Hardware Specifications
Overview
1.1 Overview
The MPC7450 is the third implementation of the fourth generation (G4) of PowerPC microprocessors from
Motorola. The MPC7450 implements the full PowerPC 32-bit architecture and is targeted at networking and
computing systems applications. The MPC7450 consists of a processor core, a 256-Kbyte L2, and an
internal L3 tag and controller which support a glueless backside L3 cache through a dedicated
high-bandwidth interface.
Figure 1 shows a block diagram of the MPC7450. The core is a high-performance PowerPC 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. The L3 interface
supports 1 or 2 Mbytes of external SRAM for L3 cache data.
