1 Overview

The MPC7455 is the third implementation of the fourth generation

(G4) microprocessors from Freescale. The MPC7455 implements

the full PowerPC 32-bit architecture and is targeted at networking

and computing systems applications. The MPC7455 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. The MPC7445 is identical to

the MPC7455 except it does not support the L3 cache interface.

Figure 1 shows a block diagram of the MPC7455.
