Technical Data
The MPC7455 and MPC7445 are implementations of the
PowerPC microprocessor family of reduced instruction set
computer (RISC) microprocessors. This document is primarily
concerned with the MPC7455; however, unless otherwise noted,
all information here also applies to the MPC7445. This document
describes pertinent electrical and physical characteristics of the
MPC7455. For functional characteristics of the processor, refer to
the
MPC7450 RISC Microprocessor Family User’s Manual
. To

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.
