PC7457/47

Description

This document is primarily concerned with the PowerPC^™PC7457; however, unless

otherwise noted, all information here also applies to the PC7447. The PC7457 and

PC7447 are implementations of the PowerPC microprocessor family of reduced

instruction set computer (RISC) microprocessors. This document describes pertinent

electrical and physical characteristics of the PC7457.

Preliminary

Specification

α-site

The PC7457 is the fourth implementation of the fourth generation (G4) microproces-

sors from Motorola. The PC7457 implements the full PowerPC 32-bit architecture and

is targeted at networking and computing systems applications. The PC7457 consists

of a processor core, a 512 Kbyte L2, and an internal L3 tag and controller which sup-

port a glueless backside L3 cache through a dedicated high-bandwidth interface. The

PC7447 is identical to the PC7457 except it does not support the L3 cache interface.

The core is a high-performance superscalar design supporting a double-precision

floating-point unit and a SIMD multimedia unit. The memory storage subsystem sup-

ports the MPX bus interface to main memory and other system resources. The L3

interface supports 1, 2, or 4M bytes of external SRAM for L3 cache and/or private

memory data. For systems implementing 4M bytes of SRAM, a maximum of 2M bytes

may be used as cache; the remaining 2M bytes must be private memory.

Note that the PC7457 is a footprint-compatible, drop-in replacement in a PC7455

application if the core power supply is 1.3V.
