PC7400 PowerPC™ Microprocessor

Fact Sheet

The PC7400 PowerPC microprocessor is a high-performance, low-power, 32-bit implementation of the PowerPC Reduced

Instruction Set Computer (RISC) architecture combined with a full 128-bit implementation of Motorola’s AltiVec

technology instruction set, creating a high-performance RISC microprocessor ideal for leading-edge computing, control, and

signal processing functions. The MPC7400 supports the high-bandwidth MPX bus with minimized signal setup times and

reduced idle cycles to increase maximum operating frequency to over 100 MHz, increased address bus bandwidth, increased

data bus bandwidth, and more enhancements. To maintain backward compatibility for existing applications, thePC7400 also

supports the 60x bus protocol. MPC7400 microprocessors offer single-cycle double-precession floating-point performance,

provide full symmetric multiprocessing, (SMP) capabilities, and support up to 2MB of backside L2 cache. While the PC7400

is software-compatible with existing applications for PowerPC 603e

, PowerPC 740

, and PowerPC750

microprocessors, to utilize the full potential of this AltiVec technology-enabled device, some instruction changes in existing

source code are required to interface with the vector execution unit.

AltiVec Technology

AltiVec Technology expands the capabilities of PowerPC microprocessors by providing leading-edge, general-purpose

processing performance while concurrently addressing high-bandwidth data processing and algorithmic-intensive

computations in a single-chip solution. AltiVec technology:

Meets the computational demands of networking infrastructure such as multichannel modems, echo cancellation equipment,

and basestation processing.

Enables faster, more secure encryption methods optimized for the SIMD processing model

Provides compelling performance for multimedia-oriented desktop computers, desktop publishing, and digital video

processing.

Enables real-time processing of the most demanding data streams (MPEG-2 encode, continuous speech recognition, real-time

thigh-resolution 3D graphics, etc…)
