Motorola and Apple computer have been using the MPC7400 PowerPC
microprocessor in their G4 computers. This is a high- performance,
low- power, 32- bit implementation of the
PowerPC Reduced Instruction Set Computer (RISC). This is an architecture
combined with a full 128- bit including Motorola's AltiVec
technology instruction set, which allows for a creating of a
high- performance RISC microprocessor ideal for leading- edge
computing like the Apple, and signal processing functions.
The MPC7400 microprocessors offer a single- cycle
double- precision floating- point performance.It provides a
symmetric multiprocessing (SMP) capabilities. Also supports
up to 2MB of backside L2 cache. The full potential of the MPC7400
achieved through use of the OS X software licensed from Apple.
The instruction provided by the OS X takes the full potential
to provide instruction to operate the AltiVec technology.
The MPC7400 is called a super scalar microprocessor which
feature a high-frequency super scalar PowerPC core, capable of
issuing three instructions per clock cycle (two instructions
+ branch) into seven independent execution units
Motorola's MPC7400 and 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. No two chip set
The MPC7400 is able to meet the demands of networking such
those found with multichannel modems, echo cancellation equipment,
and base station processing. This enables a faster, and more
secure encryption methods as well.
The MPC7400 microprocessors uses a low - power 1.8 - volt
design with three power - saving user - programmable. Modes:
include sleep step down which progressively reduce the power
drawn by the processor and full power.
Assisted from software the MPC7400 provides a thermal instruction
cache throttling for thermal management.
Suggested applications for the
- Networking and telecommunications infrastructure
- High- performance computing (scientific, medical, etc.)
- Desktop and portable computing presently inside every G4
