An introduction to 64-bit computing and the PowerPC 970FX
A64-bit computing is well established on IBM's zSeries
and POWER-based pSeries systems. Nonetheless, with the introduction
of the PowerPC 970 processor family, 64-bit computing is now
available on the desktop, on value priced servers, and to
the embedded community. This paper will give an overview of
64-bit computing and discuss the advantages of a 64-bit operating
system environment.

IBM PowerPC 970FX power envelope and power management
The IBM PowerPC® 970FX microprocessor covers a large
frequency and power envelope through the use of dynamic frequency
and voltage scaling. This power-tuning allows one to quickly
change the frequency from full (f) to half (f/2) and quarter
(f/4) frequency at a system level, and for additional power
savings, one can apply the resulting voltage reduction. A
power envelope shows the complete range of frequency and power
available for the microprocessor. In addition to the full
frequency power-tuning capabilities, the power-saving modes
of doze, nap and deep nap reduce the power envelope, allowing
for a reduction of the average power consumption.

Introduction to embedded software development for the IBM
PowerPC 970FX processors
This article presents an overview of issues associated
with developing new and porting existing software to the IBM
PowerPC® 970FX processor. First, an overview of the PowerPC
64-bit architecture as implemented in the PowerPC 970FX processor
is presented. An introduction to the PowerPC 64-bit ELF Application
Binary Interface (ABI) is also presented followed by a brief
discussion of software development tools. The PowerPC 970FX
processor can execute PowerPC 32-bit (in 32-bit computation
mode) and PowerPC 64-bit (in 64-bit computation mode) programs.
This article presents issues associated with porting PowerPC
32-bit software and writing new software to execute in 64-bit
computation mode on the PowerPC 970FX processor. An overview
of tasks required to run existing PowerPC 32-bit software
in 32-bit computation mode is also presented.

The IBM PowerPC 970FX processor for embedded applications
There are many features that make the 64-bit IBM PowerPC®
970FX processor ideal for embedded deployments. A generic
64-bit processor brings an enhanced feature set compared with32-bit
processors to the table — but the 970FX brings even
more.

In search of a total system solution
The objective of the Avalanche Desktop Reference Management
Platform (DRMP) project is to investigate and validate the
promise of a complete open source software (OSS) solution
from kernel to plug-in. Through this project, Avalanche member
companies sought to document the value of lower IT costs through
collaboration in the implementation of a complete PowerPC
technology based OSS solution. Factors considered in the reduction
of total cost of ownership (TCO) included: hardware, support
and operational costs, and intangible costs, such as staff
familiarity with the software stack and the hardware. Finally,
as most senior managers, CFOs, CIOs, or COOs, are not aware
of the complexity and risks of OSS and application stack version
control, it is Avalanche's objective to enumerate and clarify
these issues.

Developing maximum performance, highly reliable, and extremely
secure embedded applications for the IBM PowerPC 970FX processor
Embedded software developers can now exploit the power of
the IBM PowerPC® 970FX processor. With the first embedded
software development tools for this processor, Green Hills
Software provides a complete, integrated development environment
(IDE) that takes advantage of features of the PowerPC 970FX
architecture, including the parallel execution units and AltiVec
vector processor. Green Hills Software’s MULTI IDE,
optimizing C and C++ compilers, JTAG probe, and INTEGRITY
Real-Time Operating System (RTOS) provide a complete solution
for the development, debugging and optimization of maximum-performance,
highly reliable, and extremely secure 970FX embedded applications.
