Build a GNU cross compiler for PowerPC

IBM 6 Comments
Learn how to build a GNU cross compiler for PowerPC code development by downloading the PowerPC 750GX/FX evaluation kit (free reg. req.). The source code illustrates how to initialize and utilize various features of the processor--memory management unit, interrupts, and debugging features. The board schematics provide an example of how to connect the processor to a system controller (bridge) chip and other components in the system.

IBM Releases Object Rexx as Open Source

  Submitted by Esther Schindler IBM 21 Comments
IBM's programming and scripting language, REXX, may have achieved a unique range of supported platforms, with success on everything from the Commodore Amiga to OS/2 to IBM mainframes. Over the years, REXX gained object-oriented features, and turned into Object Rexx, with programming interfaces to DB2, C, and C++ applications. A few weeks ago, IBM quietly released Object Rexx to the open source community. RexxLA — the REXX Language Association — targeting the first release of Open Object REXX for early 2005.

G6: More POWER on the way?

IBM 34 Comments
Last year IBM introduced a cut-down POWER4 CPU called the PowerPC 970 and Apple promptly put it into their PowerMac line. IBM are not standing still; the POWER5 is out and rumours have long hinted at a successor to the 970 being in development. What should we expect?

Why open Mac bootware may be more practical

IBM 4 Comments
Open Firmware is software that is used after powering a machine to bring the operating system online (most visibly on PowerPC and SPARC systems), all modern Macintosh systems use it. This article looks at the Open Firmware spec, traces its history as a standard, examines how it works and some of its components, and discusses the benefits it offers. The best way to learn more about OF is to practice, to get a Mac, hold down command-option-O-F when you turn it on, and just start typing.

Is there a ClearCase to move to UCM?

IBM 2 Comments
Are you thinking of moving from base Rational ClearCase to Unified Change Management (UCM)? Many organizations find it difficult to use ClearCase out of the box. UCM was an effort to identify the most common elements of ClearCase use models, and to create objects and methods that make the application more effective. This article shares some points that you may want to consider when making the decision to move to UCM.

Tips on porting Intel apps to 32 bit and 64 bit Linux on POWER

IBM 19 Comments
This article reviews tips for porting 32-bit software from Linux IA32 to Linux PowerPC. Linux PowerPC also provides a platform for the development and deployment of 32 bit applications that would benefit from a 64 bit environment. This article shares the best practices for porting Intel applications to 64 bit Linux on power. In both casses, PowerPC derived chips offers industry leading performance and provides a world class hardware platform for the deployment and migration of Intel 32 bit and 64 bit apps to the Linux PowerPC environment.
