While many programs can obtain acceptable performance by simply letting the processor manage its own caching, programs with special requirements may obtain dramatically improved performance by giving the processor explicit instructions and manipulating the cache directly. More typically, boot firmware may need to flush and enable the cache. This article, an excerpt from an Application Note in the IBM Microelectronics Technical Library, discusses the basics on how you can manipulate the caches of the PowerPC 750GX and 750FX processors.
