Abstract:
This paper discusses the use of the CPU cache when the processor is
being used to manipulate stream data, in particular isochronous media
such as as video. The principal idea is to enable data to avoid main
memory and flow directly into a portion of the cache. When used with a
``cache aware'' operating system this method is shown to provide a
rich support environment for multimedia manipulation. Experiments to
demonstrate this have been performed on a workstation based on the
Desk Area Network architecture, and results are presented.
