4.02 CONFIGURING CACHE
The microprocessors have Internal Cache Memory available for faster execution of
applications.
Cache copies the most recently accessed data and places it in its fast Internal Cache
Memory. The CPU can then access this data at a very high speed. Since most program
executions are sequential and repetitive, the likelihood is great that the CPU will find data
already stored in Cache.
When the CPU retrieves data from Cache, a Cache hit occurs. On the other hand, when
the CPU must access data from System Memory, a Cache miss occurs .
Internal Cache Memory is enabled or disabled in the Advanced Setup screen of the
AMIBIOS Setup program. To run the AMIBIOS Setup program, boot-up your computer
and hit the DELETE key before or when the message - "Hit <DEL> if you want to run
SETUP" - appears near the top of the screen. Set the Internal Cache option in the
Advanced Setup screen to Enabled or Disabled.
