that automatically prefetches data and in-
structions from the memory into the Level
2 cache that are likely to be required in
the near future. This reduces the latency
associated with memory reads.
When enabled, the processor’s hardware
prefetcher will be enabled and allowed to
automatically prefetch data and code for
the processor.
When disabled, the processor’s hardware
prefetcher will be disabled.
