CPU Cache
Use this tab to enable or disable the CPU cache, Level 2 cache and to set
the Write Policy. Enabling the caches allows much faster system
performance.
Level 2 Cache Options and Write Policy are activated only
when the CPU cache is enabled. Disabling the CPU cache also disables
these features.
Write-back policy provides better system performance, because main
memory is accessed only when necessary to update the cache contents
with changes in main memory.
Write-through policy accesses main
memory every time data is handled by the processor. The write policy
option is used only for the CPU cache.
CPU Cache Options Enabled : Enables the CPU cache. (Default)
Disabled : Disables the CPU cache.
Level 2 Cache
Options Enabled : Enables the level 2 cache. (Default)
Disabled : Disables the level 2 cache.
Write Policy Write-back : Sets the write policy to write-
back. (Default)
Write-through: Sets the write policy to
write-through.
