Internal Cache
Cache memory is additional memory that is much faster than conventional
DRAM (system memory). When the CPU requests data, the system transfers
the requested data from the main DRAM into cache memory, for even faster
access by the CPU. The setting controls the internal cache (also known as L1
or level 1 cache). Setting options:
Disabled, WriteBack, Write Thru. WriteBack
&
WriteThru
refer to the cache’s write policy, which determines how it handles
writes to memory locations that are currently being held in cache. The
WriteBack
cache policy will produce the best performance.
