DCU Streamer Prefetch
There are two distinct hardware prefetchers on aTCA-6200. Data Cache Unit (DCU) streamer
prefetcher and Data Cache Unit (DCU) IP-prefetcher. DCU streamer prefetchers detect
multiple reads to a single cache line in a certain period of time and choose to load the
following cache line to the L1 data caches.
This option allows user to enable or disable DCU streamer Prefetcher.
DCU IP Prefetcher
DCU IP Prefetcher looks for sequential load history to determine whether to prefetch the
data to the L1 caches.
This option allows user to enable or disable DCU IP Prefetcher.
Intel Virtualization
Intel Virtualization Technology consists of components that support virtualization of
platforms based on Intel processors, thereby enabling the running of multiple operating
systems and applications in independent partitions. Each partition behaves like a virtual
machine (VM) and provides isolation and protection across partitions.
Intel VT requires the use of a processor with Intel VT support. Additionally, a third-party
VMM may also be required. Options: Enabled/Disabled.
6.3.2.2 CPU Power Management Configuration
CPU Power Management configuration opens some item for adjusting the load or timing to
reduce the power consumption. User can go to this setup page to configure the best setting
for the whole system.
