"What makes the i.MX515 exciting, however, is the battery life
that it can potentially bring to its machines. According to
Freescale's statistics, the chip will have the capability to power
machines with up to 8 hours of battery life, with a display as
large as 8.9 inches. The company included many advanced power
management features such as a dedicated, hardware-based video
acceleration block, supposedly allowing for this long battery life
and significantly cooling things down. Freescale claims that there
is no need for heat sinks or fans with the processor."
