►One of the challenges with
multicore is how to efficiently
utilize all the cores
►Consolidation of software running
on multichip onto a single
multicore device has inherit
difficulties:
• Each software base believes it owns the
full set of hardware resources
• Some resources (memory, interrupt
controllers, etc) will end up being shared
• Consolidated software has to be modified
to cooperate for shared hardware
resources
• Cooperation opens up the opportunity for
bugs in one software system to impact
another

Virtualization Challenges & 4080 Solution
►P4080 Supports true hardware
partitioning and virtualization:
• Each of the software systems and its
associated private hardware resources are
protected from other
• Hardware that is shared is managed so that
all software systems can use it without each
system having knowledge of the others
►Hardware support enables new
use models:
• With true isolation 3 rd party or customer
software can run on the system without
concerns of it impacting the rest of the
system
• Under utilized cores can be used to run
more than one operating system
• DRM and other secure data can be isolated
and protected in its own partition
