Hypervisor Micro-Kernel

The P3041’s e500mc cores offer a new embedded Hypervisor capability to address the need for a single

operating system performing coordination and access control functions, managing shared resources in an

efficient manner. The embedded Hypervisor provides the software layer needed to manage the operating

systems and supervisor-level applications as they access shared resources. Recognizing that each

developer’s system design may call for a different partitioning of resources, and involve different

combinations of OSes and RTOSes, Freescale and our ecosystem partners will provide reference

implementations of the embedded Hypervisor’s peripheral virtualization and access control which the

developer can modify to match unique system requirements.

4.3.3

DPAA Reference “Stacklets”

It is expected that some CPUs will be dedicated as datapath processors, working closely with the DPAA.

Freescale will provide reference protocol “stacklets,” optimizing performance critical regions of protocol

processing and their interaction with the DPAA hardware.

4.4

Top Level of the Pyramid: Application-Specific Enablement

This category includes 3rd-party stacks optimized for DPAA, RegEx, AV TCP, IPv4/6, IPsec/SSL.

Many of the expected applications for the P3041 involve network protocol processing. Partitioning

between control CPUs and datapath CPUs, and developing the protocol processing firmware which runs

on the datapath CPUs is an area for significant value added services for Freescale partners at the top level

of the enablement pyramid. OEMs wishing to engage with these partners can realize significant

“time-to-performance” advantages.
