4.3.2 PowerPC Processing Cores
The T2081/T1042 contain four high-performance PowerPC processing cores. Each
core includes:
•
32 KB Level 1 instruction and data caches incorporating data and tag parity
protection
•
Physical addressing: 40-bit (T2081)/36-bit (T1042)
•
Double Precision Floating Point Unit
•
MMU with embedded Hypervisor privilege level

Depending on the application, it is possible for software to dynamically configure
processors to run at lower clock frequencies to minimize power.
4.3.3 Trust Architecture
The T2081/T1042 processors contain a set of hardware features that support a trusted
boot environment where only trusted code may be executed and hardware features
that could be used to compromise security are disabled. The implementation of this
architecture is fully described in the Freescale white paper “An Introduction to the
QorIQ Platform’s Trust Architecture”.
The PPC11A provides the ability to program fuses within the processor to configure
security keys, access to which is controlled by the security state of the processor.
If you wish to use this feature of the platform, contact Abaco for more information.
