Processor Components
4.4.8 Performance
The ARMCortexA9UPCT component provides high performance in all areas except VFP and
NEON instruction set execution which currently does not use code translation technology.
4.4.9 Library dependencies
The ARMCortexA9UPCT component has no dependencies on external libraries.
4.4.10 Differences between the CT model and RTL implementations
The ARMCortexA9UPCT component differs from the corresponding revision of the ARM
Cortex-A9 RTL implementation in the following ways:
• The RR bit in the SCTLR is ignored.
• The Power Control Register in the system control coprocessor is implemented but writing
to it does not change the behavior of the model.
• The model cannot be configured with a 128-entry TLB.
