See Additional protocolson page 4-109.4.4.3 ParametersTable 4-8 lists the parameters set at the processor level for the ARMCortexA9UPCTcomponent.Table 4-8 ARMCortexA9UPCT parameters aParameter Description TypeAllowedvalueDefaultvalueCLUSTER_ID Processor cluster ID value. Integer 0-15 0device-accurate-tlbdcache-state_modelledicache-state_modelledSpecify whether all TLBsare modeled.Set whether D-cache hasstateful implementation.Set whether I-cache hasstateful implementation.Boolean true or false false bBoolean true or false falseBoolean true or false falsea. For the ARMCortexA9UP processor, the instance name for the processor consists of the normal instancename (in the provided examples, coretile.core) with a suffix of cpu0. In the example Cortex-A9 platform theinstance name is coretile.core.cpu0.b. Specifying false models enables modeling a different number of TLBs if this improves simulationperformance. The simulation is architecturally accurate, but not device accurate. Architectural accuracy isalmost always sufficient. Specify true if device accuracy is required.Table 4-9 provides a description of the processor configuration parameters for theARMCortexA9UPCT component.Table 4-9 ARMCortexA9UPCT individual processor parametersParameter Description TypeAllowedvalueDefaultvalueCFGEND Initialize to BE8 endianness.
