Detailed Description

Implementation specific struct that defines several key types to the CPU, the stages within the CPU, the time buffers, and the DynInst.

The struct defines the ISA, the CPU policy, the specific DynInst, the specific O3CPU, and all of the structs from the time buffers to do communication. This is one of the key things that must be defined for each hardware specific CPU implementation.

Member Typedef Documentation

CPUPol

typedef SimpleCPUPolicy<O3CPUImpl> O3CPUImpl::CPUPol

The CPU policy to be used, which defines all of the CPU stages.

Definition at line 56 of file impl.hh.

CPUType

typedef O3CPU O3CPUImpl::CPUType

Same typedef, but for CPUType.

BaseDynInst may not always use an O3 CPU, so it's clearer to call it CPUType instead in that case.

Definition at line 74 of file impl.hh.

DynInst

typedef BaseO3DynInst<O3CPUImpl> O3CPUImpl::DynInst

The DynInst type to be used.

Definition at line 59 of file impl.hh.

DynInstConstPtr

typedef RefCountingPtr<const DynInst> O3CPUImpl::DynInstConstPtr

Definition at line 65 of file impl.hh.

DynInstPtr

typedef RefCountingPtr<DynInst> O3CPUImpl::DynInstPtr

The refcounted DynInst pointer to be used.

In most cases this is what should be used, and not DynInst *.

Definition at line 64 of file impl.hh.

MachInst

typedef TheISA::MachInst O3CPUImpl::MachInst

The type of MachInst.

Definition at line 53 of file impl.hh.

O3CPU

typedef FullO3CPU<O3CPUImpl> O3CPUImpl::O3CPU

The O3CPU type to be used.

Definition at line 68 of file impl.hh.
