Detailed Description

Minor contains all the definitions within the MinorCPU apart from the CPU class itself

Typedef Documentation

◆ FUPipelineBase

typedef SelfStallingPipeline<QueuedInst, ReportTraitsAdaptor<QueuedInst> > Minor::FUPipelineBase

Functional units have pipelines which stall when an inst gets to their ends allowing Execute::commit to pick up timing-completed insts when it feels like it.

Definition at line 219 of file func_unit.hh.

◆ MinorDynInstPtr

typedef RefCountingPtr<MinorDynInst> Minor::MinorDynInstPtr

MinorDynInsts are currently reference counted.

Definition at line 61 of file dyn_inst.hh.

◆ MinorThread

typedef SimpleThread Minor::MinorThread

Minor will use the SimpleThread state for now.

Definition at line 58 of file cpu.hh.
