Class BaseInstr

java.lang.Object
  hades.models.mips.instr.BaseInstr

All Implemented Interfaces:

Resetable

Direct Known Subclasses:

AluBaseInstr, AluImmBaseInstr, AluSpecialBaseInstr, BranchBaseInstr, BranchLinkBaseInstr, BreakInstr, CoprocInstr, IllegalInstr, JumpAndLinkInstr, JumpInstr, JumpRegAndLinkInstr, JumpRegInstr, LoadBaseInstr, MoveFromHiInstr, MoveFromLoInstr, MoveToHiInstr, MoveToLoInstr, NopInstr, StoreBaseInstr, SysCallInstr

public class BaseInstr

extends java.lang.Object

implements Resetable

This is the base class to all instructions implementing an interface usable for the Core. BaseInstr is like the NopInstr and does nothing real
