Class GenInterpreter

java.lang.Object
  avrora.sim.BaseInterpreter
      avrora.sim.GenInterpreter

All Implemented Interfaces:

InstrVisitor

Direct Known Subclasses:

DBBCInterpreter

public class GenInterpreter

extends BaseInterpreter

implements InstrVisitor

The GenInterpreter class is largely generated from the instruction specification. The framework around the generated code (utilities) has been written by hand, but most of the code for each instruction is generated. Therefore it is not recommended to edit this code extensively.

Nested Class Summary

static class

GenInterpreter.Factory The Factory() class implements an interpreter factory that can create a new interpreter for a new simulator instance with the given program.

Constructor Detail

GenInterpreter

protected GenInterpreter(Simulator s,
                         Program p,
                         MicrocontrollerProperties pr)

The constructor for the Interpreter class builds the internal data structures needed to store the complete state of the machine, including registers, IO registers, the SRAM, and the flash. All IO registers are initialized to be instances of RWIOReg. Reserved and special IO registers must be inserted by the getIOReg() and writeIOReg() methods.

Parameters:

s - The simulator attached to this interpreter

p - the program to construct the state for

pr - the properties of the microcontroller being simulated

Method Detail

runLoop

protected void runLoop()

Specified by:

runLoop in class BaseInterpreter

step

public int step()

Description copied from class: BaseInterpreter

The step() method steps this node forward one instruction or one clock cycle. The node may execute an instruction, execute events, wake from sleep, take an interrupt, etc. In the case of multi-cycle instructions, the node will execute until the end of the instruction. The number of cycles consumed is returned by this method.

Specified by:

step in class BaseInterpreter

Returns:

the number of cycles consumed in executing one instruction or waking from an interrupt, etc
