public MachineImpl(ModuleExecution module,
                   Face face)

Method Detail

step

public boolean step()

Advance the virtual machine, ensures the machine's state is valid after the instruction finishes.

Returns:

true if the current instruction changed (even if it's the same again).

onWriteCompleted

public void onWriteCompleted(Port port)

Inform the active instruction that a write operation was completed.

Instructions are expected to wait / loop until a write operation they initiated has been completed.

Parameters:

port - the port on which the write operation was completed.

getState

public MachineState getState()

Description copied from interface: Machine

Get the state of the machine, i.e. registers and program.

Specified by:

getState in interface Machine

Returns:

the state of the machine.

getInterface

public TargetInterface getInterface(Target target)

Description copied from interface: Machine

Get an interface that allows reading and writing to all valid Targets, including virtual ones. A TargetInterface is basically a Pipe wrapper and register wrapper in one.

Specified by:

getInterface in interface Machine

Parameters:

target - the target to get the interface for.

Returns:

the interface for the specified target.
