Class Speaker
java.lang.Object
jmce.sim.AbstractHardware
jmce.sim.AbstractPeripheral
jmce.sinclair.spectrum.Speaker
- All Implemented Interfaces:
- CycleListener, Hardware, MemoryWriteListener, Peripheral, SpectrumConstants
public class Speaker
- extends AbstractPeripheral
- implements MemoryWriteListener, CycleListener, SpectrumConstants
ZX spectrum Speaker emulation. Also manage the color of the border.
Very simple hardware means very time expensive emulation.

Speaker
public Speaker()
init
public void init(Hardware parent)
throws SIMException
- Description copied from interface:
Hardware
- Initialize the hardware. This method must be called before
any use of the interface. Only set ... / get ... method are
allowed to be called before the intialization.
- Specified by:
init
in interface Hardware
- Overrides:
init
in class AbstractHardware
- Parameters:
parent
- Parent of this hardware.
- Throws:
SIMException
writeMemory
public void writeMemory(Memory m,
int port,
int value,
int oldValue)
throws SIMException
- Description copied from interface:
MemoryWriteListener
- Called when a memory write event occours.
This method is called when a memory write operation occours
in the specified memory.
- Specified by:
writeMemory
in interface MemoryWriteListener
- Parameters:
m
- - Memory involved in the write operation.port
- - Address written.value
- - Value written.oldValue
- - Old value of this memory location.
- Throws:
SIMException
cycle
public void cycle(int n)
- Description copied from interface:
CycleListener
- Cycle listener. This type of listener is very time consuming
and must be used only when necessary because can have great
impact on the simulator performance.
- Specified by:
cycle
in interface CycleListener
- Parameters:
n
- - The number of microprocessor cycle elapsed from
the last call.- See Also:
CPU.addCycleListener(jmce.sim.CycleListener)
registerCPU
public void registerCPU(CPU _cpu)
throws SIMException
- Description copied from interface:
Peripheral
- Register a parent CPU for future reference.
- Specified by:
registerCPU
in interface Peripheral
- Overrides:
registerCPU
in class AbstractPeripheral
- Throws:
SIMException
toString
public java.lang.String toString()
- Overrides:
toString
in class AbstractHardware
