class System
This class is an abstraction of an emulated system. Components are placed and interconnected here to create a functioning system.
Public Functions
-
System()
-
virtual ~System() = default
-
virtual void init()
Initialize a System to a power-on state. Default implementation just calls init on all components in m_components.
Note
For System developer: If there is any other operation except initializing all the components, you can override the method and implement the initialization yourself.
-
virtual void doClocks(unsigned int count) = 0
Proceed specified number of system clocks.
Note
For System developer: implement a reaction to a main clock signal. Normally whole emulation is driven by this function.
- Parameters
count – Number of clock to process.
-
virtual void doSteps(unsigned int count) = 0
Proceed specified number of CPU instructions.
Note
For System developer: You can for example proceed by single clocks until the CPU processes specified number of instructions. If there is no CPU, provide dummy method.
- Parameters
count – Number of instructions to process.
-
virtual void doFrames(unsigned int count) = 0
Proceed specified number of rendered frames.
Note
For System developer: If there is neither GPU or any definition of frame, provide dummy method.
- Parameters
count – Number of frames to process.
-
virtual void doRun(unsigned int updateFrequency) = 0
Run system in real-time.
Note
For System developer:
- Parameters
updateFrequency – Frequency in which the function is called to match the clock speed.
-
virtual void onRefresh()
Callback that is called on every new frame.
-
virtual std::vector<EmulatorWindow> getGUIs()
Get all the GUI elements created by the System and underlying Component(s).
- Returns
Vector of dockable windows.
-
virtual unsigned long getClockRate() const
Get main clock rate.
- Returns
Clock rate.
-
virtual size_t soundOutputCount() const
Get a count of sound outputs. Used to correctly construct nodes in Sound.h.
- Returns
Count of all sound outputs.
-
virtual const SoundSampleSources &getSampleSources() const
Get sample sources.
- Returns
Audio sample getters.
-
virtual std::vector<ImInputBinder::action_t> getInputs()
Get inputs of all components in the System.
- Returns
Required inputs.
-
virtual std::string getName() const final
Get system’s name.
