void Irqmp::acknowledged_irq	(	const uint32_t &	irq,
		const uint32_t &	cpu,
		const sc_time &	time
	)

Acknowledged Irq Callback

This Callback is called if the direct acknowledge way is used. It will clean the coressponding bit out of the pending and force registers.

Parameters

irq	The Interrupt to clean.
cpu	The CPU which acknowleged the Interrupt
time	Delay to the simulation time. Not used with this signal.

Here is the call graph for this function:

void Irqmp::clear_write ( )

Write to IR clear register

Triggers the cleaning of an interupt bit in the IR clear register. Will force a recalculation of a new interrupt.

Reset Callback

This function is called when the reset signal is triggert. The reset whill reset all registers and bring the IRQ controler in a valid state.

Parameters

value	Value of the reset signal the reset is active as long the signal is false. Therefore the reset is done on the transition from false to true.
time	Delay to the current simulation time. Is not used in this callback.

Reimplemented from CLKDevice.

void Irqmp::end_of_simulation ( )

SystemC end of simulation.

void Irqmp::force_write ( )

Write to the IR force register

If a write is done to the interrupt force register this function will recalculate the interrupt force settings and trigger a recalculation of the outputs.

Here is the call graph for this function:

void Irqmp::incomming_irq	(	const std::pair< uint32_t, bool > &	value,
		const sc_time &	time
	)

Incomming interrupts

This Callback is registert to the interrupt input signal. It will set the corresponding register bits and trigger a recalculation of the outputs.

Parameters

value	The value of the Interrupt. A value of false will be ignored due to the fact that interrupts can only be cleared in the interrupt controler.
irq	The interrupt line which is triggered.
time	Delay to the simulation time. Not used in this signal.
