Detailed Description

This class resets resettable processes in the same delta cycle.

rc_process_reset is a reset channel that implements rc_reset_channel_if. In constrast to normal reset signals it is attached to process by method reset_is(). Another difference is that it does not possess an active level. Instead rc_process_reset only provides a trigger() method that can be called to trigger a single discrete reset and, thus, get_current_level() will always return false. The reset will occur in same delta cycle as the trigger call.

Example:

 rc_process_reset preset; // declaration at class scope
 [...]
 RC_THREAD(proc);  // creation of the thread process
 reset_is(preset); // proc is reset by preset now
 [...]
 preset.trigger(); // trigger the reset (e.g. from another process)

Member Function Documentation

void trigger

(

)

[virtual]

Trigger a reset on this object.

Definition at line 645 of file rc_process_support.cpp.

void register_process_control	(	rc_process_control &	pctrl,
		bool	active_level
	)			const [protected, virtual]

Registers a process control at the channel's reset list.

Parameters:

	pctrl	The process control object that shall be deactivated in case of a reset.
	active_level	The reset trigger level (high or low).

See also:

rc_process_control

Implements rc_reset_channel_if.

Definition at line 665 of file rc_process_support.cpp.

void unregister_process_control

(

rc_process_control &

pctrl

)

const [protected, virtual]

Unregisters a process control from the channel's reset list.

Parameters:

pctrl

The process control object that shall be unregistered

The opposite of register_process_control().

rc_process_control

Implements rc_reset_channel_if.

Definition at line 675 of file rc_process_support.cpp.

virtual bool get_current_level

(

)

const [inline, protected, virtual]

Returns the reset channel's current level.

Returns:

the current level of the channel.

Implements rc_reset_channel_if.

Definition at line 296 of file rc_process_support.h.

virtual const sc_signal<bool>* get_underlying_reset_signal

(

)

const [inline, protected, virtual]

Returns the underlying SystemC signal (if such exists).

Returns:

a SystemC signal this channel is based on.

Note:

SystemC's reset mechanism is not standardised. Hence for some SystemC implementations (e.g. OSCI SystemC) it may be useful to have access to a native channel.

sc_core::sc_signal_inout_if::reset_is()

Implements rc_reset_channel_if.
