Member Function Documentation

◆ add_protocol_cb()

void axi::pe::axi_initiator_b::add_protocol_cb	(	axi::fsm::protocol_time_point_e	e,
		std::function< void(payload_type &, bool)>	cb
	)

inline

register a callback for a certain time point

This function allows to register a callback for certain time points of a transaction (see #axi::fsm::protocol_time_point_e). The callback will be invoked after the FSM-actions are executed.

Parameters

e	the timepoint
cb	the callback taking a reference to the transaction and a bool indicating a snoop if true

Definition at line 122 of file axi_initiator.h.

◆ snoop_resp()

void axi::pe::axi_initiator_b::snoop_resp	(	payload_type &	trans,
		bool	sync = `false`
	)

overridevirtual

triggers a non-blocking snoop response if the snoop callback does not do so.

Parameters

trans
sync	when true send response with next rising clock edge otherwise send immediately

Implements tlm::scc::pe::intor_fw< type::BL >.

Definition at line 359 of file axi_initiator.cpp.

◆ transport()

void axi::pe::axi_initiator_b::transport	(	payload_type &	trans,
		bool	blocking
	)

overridevirtual

The forward transport function. It behaves blocking and is re-entrant.

This function initiates the forward transport either using b_transport() if blocking=true or the nb_transport_* interface.

Parameters

trans	the transaction to send
blocking	execute in using the blocking interface

Timing

Implements tlm::scc::pe::intor_fw< type::BL >.
