Member Function Documentation

void axi::pe::rate_limiting_buffer::snoop_resp	(	tlm::tlm_generic_payload &	payload,
		bool	sync = `false`
	)

inlineoverridevirtual

send a response to a backward transaction if not immediately answered

Parameters

payload	object with (optional) extensions
sync	if true send with next rising clock edge of the pe otherwise send it immediately

Definition at line 74 of file ordered_target.h.

void axi::pe::rate_limiting_buffer::transport	(	tlm::tlm_generic_payload &	payload,
		bool	lt_transport = `false`
	)

overridevirtual

execute the transport of the payload. Independent of the underlying layer this function is blocking

Parameters

payload	object with (optional) extensions
lt_transport	use b_transport instead of nb_transport*
