Member Function Documentation

◆ snoop_resp()

void axi::pe::tx_reorderer::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

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

Definition at line 59 of file reordering_target.h.

◆ transport()

void axi::pe::tx_reorderer::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*

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

Member Data Documentation

◆ prioritize_by_latency

sc_core::sc_attribute<bool> axi::pe::tx_reorderer::prioritize_by_latency {"prioritize_by_latency", false}

use the waiting time as priority value - the longer a transaction waits the higher the probability becomes to be selected

Definition at line 41 of file reordering_target.h.

◆ window_size

sc_core::sc_attribute<unsigned> axi::pe::tx_reorderer::window_size {"window_size", 2}

minimum number of transaction to start with reordering. If the total number is below the threshold transaction will stay for max_latency
