Member Function Documentation
◆ clock_cb()
|

Definition at line 42 of file reordering_target.cpp.
◆ snoop_resp()
|
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()
|
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 >.

◆ fw_i

Definition at line 29 of file reordering_target.h.
◆ max_latency
| sc_core::sc_attribute<unsigned> axi::pe::tx_reorderer::max_latency {"max_latency", 100} |
the maximum time a transaction is allwed to stay in the target
Definition at line 35 of file reordering_target.h.
◆ min_latency
| sc_core::sc_attribute<unsigned> axi::pe::tx_reorderer::min_latency {"min_latency", 10} |
the minimum time a transaction will stay in the target
Definition at line 33 of file reordering_target.h.
◆ 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.
◆ prioritize_by_qos
| sc_core::sc_attribute<bool> axi::pe::tx_reorderer::prioritize_by_qos {"prioritize_by_qos", false} |
use the QoS field for selection.
Definition at line 43 of file reordering_target.h.
◆ reorder_buffer
|
protected |
Definition at line 67 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
