◆ drainResume()

overridevirtual |
◆ getPort()
|
overridevirtual |
Get a port with a given name and index.
This is used at binding time and returns a reference to a protocol-agnostic port.
gem5 has a request and response port interface. All memory objects are connected together via ports. These ports provide a rigid interface between these memory objects. These ports implement three different memory system modes: timing, atomic, and functional. The most important mode is the timing mode and here timing mode is used for conducting cycle-level timing experiments. The other modes are only used in special circumstances and should not be used to conduct cycle-level timing experiments. The other modes are only used in special circumstances. These ports allow SimObjects to communicate with each other.
- Parameters
-
if_name Port name idx Index in the case of a VectorPort
- Returns
- A reference to the given port
