◆ BitUnion64()

gem5::X86ISA::I82094AA::BitUnion64 ( RedirTableEntry )

◆ getPort()

Port & gem5::X86ISA::I82094AA::getPort	(	const std::string &	if_name,
		PortID	idx = InvalidPortID )

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

Reimplemented from gem5::SimObject.
