Member Function Documentation
◆ recvRangeChange()
|
inlineprotectedvirtual |
Called to receive an address range change from the peer response port.
The default implementation ignores the change and does nothing. Override this function in a derived class if the owner needs to be aware of the address ranges, e.g. in an interconnect component like a bus.
Reimplemented from RequestPort.
Definition at line 72 of file RubyPort.hh.
◆ recvTimingResp()
|
protectedvirtual |
Receive a timing response from the peer.
Implements TimingRequestProtocol.
Definition at line 171 of file RubyPort.cc.
