virtual void ComputeUnit::SQCPort::recvRangeChange ( )

inlineprotectedvirtual

Called to receive an address range change from the peer slave 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 MasterPort.

void ComputeUnit::SQCPort::recvReqRetry ( )

protectedvirtual

Called by the slave port if sendTimingReq was called on this master port (causing recvTimingReq to be called on the slave port) and was unsuccesful.

Implements MasterPort.
