Member Function Documentation

create()

StreamGen * gem5::StreamGen::create ( const BaseTrafficGenParams & p )

static

Factory method for constructing a Stream generator.

The Stream generator type is selected by the StreamGenType enum parameter.

@params p pointer to BaseTrafficGenParams struct where the stream generator type is stored.

Returns

a pointer to the newly alocated StremGen

pickStreamID()

virtual uint32_t gem5::StreamGen::pickStreamID ( )

pure virtual

Implemented in gem5::FixedStreamGen, and gem5::RandomStreamGen.

pickSubstreamID()

virtual uint32_t gem5::StreamGen::pickSubstreamID ( )

pure virtual

Implemented in gem5::FixedStreamGen, and gem5::RandomStreamGen.

ssidValid()

bool gem5::StreamGen::ssidValid ( ) const

inline

Returns true if the substreamID generation is valid and hence should be taken into account.

It is valid if the set of substreamIDs passed as a parameter to the TrafficGenerator is a non empty list.

Returns

true if ssid is valid, false otherwise

Member Data Documentation

streamIds

std::vector<uint32_t> gem5::StreamGen::streamIds

protected

Store preset Stream and Substream IDs to use for requests This is the set of available streamIDs the generator can pick.

The actual ID being picked for a specific memory request is selected by the pickStreamID and pickSubstreamID methods.
