Member Function Documentation

CNode * NoCMapping::addUsageNode ( CNode * systemUsageNode )

addUsageNode () Create an XML node which describes the usage of the links in the interconnect. This node is added to the systemUsageNode supplied to the function. The systemUsageNode is also returned by the function. The function also updates the used incoming and outgoing bandwidth of the NIs inside the tiles based on the communication schedule.

CNode * NoCMapping::createMappingNode ( )

createMappingNode () Create an XML node which describes the mapping of messages send over the interconnect to the resources in the interconnect.
