Member Function Documentation

SDFtime BindingAwareSDFG::computeLatencyAMBAbus ( CSize tokenSize ) [private]

computeLatencyAMBAbus () The function takes as an argument the size of a token (in bits) and returns the time needed to transfer this token over the AMBA bus.

void BindingAwareSDFG::constructBindingAwareSDFG	(	TimedSDFgraph *	constrainedSDFG,
		PlatformGraph *	platformGraph,
		SDFflowType	flowType
	)			`[private]`

constructBindingAwareSDFG () Create a binding-aware SDFG for the constrained SDFG taking into account the properties of the platform graph and the mapping as specified in the same graph. Note that this function is just a shell to select the correct flow model. The actual binding-aware SDFG construction is done in a different function.
