Detailed Description

Explorer plugin that selects implementations for units in a given adf. Creates a new config with a idf.

Supported parameters:

ic_dec, name of the ic decoder plugin, default is DefaultICDecoder
ic_hdb, name of the HDB that is used in IC estimation, default is asic_130nm_1.5V.hdb
adf, if idf is wanted to generated to some arhitecture, no default value. If adf parameter is given the idf is built.

Member Function Documentation

◆ explore()

virtual std::vector<RowID> ImplementationSelector::explore	(	const RowID &	startPointConfigurationID,
		const unsigned int &	maxIter
	)

inlineprivatevirtual

Explores the design space from the starting point machine and returns best exploring results as configuration IDs.

Exploring creates new machine configurations (architecture, implementation) that are ordered so that the best results are first in the result vector.

Parameters

startPoint	Starting point machine configuration for the plugin.
maxIter	Maximum number of design space points the plugin is allowed to explore. Default value for maxIter is zero when the iteration number is not taken into account. In that case the exploration runs indefinetly or stops at a point defined by the algorithm.

Returns: Ordered vector of IDs of the best machine configurations where the target programs can be successfully run. The IDs of the best machine configurations are first in the result vector. Returns an empty vector if does not find any possible machine configurations.
