Execute the step.
compute non-shared resources
check easy binding and compute the list of vertices for which a sharing is possible
in case no vertices was left we have done
check for PHIs attached to the ouput. They may require one or more muxes.
rank property map definition
parent property map definition
merge easy bound vertices
add the vertices to the cdfc graph
add the control dependencies edges and the chained edges to the cdfc graph
only the chained operations are relevant
pipelined operations break false loops
add compatibility edge with computed weight on both the directions
compute levels
topologically sort vertex of CD_EDGE based graph
remove all cycles from the cdfc graph
remove the loop
remove both the compatibility edges
search another loop
partition vertices for clique covering or bind the easy functional units
check easy binding
solve the binding problem for all the partitions
build the clique covering solver
add vertex to the clique covering solver
add the edges
only one edge is needed to build the undirected compatibility graph
Specify the minimum number of resources in case we have to use all the memory ports. That is relevant for memories attached to the bus Private memories should use the minimum number of ports to minimize the total area.
performing clique covering

retrieve the solution
compute maximum starting time
storing new binding results
