Detailed Description

Since all the HLS packages use this module to retrieve technology information (see src_HLS_allocation_page for details), it is also used to introduce a simple functional unit allocator (see Binding constraints for details).

It returns a list of functional units compatible with the graph under analysis. Each functional unit is represented by an id of unsigned int type. Given this id, all the HLS packages can retrieve:

• performances (i.e., execution time, initiation time, power consumption, area of the functional unit)
• constraints (number of available functional units) On the other hand, the hls_flow class can control the allocation of the functional units during the instantiation of the allocation object.
