Member Function Documentation

String m2m.backend.buildingblocks.blocks.Sub2Comb32.author ( ) [virtual]

Returns the author of the VHDL file.

Returns:: the author name

Implements m2m.backend.buildingblocks.BuildingBlock.

Definition at line 50 of file Sub2Comb32.java.

int m2m.backend.buildingblocks.blocks.Sub2Comb32.cycleTime ( )

Indicates the cycle time of the building block. For a standard pipeline implementation, it should be 1, as a new calculation can be launched at every clock cycle. For a sequential implementation it should return the number of clock cycles required for a processing, if this is known, 0 else. For a combinatorial implementation, it is not relevant.

Returns:: the cycle time

Reimplemented from m2m.backend.buildingblocks.BuildingBlock.

Definition at line 25 of file Sub2Comb32.java.

ArrayList<String> m2m.backend.buildingblocks.blocks.Sub2Comb32.dependentFiles ( ) [virtual]

Returns the names of the VHDL files the block needs.

Returns:: Names of dependent VHDL files.

Implements m2m.backend.buildingblocks.BuildingBlock.

Definition at line 65 of file Sub2Comb32.java.

String m2m.backend.buildingblocks.blocks.Sub2Comb32.description ( ) [virtual]

Returns a description of the building block. It can then be exploited to display a list of available components.

Returns:: a description of the block

Implements m2m.backend.buildingblocks.BuildingBlock.

Definition at line 60 of file Sub2Comb32.java.

String m2m.backend.buildingblocks.blocks.Sub2Comb32.entityName ( ) [virtual]

Returns the name of the VHDL entity describing the block.

Returns:: the name of the VHDL entity

Implements m2m.backend.buildingblocks.BuildingBlock.

Definition at line 45 of file Sub2Comb32.java.

String m2m.backend.buildingblocks.blocks.Sub2Comb32.functionName ( ) [virtual]

Returns the name of the function implemented by the block. All blocks performing the same function should return the same name. It has to be fixed for the operators, and can be user defined for functions.

The basic functions HAVE to respect there names:

multiplication: mult
division: div
addition: add
subtraction: sub
square root: sqrt
exponential: exp

Other functions can be added, such as sin, cos, ... The name returned by functionName() should then be the same as the one used in the mathematical source code.

Returns:: the name of the function calculated by the block

Implements m2m.backend.buildingblocks.BuildingBlock.

Definition at line 40 of file Sub2Comb32.java.

ImplType m2m.backend.buildingblocks.blocks.Sub2Comb32.implType ( ) [virtual]

Returns the implementation type, that can be SEQUENTIAL, PIPELINE, or COMBINATORIAL. It may help the optimizer to choose the most appropriate component for a given application.

Returns:: The implementation type

Implements m2m.backend.buildingblocks.BuildingBlock.

Definition at line 15 of file Sub2Comb32.java.

int m2m.backend.buildingblocks.blocks.Sub2Comb32.latencyTime ( )

Indicates the latency time of the building block. For a pipeline implementation, it returns the number of pipe stages, while for a sequential implementation it returns the number of clock cycles required for a processing, if this time is known, 0 else. For a combinatorial implementation it returns 1.
