Detailed Description

This class represents the base class for a building block performing calculation on floating point numbers. It allows to set the number of bits for the exponent and the significand, in order to generate correct VHDL. By default, the VHDL components are considered to be generic.

Member Function Documentation

final NumType m2m.backend.buildingblocks.BuildingBlockFloat.numType

(

)

[virtual]

Returns the numbers type (NumType.FLOAT).

Returns:

NumType.FLOAT

Implements m2m.backend.buildingblocks.BuildingBlock.

Definition at line 24 of file BuildingBlockFloat.java.

boolean m2m.backend.buildingblocks.BuildingBlockFloat.setSize	(	int	significandSize,
		int	exponentSize
	)

Sets the size of the exponent and the significand, in bits.

Parameters:

significandSize	Total size of the significant
exponentSize	Total size of the significant

Returns:

false if the number of decimal bits is greater than the total number of bits, or if one of these numbers is negative, true else.

Definition at line 48 of file BuildingBlockFloat.java.

boolean m2m.backend.buildingblocks.BuildingBlockFloat.useGenericSize

(

)

Indicates if the operands have a generic size or not. For fixed point data, the default is yes, as generic building blocks should be quite easy to describe.

Returns:

true

Reimplemented from m2m.backend.buildingblocks.BuildingBlock.
