FPLIC ParaCore Parameters

ParaCore Architect parameters for the Floating Point Library IP Core.

Dillon Engineering’s Floating Point Library IP Core contains all the elements required to implement a high-performance floating point system.

MODULE PARAMETER TYPE DESCRIPTION Addition Subtraction Division Multiplication Reciprocal Square Root type nType The nType definition is used to specify the width of the exponent and mantissa (see also the notes below) special Boolean Set to True in order to implement IEEE 754 special-case tracking stages Integer Specifies the number of pipeline stages to be used Convert iType nType Specifies the input data type (see also the notes below) oType nType Specifies the type of the output data (see also the notes below) stages Integer Specifies the number of pipeline stages to be used

 

The following table defines the nType parameter, which is used to define the number types to be implemented by ParaCore Architect:

PARAMETER TYPE DESCRIPTION type Select Select number type (options are int or float). width Integer For type == int, this parameter sets the integer width. For type == float, this parameter is automatically set to e_width + m_width + 1 (see below). e_width Integer When type == float, this parameter defines the width of the exponent (it should be set to 8 for single precision and 11 for double precision). m_width Integer When type == float, this parameter defines the width of the mantissa (it should be set to 23 for single precision and 52 for double precision).
