All Implemented Interfaces:

BooleanFlags, Clockable, Pipelineable, byucc.jhdl.base.Propagateable, TreeListable

public class FPPack

extends Logic

implements Pipelineable

General Description

A helper module which packs floating point values for output.

The FPPack module allows selection of zero, infinity, NaN, and normal numbers as outputs.

Implementation

All Technologies

This module is technology independent.

Future Work

A future version of this module may support (optionally) registered outputs for pipelining.
