-- Package name: STD_LOGIC_UNSIGNED --
-- --
-- --
-- Date: 09/11/92 KN --
-- 10/08/92 AMT --
-- --
-- Purpose: --
-- A set of unsigned arithemtic, conversion, --
-- and comparision functions for STD_LOGIC_VECTOR. --
-- --
-- Note: comparision of same length discrete arrays is defined --
-- by the LRM. This package will "overload" those --
-- definitions --
