The first two classes are + proxy classes to reference one bit and a range of bits of a + sc_signed number, respectively. + + An sc_signed number has the sign-magnitude representation + internally. However, its interface guarantees a 2's-complement + representation. The sign-magnitude representation is chosen + because of its efficiency: The sc_signed and sc_unsigned types are + optimized for arithmetic rather than bitwise operations. For + arithmetic operations, the sign-magnitude representation performs + better. + + The implementations of sc_signed and sc_unsigned classes are + almost identical: Most of the member and friend functions are + defined in sc_nbcommon.cpp and sc_nbfriends.cpp so that they can + be shared by both of these classes. These functions are chosed by + defining a few macros before including them such as IF_SC_SIGNED + and CLASS_TYPE. Our implementation choices are mostly dictated by + performance considerations in that we tried to provide the most + efficient sc_signed and sc_unsigned types without compromising + their interface. + + For the behavior of operators, we have two semantics: the old and + new. The most important difference between these two semantics is + that the old semantics is closer to C/C++ semantics in that the + result type of a binary operator on unsigned and signed arguments + is unsigned; the new semantics, on the other hand, requires the + result type be signed. The new semantics is required by the VSIA + C/C++ data types standard. We have implemented the new semantics. + + Original Author: Ali Dasdan, Synopsys, Inc. + + *****************************************************************************/ + +/***************************************************************************** + + MODIFICATION LOG - modifiers, enter your name, affiliation, date and + changes you are making here. + + Name, Affiliation, Date: + Description of Modification: + + *****************************************************************************/ + +// $Log: sc_signed.h,v $ +// Revision 1.3 2011/08/24 22:05:46 acg +// Torsten Maehne: initialization changes to remove warnings. +// +// Revision 1.2 2011/02/18 20:19:15 acg +// Andy Goodrich: updating Copyright notice. +// +// Revision 1.1.1.1 2006/12/15 20:20:05 acg +// SystemC 2.3 +// +// Revision 1.5 2006/05/08 17:50:01 acg +// Andy Goodrich: Added David Long's declarations for friend operators, +// functions, and methods, to keep the Microsoft compiler happy. +// +// Revision 1.4 2006/03/13 20:25:27 acg +// Andy Goodrich: Addition of function declarations, e.g., xor_signed_friend() +// to keep gcc 4.x happy. +// +// Revision 1.3 2006/01/13 18:49:32 acg +// Added $Log command so that CVS check in comments are reproduced in the +// source. +// + +#ifndef __SYSTEMC_EXT_DT_INT_SC_SIGNED_HH__ +#define __SYSTEMC_EXT_DT_INT_SC_SIGNED_HH__ + +#include <iostream> + +#include "../misc/sc_value_base.hh" +#include "../sc_temporary.hh" +#include "sc_length_param.hh" +#include "sc_nbdefs.hh" +#include "sc_nbexterns.hh" +#include "sc_nbutils.hh" +#include "sc_unsigned.hh" + +namespace sc_dt +{ + +// classes defined in this module +class sc_signed_bitref_r;
