Detailed Description

Arbitrary precision unsigned arithmetic.

This file includes the definitions of sc_unsigned_bitref, sc_unsigned_subref, and sc_unsigned classes. The first two classes are proxy classes to reference one bit and a range of bits of a sc_unsigned 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.

It is also important to note that an sc_unsigned number with n bits is equivalent to an sc_signed non-negative number with n + 1 bits.

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.
