Introduction
SystemC has large number of data types to support modelling of Hardware as well as modelling of fractional fixed-point. Since SytemC is based on C++, it supports all the data types of C++. 

Choice of datatypes to use depends on synthesiability, level of abstraction and simulation speed.

• C++ Data Types
• Bit Type
• Logic Type
• Arbitrary Width Bit Type
• Arbitrary Width Logic Type
• Signed Integer Type
• Unsigned Integer Type
• Arbitrary Precision Signed Integer Type
• Arbitrary Precision Unsigned Integer Type
• Resolved Types
• User-defined Data Types

Numeric Representation
To support hardware data representations, SystemC provides a unified string representation using C-style strings. It is possible to convert both to and from this format. SystemC uses the following syntax for strings:

sc_string name ("0 base [sign] number e[+/-] exp]");

Here

• name : Name of the variable
• base : b for binary, o for octal, d for decimal and x for hexa decimal
• sign : us for unsigned, sm for signed magnitute, csd for canonical signed digit
• number : Number is an integer in the indicated base
• exp : The optional exponent exp is always specified using decimal
  C++ Data Types
  SystemC supports all the C++ data types listed below.

• int
• long int
• unsigned int
• unsigned long int
• unsigned short int
• short
• float
• char
• bool

All the above data types are covered in C++ chapter. Refer to C++ chapter if you want to know more on C++ data types.
