Question

How is each data type represented internally in Intel Pentium® D processors?

Answer 1

Intel Pentium D processors are Refers to Dual-core 64-bit micro processors are designed by the Intel company.

Data types supported by Intel pentium D processors:-

Data types                                                                                    Representation

1.General                                 ------       representation of byte in 8-bits,and word in 16-bit,double word in 32-bit,and

                                                              quad word in 64-bits.

2.Integer                                   -----       A signed integer converted into binary format and it's 2's complement

                                                             representation is used in intel processors.

3.Floating point                       ------       float pointing numbers is represented in single precision of 32-bit,and          

                                                             double precision with 64-bit, extended double precision with 80-bits.

4.BCD Data type                      -------      It is in packed BCD and unpacked BCD represetation.

       packed BCD                     -------      1 byte per 2 digits representation

                                                            2 BCD digits packed within 8-bits with the value ranging from 0-99.

      unpacked BCD                  --------     1 byte for 1 digit representation

                                                             representation of 4-bits decimal number range from 0-9.

5.Ordinal                                ---------     An unsigned integer value represented in any length within 64-bit.

6.Character string                  --------      represented by interpreted through the string of bytes.
