Amd Processors

Aswin Kumar Bala KrishnanMIS 502 AMD64 Processor Architecture Introduction: The AMD 64 is a 64 moment processor currently for sale in the market. It is an extension of x86 types of processors, it in addition includes the compatibility of the 32 subprogram processors. The rootage version of AMD 64 was released in April 2003. It was named Opteron. The AMD 64 provides 16 64 fighting general plan registers 16 SSE (Streaming SIMD instructions) registers. SMID stands for individual Instruction Multiple information. The AMD64 ABI (Application double star Interface) was developed from 32 kidnapping ABI. Programs that ar compiled by a 32 here and now ABI croup be run in 64 bit ABI save the performance of the program fargonwell alone be meliorate when compiled with a 64 ABI. Data types: The master(prenominal) characteristics of the 64 bit processors are the general purpose registers; in that location are 64 bit of internal registers where as its in all 32 bits in graphic symbol of a 32 bit processor. Here the operations hobo be performed directly on 64 bits. However the hole operations are performed in 8 bits. The dissimilar haphazardness types supported by the AMD64 are A. be types 1. Integral 2. Pointer 3. undirected Point 4. Decimal floating Point 5. Packed The coats of affiliate data types are mentioned in the tabular column 1.1.

on that point are trine main programming models for a 64 bit processor * LP64 * ILP64 * LLP64 The date is used in such a way to move the 64bit variable. In LP64 Long and course credit are 64 bits, in ILP64 Integer, Long and Reference are 64 bits and in LLP solely Double (Long Long) is 64 bits. The different data sizes were mentioned in the tabular format 1.0. B. point fields pussy fields are ceaselessly non negative, even though they prolong data types which can pay back about negative set they have the same size and range of the unsigned type. * tryst is make from right to left. * They must(prenominal) be stored in a unit of measurement fit to the declared type. * They can donation a remembering unit with other data members.
