Amd Processors

Aswin Kumar Bala KrishnanMIS 502 AMD64 Processor Architecture Introduction: The AMD 64 is a 64 hour processor currently addressable in the market. It is an extension of x86 types of processors, it withal includes the compatibility of the 32 subprogram processors. The scratch line version of AMD 64 was released in April 2003. It was named Opteron. The AMD 64 provides 16 64 oddball general calculative registers 16 SSE (Streaming SIMD instructions) registers. SMID stands for single(a) Instruction Multiple information. The AMD64 ABI (Application binary Interface) was developed from 32 tour ABI. Programs that are compiled by a 32 raciness ABI deal be run in 64 bit ABI alone the performance of the program have alone be check when compiled with a 64 ABI. Data types: The master(prenominal) characteristics of the 64 bit processors are the general purpose registers; thither are 64 bit of internal registers where as its wholly 32 bits in nerve of a 32 bit processor. Here the operations evict be performed directly on 64 bits. However the plug operations are performed in 8 bits. The varied reciprocal ohm types supported by the AMD64 are A. key types 1. Integral 2. Pointer 3. vagrant Point 4. Decimal floating Point 5. Packed The sizes of various(a) data types are mentioned in the tabular column 1.1.

on that point are third main programming models for a 64 bit processor * LP64 * ILP64 * LLP64 The assigning is used in such a way to champion the 64bit variable. In LP64 Long and credit entry are 64 bits, in ILP64 Integer, Long and Reference are 64 bits and in LLP only(prenominal) Double (Long Long) is 64 bits. The different data sizes were mentioned in the tabular format 1.0. B. point fields bit fields are of all time non negative, even though they arrive data types which can passel about negative set they have the same size and range of the unsigned type. * apportionment is make from right to left. * They moldiness be stored in a unit of measurement of measurement gibe to the declared type. * They can cope a remembering unit with other data members.
