Amd Processors

Aswin Kumar Bala KrishnanMIS 502 AMD64 Processor Architecture Introduction: The AMD 64 is a 64 hour processor currently available in the market. It is an filename extension of x86 types of processors, it similarly includes the compatibility of the 32 subbroadcast processors. The first version of AMD 64 was released in April 2003. It was named Opteron. The AMD 64 provides 16 64 bit normal designing registers 16 SSE (Streaming SIMD instructions) registers. SMID stands for Single Instruction threefold Data. The AMD64 ABI (Application binary Interface) was developed from 32 bit ABI. Programs that atomic number 18 compiled by a 32 bit ABI green goddess be tryout in 64 bit ABI but the performance of the program leave alone be better when compiled with a 64 ABI. Data types: The master(prenominal) characteristics of the 64 bit processors ar the general use registers; thither are 64 bit of internal registers where as its wholly 32 bits in case of a 32 bit processor. H ere the operations can be performed straight off on 64 bits. However the stack operations are performed in 8 bits. The dissimilar entropy types supported by the AMD64 are A. underlying types 1. Integral 2. shoot forer 3. Floating Point 4. Decimal floating Point 5. Packed The sizes of assorted info types are mentioned in the tabular column 1.1.

on that tear down are three main programming models for a 64 bit processor * LP64 * ILP64 * LLP64 The naming is used in such a way to represent the 64bit variable. In LP64 Long and computer address are 64 bits, in ILP64 Integer, Long and Re ference are 64 bits and in LLP only Double (! Long Long) is 64 bits. The different data sizes were mentioned in the tabular format 1.0. B. point handle Bit fields are always non contradict, even though they sustain data types which can set about negative values they have the same size and range of the unsigned type. * Allocation is make from right to left. * They must be stored in a unit of measurement according to the declared type. * They can share a remembering unit with other data members.
