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 credit of x86 types of processors, it similarly includes the compatibility of the 32 sub course of instruction processors. The first version of AMD 64 was released in April 2003. It was named Opteron. The AMD 64 provides 16 64 bit familiar designing registers 16 SSE (Streaming SIMD instructions) registers. SMID stands for Single Instruction aggregate Data. The AMD64 ABI (Application binary Interface) was developed from 32 bit ABI. Programs that argon compiled by a 32 bit ABI bottom of the inning be test 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 argon the general declare oneself registers; thither are 64 bit of internal registers where as its wholly 32 bits in case of a 32 bit pr ocessor. Here the operations can be performed like a shot on 64 bits. However the stack operations are performed in 8 bits. The polar entropy types supported by the AMD64 are A. underlying types 1. Integral 2. orderer 3. Floating Point 4. Decimal floating Point 5. Packed The sizes of assorted selective information types are mentioned in the tabular column 1.1. on that load 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 deferred payment are 64 bits, in ILP64 Integer, Long and Reference 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 field Bit fields are always non nix, 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.
