A SEMINAR ON 64 BIT COMPUTING

64-bit Computing The best and simple definition is enhancing the processing word in the architecture to 64 bits. Data processing speed does not change yet the data processed in a clock cycle increases two times. The addressable memory increases from 4 GB to 264 = 18 billion GB

64-bit Computing

Is 64-bit Computing necessary?

Benefits of 64-bit Computing Allowing applications to store vast amount of data in main memory Manipulating data and executing instructions in chunks that are twice as large as in 32-bit computing. Allowing complex calculations with a high-level precision.

32-bit Computing In a 32-bit microprocessor; There are 32-bit general purpose registers in the processor. There are 232 = 4GB memory to be addressed.

32-bit vs. 64-bit Processors

64-bit Registers

AMD Athlon 64 FX Processors The AMD Athlon™ 64 FX processor is the world’s best PC processor.” -- AMD Inc.

AMD Athlon 64 FX Processor Key features: AMD64 Technology Hypertransport Technology DDR Memory Controller On-Die Cache 3DNow!Technology

Performance Tests The performance of the processor is tested in three different computation areas. Computer Gaming Digital Media Office Productivity

Conclusion 64-bit computing is a necessary technology in the computer science areas which require larger memory and increased performance such as scientific computing, CAD/CAM, ERP/CRM solutions etc... With new technologies improved, today AMD Athlon 64 FX – 55 processors have the best potential to fulfill 64-bit desktop computing needs.
