1. A SEMINAR ON
64 BIT COMPUTING

2. 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

3. 64-bit Computing

4. Is 64-bit Computing necessary?

5. 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.

6. 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.

7. 32-bit vs. 64-bit Processors

8. 64-bit Registers

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

10. AMD Athlon 64 FX Processor
