Example Of A 64 bit Processor.
Okay..so here is where we start off our discussion about processors. The first subject that I will touch is 64 bit processing/computing.
I'm sure you must have heard stories /reports about 64 bit processing. But what exactly is 64 bit processing? 64 bit CPU architectures are those that are based on registers, address buses or data buses of that size. A 64 bit platform CPU generally supports 64 bit of integer data. This system holds more memory and performs larger number of calculations comparative to lower bit platforms.
Understanding Bits
A bit is a single 1 or 0 integer processed/stored by a transistor in the CPU. All processors are differentiated by the bit processing ability (data calculations). The bit rating of a processor (Ex. 32bit, 64 bit) concludes the largest number the processor can handle (Kyrnin, 2007). A number greater than that will require more than 1 clock cycle. A 32 bit processor handles a number up to 4.3 billion but a 64 bit processor can handle a number up to 18.4 quintillion!!! (Kyrnin, 2007)This concludes that a 64 bit processor reduces clock cycles and is more efficient in large number mathematics.
64 bit architecture makes working with huge data sets in application such as digital video, scientific computing, and large databases easier and faster. Not only speed but applications like multi-tasking and clustering are better suited for 64 bit architecture.
Memory
32 bit chips can address up to 4 GB of memory with the maximum allocation to any program is 2 GB. A 64 bit on the other hand can address up to 16 exabytes of memory (over 16 billion GB of memory!!). This isnt a big deal for remote computers but its a huge boost for super computers and servers. The biggest benefit is obviously the data transfer rate as pulling bits out of the memory is 60,000 times faster than from the hard disk.
If computers are to increase in processing speed, it is neccessary to take the 64 bit platform seriously. System that require more memory and large calculations will directly reap rewards from the 64 bit chip. Therefore it is clear that 64 bit computing holds the key to the next generation of processors.
