Very often, the term is used in the description of the bit of computing devices and systems, thus meaning the number of bits which are simultaneously stored, processed, or transmitted to another device.However in the case of a CPU is the most complex element of a computer iron, which are not divided into individual elements, this concept can be very vague.And there may be a legitimate question: how to define the word length of the processor?Let us investigate.How do I know
bit processor: the criteria for determining
We can use three criteria to determine this parameter function, realizable, standard.By functional commonly understood as processing, storage and exchange.Under realizable - the physical and architectural level.And under the standard - addresses and data.It turns out that we deal with 12 kinds of obscure concepts, and the question, how do you know the bit processor, remains unresolved.For example, we can call 16-bit word length, if at all levels of the value is exactly 16 bits.However, 32-bit, we need to consider to what criteria should the figure be that way.If we talk about the data, then it is possible to assume that they are stored in this format, but the addresses of such can be said.If you deal with every level of realization, we find ourselves in a very difficult situation, when the corresponding bit processors is difficult to find a set of parameters.The processor does not have to process the data and addresses in 32-bit format, as for this there are special operands are capable of operating with dual 16-bit data.
How do you know the bit processor, and the challenges we face?
Gradually, we can conclude that the physical plane in the processor does not have to do a 32-bit, you must convince the programmer only in architectural terms, the processor performs operations and commands in the 32-yuitnom format.And how do you know the bit?Programmers do not have to worry how physically implemented bit, if he works 32-bit.If you organize all the information, we can conclude that there is a real opportunity to increase the resolution of a 16-bit processor and 32-bit, but here we are faced with the expediency of such a decision.If the processor works with the existing configuration is normal, there is no guarantee that an increase in bit by software it will run faster.It is likely that there will be difficulties associated with reading data and address in the new format, which can take extra time.It makes no sense to do 32 bits on 16-bit processor capable of quickly enough to process information in 32-bit format, as this is also a negative impact on performance.From all this we can draw the following conclusion: the bit is increased so that it is possible to achieve qualitative and quantitative increase in productivity of the whole architecture.
How do you know the bit processor programmatically
Since modern software can be designed for a specific bit CPU, there is a need to define it.You can use this task to applications CPU-Z or AIDA 64. To determine the bit processor with the help of the program CPU-Z, you must start it after installation, after which the CPU tab will display information about the processor.For 32-bit processors use the notation «x86»,null, and «x64» - for 64-bit.To determine the type of processor using the AIDA 64, you need to install and run.To the left of the main window, select "Computer" - "System board" - "CPU".After that you will see all the information about the processor, including its bit.
