ARM is the company of choice when it comes to processors for tablets or mobile devices. You can find the designs on all kinds of electronic appliances from washing machines to TVs even passing cars.
We are talking about more than 90% market share by taking into account all these devices.
To understand how it has come to achieve this we need to understand how it works. Its work is based on three types of licenses which acquire other companies, which are ultimately creating the devices:
- The Simplest. In this case you purchase a processor design and are free to take it to a manufacture to produce.
- The Guided. They help you throughout the process, including the manufacturing process to be used and the company that will take care of this is decided. Normally this is selected when you want to get certain benefits.
- The More Complex. In this case you only pay for implementing the instruction set design and all you have to do it yourself. This way you get more freedom. It is what makes your micros Qualcomm Snapdragon or Apple in their latest creations.
The entire system is designed for companies from Sony to LG or Samsung, they are as simple as possible, but the truth is that the buyer can get lost and not really knowing you are buying.
Always bear in mind that an ARM processor can be modified to certain benefits and then compare two terminals only considering the micro model can be misleading.
What has Prepared ARM Tablets for 2015?
Since ARM does not lead to designs that make devices that use may be several years since the makeup you can purchase. No further requires editors to choose one or the other micro or characteristics associated with so do not be surprised if some of these models do not see them until 2016.
Differentiating between the models 32 and 64 bits have the following models:
32 bits ARMv7
The ARMv7 instruction set is being used in almost all tablets less recent Air and iPad Mini iPad Retina.
Here for several years have been using models Cortex A7 and A9. The latter, for example, to see what they are lived, has had four different versions.
- Cortex A12. Replaces the Cortex A7. We may classify as mid-range call. There are already some implementations
- Cortex A15. It is used even in some of Google ChromeBook notebooks. Be identified with the high range. Is supposed to be the successor to the A9. It is 40% faster than the previous using the same energy. You can big. Little settings with the A7.
- Cortex A17. It is the evolution of the A12 wills therefore midrange. Also you’ll find in big. Little A7 configurations. It is 60% faster than the A9.
64 bits ARMv8
It seems that the future of tablets passing the 64-bit instruction set ARMv8. In this area we find the following models:
- Cortex A53. Low range is considered. Designed to accompany the A57 in big. Little configurations. It would be what is now an A7 but with support for 64-bit instructions.
- Cortex A57. Super high range. Maybe the micro to mark the entry of ARM in the PC world.
