How do I choose ARM based processors?

Applies to: Processor Cores


You are working on a new design and want to choose an ARM based processor. The questions at this point could be:


ARM is a fabless company. This means that ARM does not manufacture silicon. ARM designs processor cores and licenses them to its silicon partners. The silicon partners, in turn, design microprocessors / microcontrollers around these cores and manufacture the actual silicon or chips available for commercial purchase in the market.

In case you are keen to know more about the ARM Cores than the silicon variants of the processors available in the market, you may refer to the Processor Overview section on our website. This section provides a lot of information on our processor families, the architecture, features, reference methodologies, etc. which would a good starting point. If you wish to see more detailed documents on our cores, you may also refer to our InfoCenter - the documentation section on our website.

For more information on our silicon partners, please refer to the Connected Community section on ARM's website.

Choosing an ARM based processors may involve lot of technical and non-technical considerations. A partial list could look something like this:

Most of these aspects are silicon driven and would be better addressed by our silicon partners who manufacture these cores, or would need your internal assessment to decide upon. To start with, you may refer the following URLs for more information:

For more information or support on any of the above commercially available processors, we would suggest that you contact the manufacturer directly.
