I need a little digital io for my project since cortex-m is not economical for me I need to know can i use Cortex-a to do some embedded jobs?
Please can you describe in more detail what you are trying to accomplish?
What sort of processing power do you need? if it
What additional functionality do you need?
You mention Digital I/O (how many, what functionality etc).
The more information you can provide the better quality the answers you will receive.
Hope this helps
I want to use it for DSP applications and signal generating for motor control.
Have you considered a 300MHz Cortex M7 from Atmel?
ATSAME70 and ATSAMV7x devices also have CAN interfaces etc.
Combines MCU and DSP functionality offering similar performance to entry level 32bit DSP's.
Also one of the applications it is targeting is Motor control.
Cortex-As have more powerful DSP instructions becuase of SIMD and NEONStill Performance/price of Cortex-As are higher than Cortex-Ms.
I think you can have a look at NXP i.MX6 series products
