Performance evaluation of a microcontroller

[EmbeddedManiac]

Hello everyone,

I am new in this field. I want to use bluetooth low energy enabled cc2540 microcontroller for image transfer. Before that I want to know whether this particular microcontroller is able to do image processing (even if it is slow) or not.
Is there any technique to or any piece of code that I can use to evaluate the performance?
I would also like to know what experts do when they decide for a microcontroller for a particular application.

Thank you.

I don't think BLE is a good choice to transfer images. Over GATT you will be able to transfer max 20bytes per packet. Compared to Bluetooth classic the data rate will be very less. But still it is up to you, if you don't mind the speed then yes you can transmit images.

Cc2540/1 is having advanced 8051 CPU core. But it is not enough for image processing. By the word image processing I am assuming you are asking some thing similar to opencv libs running on an embedded Linux or windows. For such things first you need a lot of RAM and then processing power. Also I think the a user application will have the least priority if a Bluetooth stack is running on it. If you really want to do some very basic image processing you can go for Stm32f4 series controllers with external Ram interfaced to it.

it depends what you mean by'image processing' and 'slow'
for image processing applications I would look at DSP systems, e.g.
