RTOS Based On Cortex M3 for Image Grabbing and Processing In High Speed
Mon Apr 22 2013, 05:40 pm
Hi ajay & guys,
I need to do image processing with based ARM cortex m3 but i am not much familiar with RTOS so could you please give me some idea about RTOS with cortex m3.
i am planning to use Camera link communication.
also suggest any starter kit which have low cost. Note : my processing speed should support max 10 kHz (grabbing speed of image from camera and display in GUI. its like a frame grabber card i am expecting.
Thanks in advance

I am not sure about any CM3 controller with camera link interface. But you might M3 controllers with camera interfaces from ST micro. I found a link where STMicro kits are given, see if you can find anything useful there.

Thanks ajay thats fine!
camera link is not must i can use some external chips for converting to interface camera
The main thing is to start with RTOS on ARM.. so can you give some ideas on RTOS which is Easy to Start .

there is nothing like install in embedded RTOS you just have to port the code and build it like you do with any other code. it will generate a hex file load the hex and you have a RTOS running on your device.

hi ajay,
Thanks for the info.
I am thinking of displaying the image in the real time(UI ) . so if i use windows RTOS it will be much easier to do such things .
Also i can call the API for displaying in Pc monitor which makes my job Easy
So if i use embedded RTOS is it easy to display the image in Qvga or TFT ??

@pravin, Windows RTOS? hmm.. I never heard of it. RTOS can do everything you want him to do, provided you have good programming skills. coz usually display needs regular updates and screen refreshes, which can be done using a regular task. But if you screen is complicated to handle then it becomes difficult for a small controller and rtos. I believe Qvga should not be difficult but depends on your UI. and you need a good library to handle displays.
As Mohan mentioned "mini 2440 Board" which is capable of running linux on it and has a display. Linux has framebuffer that manage your display and anything that is being displayed on it
