HI all I'm doing the barcode reader using Rasperry Pi and Simulink. I'm stucking in separate the image into RGB like Deinterleave that can be used for Texas Instrument C6000. Is there any similar thing like that for Raspberry Pi? Thank you very much for any help

Raspberry Pi V4L2 Video Capture block can output images in planar RGB or YCbCr 4:2:2 formats. For barcode scanning, I would think that you want to use a YCbCr output and perform barcode detection on the Y component. Since data is in planar format, you should not need to de-interleave the image at all.
Are you getting the image data from somewhere else where it is interleaved? What is the format of the input?

The support package for Raspberry Pi converts a Simulink model targeted for Raspberry Pi to a Linux application and saves it on the SD card of the Raspberry Pi board. You can find the d in application in the following folder on your Raspberry Pi:
/home/<user name>/<model name>_rtt/MW/<model name>
For example, if you have a model called "barcode.slx" and your user name is 'pi', Simulink generates the following executable:
/home/pi/barcode_rtt/MW/barcode
You can run this application anytime. Your Raspberry Pi does not have to be connected to your host computer.
You can also auto-start your application on boot by placing the following line of code at the end of /etc/rc.local file:
/home/pi/barcode_rtt/MW/barcode &> /dev/null &
