Hi,
I am a novice to the field of embedded development. I have taken up a project on image processing for protyping.If things g fine, the sytem may have few hundred units in production.The syste specifications are as follows:
i) A CCD camera to capture the image. ii) An embedded system to process the image. Includes about 6 filterin operations, one compression. (The processing needs to be done in 1-2 sec gray image of 256*200 pixels).Finally an encrypting the data befor storing. iii) Store the image in a CF memory available. iv) A few pheripherals like a key pad and lcd display. v) Interface to USB and Ehternet(TCP/IP).
As I am not very comfortable with designing hardware, I was looking for SOC kind of chip for this project.
After some amount of reading I decided to base my system on ARM core Mainly due to the availabilty of the tools. I have come up with a few designs.
i) To use an Atmel(AT91SAM9 series) based processors. A development kit is available. But does not have an interface to connec the composite video o/p from the camera.
ii) To go for an Atmel (AVR32 series) + a TI based dsp processor. I could not find any kits. No idea how to proceed.
iii) A bit expensive, but base the design on OMAP 5912, using th OMAP5912OSK.
I am planning to base the sytem on eCOS in case of atmel based design. Fo OMAP, I am planning to use linux with DSPGateway.
Can you please help me with i)Letting me know if my design choices are right. ii)If any other alternate designs are possible. iii)I am still at loss on how to digitise my composite video o/p. (Ther are a few ic's I came across from philips and ti), Can I get any read made module, which I can plug in with my system on I2c or SPI?
Thanks and Regards, Ram
