TIVA C Series Bluetooth and Camera I/F

Tushar Patel

Here is the Simplified Diagram.

I want to use Camera (OV2640) with parallel interface to capture JPEG image from camera(built in JPEG DSP processor to output JPEG image) size is around 640X480 pixels. the frequency of data is around 4-6MHz and the size of FIFO is 3Mb.

Which one would be best in terms of speed TIVA C series or MSP430?

the work of controller is to get image basically JPEG from camera and send it over bluetooth to iOS/Andriod device.

Is there any EPI support in TIVA for FIFO buffer RAM ?

or any other suggestion?

    Tushar,

    I think the TM4C129X family of devices would be well suited for your applications.  Is includes a 120MHz Cortex M4F (~150DMIPS) and an EPI interface supporting speeds upto 60MHz.

    I recommend you cross-post this request on Low Power RF & Wireless Connectivity Forums for the Bluetooth side of the design.  I know they have ported the StoneStreet One Bluetopia stack to run on TM4C123x micro controllers and should be a fairly straightforward to get running on a TM4C129x.

    Regards,

    Chris

    Chris,

    thanks for suggestion

    I have already posted this on Bluetooth application side.

    I have datasheet for the TM4c129x where datasheet  have mentioned about connection of fifo buffer to EPI port.

    but I am not getting any detailed description or application notes on connecting FIFO buffer ram to EPI port.

    and can I know why would MSP430 couldn't work in this situation, is it because of its low I/O speed than TIVA?

    Regards,
