DSP for digital still camera

Jared Johnson1
Prodigy 40 points

I am attempting to make a digital still camera with a CMOS sensor with SD card and LCD support.  Here are the peripheral descriptions:

-1.3 Mp CMOS sensor, 10 bit parallel pixel data and I2C communication

-QVGA graphic LCD, 18 bit parallel data and possibly 4 analog pins for resistive touch screen

-SD card, SPI communication

-Possible UART connection via USB

-Multiple push buttons to interrupt-capable GPIOs

-Output pins to LEDs

-Random other input/output and PWM pins

At 1.3 Mp, 24 fps, and an estimated 25 cycles per processed pixel, I presume that I need a DSP over 780 MHz (some parameters can be altered if necessary).  What TI DSP IC would be best for this?

    Hi Jared,

    Please refer to www.ti.com/ipcamera for TI's camera reference designs. The processors used in those camera designs also support LCD interface.

    Hi Jacob,

    Thanks for the advice, but I have already looked at the DaVinci line. It is an extremely powerful IC so much so that it far exceeds what I am looking to do with my digital still camera. It is also quite expensive. I don't claim to know much about the DaVinci, but it seems to be for video applications which lie outside of my project parameters. I posted in the C6000 DSP line because that seemed like the closest DSP IC that suited my needs. I was just looking for any advice on finding a cheap DSP to use for my project and not a finished product.

    Thank you,

    Jared
