The camera controller controller design reads images from the camera and sends them to the Gumstix.
Images
The OV7670 camera can be configures for different image sizes and frame rates.
Image size
In this design, the images are stored in the FPGA memory. The Spartan-6 LX100 FPGA has:
- 122 KB distributed RAM
- 603 KB Block RAM built out of 4.5 KB blocks
Using less than half the available Block RAM would result in a 256 KB (218) memory. Using 1 byte per pixel, this allows for a 512 x 512 image.
