Using OCRAM as a buffer instead of SDRAM for a camera application

Greetings all,

From my understanding of the camera based applications in AN12103 and AN12110 (webcam and camera to LCD/JPEG respectively), the SDRAM is just used as a buffer until the data is consumed. The data is consumed continuously to display on the LCD, compress as JPEG (needs 8 rows to start compressing if I understand correctly) or stream over USB. So a whole image isn't stored on the SDRAM, which means even the internal RAM can also be used with the OCRAM peripheral.

Is my understanding correct? Can broad level pointers be provided to change these applications to use the internal SRAM? Thanks.
