Nios II+uClinux frambuffer in single SDRAM

[Altera_Forum]

Hi All, 

 I am intending to run uclinux on NIOS 2/f on cyclone 3 fpga. I have one SDRAM 32MB connected to the cyclone 3.  The system is connected to CCD sensor, I would like video to be streamed to another computer via ethernet.  I have seen couple of IP camera design solutions that use 2 SDRAMs (1 for ucLinux, 1 for frame buffer). I woundn't want this approach as I have space and IO constraints to go with 2 SDRAMs on the board.  Would it be possible to run both uclinux (nios 2) and frame buffer on the same SDRAM?  Highly Appreciate any pointers.  Thank you
