Nios II+uClinux frambuffer in single SDRAM

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

Maybe, it's possible. But please be careful about the bus bandwidth. Also you may need a special frame buffer driver.
