FPGA and nios II data sharing

Hi, 

 

For an application I need to put uClinux onto the nios II core. I want to do some of the resource heavy stuff like operate NCOs and read/write DACs/ADCs in hardware and then have a linux program do certain things with the data.  

 

I appologize if im asking a question that has been answered 100 times but I have looked and couldn't find much. 

 

Is it possible to transfer data between fpga code and a linux program? Obviously HAL or watever its called is out of the question. Is the easiest way to put it in a shared memory location in RAM or something?
