Writing to SRAM from VHDL and using NIOS

It would help me very much if someone explained me the steps that have to be taken to make a solution. I am busy for days now but the more I know, the more I get confused.

The goal here is that I want to give in a 32bit SRAM adress with the 16bit value, just like it can be done from C. But now from a VHDL perspective. I know, I am a complete FPGA noob:D, but I need to get the job done. I would appreciate it very much if someone could give me a bit of guidance.
