Write to SRAM in vhdl; Then read into NIOS?

I would like to write data to a specific SRAM address using verilog (no nios) and then access that same memory address using the NIOS processor. The main purpose for this is to execute a video pro...

The easiest way would be I think to design your own SOPC component, with an Avalon Master interface. Thus the component will be able to write to the memory, and the SOPC builder will automatically add some arbitrators to share the memory accesses between your component and the NIOS CPU.

Using a DMA component is another solution, depending on how you want to access the memory.
