Connecting Custom Logic to M4K block?

[Altera_Forum]

Hi,  

 I have built a system which loads images from SDCARD to the onchip memory in Cyclone II in DE2-70 board using NIOS II IDE and C code ..  Now I need my custom logic modules to read the image from the memory to do some processing, how do I connect my custom logic to the SOPC instantiated M4K block and read the loaded values from it?  Should my custom verilog module be added as a component in SOPC to resolve this  Thanks

Yes, you need to wrap your custom logic into a custom SOPC component so that you can connect it to the SOPC system. 

 You'll either want to  a) design your custom component with an Avalon-MM interfance and DMA capable b) design your custom component with an Avalon-ST interface and use the "sgdma" component to perform DMA  Or maybe a third option: When reading the image from the SDCARD, store it directly into your custom component, instead of having a separate onchip memory component.
