13 years agoSending interrupt to a custom logic.
Hi,
I hope I'm posting in the right section. I need a DMA Controller for my project. I am not using a NIOS system with it and I want to trigger a custom logic circuit when the data transfer is over. From the manual of DMA controller in SOPC builder, I got the idea that I can read the Status register of the Controller repeatedly to check whether the transfer is finished or not. Which i might do, but I was wondering if it is possible to use the interrupt that the controller generates at the end of a transaction to trigger the circuit. Is it possible to receive the interrupt with a my circuit? If possible, how? I don't see any way to export or use any bridge with the 'irq' terminal present in the DMA CONTROLLER in SOPC builder. Thank you.
