Polling or interrupt on a custom module signal???

Hi, I've design a Nios system in which I insert my custom module interfacing it using the slave MM wrapper. This custom block receives a start command and sends 32 bit data (values from 32 to 126)...

Alternatively, if you have a very simple 'round robin' scheduler (not really a scheduler at all) that just call each 'task' running on your card in turn, it may well be simplest to just check the 'need data' / 'data available' bit every time the scheduler loop calls the task.

That might mean you need to instrument (and optimise code for) the 'worst case' code path.
