How do I determine the latency of my filter?
Currently, without doing a simulation, there is no way to determine the latency of the core. You can run the simulation and watch the RDY signal.
For cores compiled using this release, the latency of a particular filter implementation can be determined by performing a simple simulation of the core netlist. For example, by passing an impulse (a single non-zero sample with either zero samples or, when using ND, no samples before or after) into the core and checking the cycle count to the first output which follows that sample.
This will be addressed in the next release.
