ContributorVVP Scaler Coeff
Hello, I am evaluating the VVP Scaler function but not able to find any document mentioned about how to generate the coefficient and update it.. Do you have any data can share? Thank you.
Hi JLee25 ,
For a reference code/design like the old VIP suite that shows on-the-fly coefficient generation: No — I did not find that in the documents/URL we read. The old example page only says the design scales video; it does not show coefficient-generation logic.
For whether VVP Scaler supports runtime coefficient updates: Yes — the user guide says that if runtime coefficient updates are enabled, you can write coefficient values to the coefficient memory via the Avalon-MM interface.
