Precision Must be Set When Using Lanczos Coefficients in Scaler - Precision Must be Set When Using Lanczos Coefficients in Scaler Description When configuring the Scaler MegaCore function, you must choose the correct coefficient precision when using Lanczos coefficients. This issue affects configurations of the Scaler MegaCore function using the polyphase algorithm with Lanczos coefficients. The MegaCore function fails to generate. Resolution If you select polyphase mode with Lanczos coefficients, you must set the coefficient precision to be signed with one integer bit. Fraction bits can be set within the full range available in the MegaWizard interface. The coefficient precision restriction will be enforced in future versions of the Video and Image Processing Suite.
