Signed Vertical Coefficients and Unsigned Horizontal Coefficients (or Vice Versa) with Sum of Coefficients More Than 1 Cause Scaler II to Generate Incorrect Output

Environment

    Quartus® II Subscription Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT

Critical Issue

Description

The Scaler II MegaCore function may generate incorrect output when you use signed vertical coefficients with unsigned horizontal coefficients (or vice versa) and the sum of the coefficients for one or more phases is more than 1.

This issue affects all configurations that use the polyphase and bicubic algorithms with the Scaler II MegaCore function.

The affected configuration may generate incorrect output.

Resolution

None available.

This issue will be fixed in a future version of the Video and Image Processing Suite.
