IP: Frame Buffer II (4K Ready)

Why does my Frame Buffer II drop every other output sample?

Description

Due to a problem with the Frame Buffer II IP Core prior to Quartus® Prime Software version 17.0, you will see this behavior if you select the 128 bit Avalon®-MM master(s) local ports width.

Workaround/Fix

To work around this problem, select the 256 bit local ports width.  Qsys® will automatically insert a width adapter if you need to connect to other 128 bit slaves.

This problem has been fixed starting in the Quartus Prime software version 17.0.
