LogiCORE Generic Framing Procedure (GFP) v1.2 - UNMAP Core (64-bit) loses synchronization when a certain pattern of frames is received


The GFP Core can lose synchronization on the frame following the very short frame when the 64-bit GFP Core is in "parallel hunt" or "idle hunt" mode. This occurs when a frame is received in the input stream with a total of n+1, n+2, or n+3 bytes ("n" is a multiple of 8 bytes), and is followed by a very short (4 byte) frame.


This issue has been fixed in the GFP v1.3 release available with the 8.1i IP Update #1.
