LogiCORE Generic Framing Procedure (GFP) v1.2 - UNMAP Core (64-bit) loses sync on some frames if barker-scrambling is off

描述

If barker-scrambling is Off, then a frame that ends in at least 32 0's might cause the synchronization logic to process it as an idle in the stream, and cause the expected alignment of the next frame in the stream to be incorrect. Theoretically, this situation can also happen if barker scrambling is On, and a frame either ends in "B6AB31E0", or contains this in the ending bytes.

解决方案

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