Introduction
============
document isn't a replacement for any manufacturers specifications for FPGA
usage.
-
Terminology
===========
a soft logic bridge (Bridge0-2) in the FPGA. The contents of each PRR can be
reprogrammed independently while the rest of the system continues to function.
-
Sequence
========
When the overlay is removed, the child nodes will be removed and the FPGA Region
will disable the bridges.
-
FPGA Region
===========
hardware bridges remain enabled. The PR regions' bridges will be FPGA bridges
within the static image of the FPGA.
-
Supported Use Models
====================
