Memory or other speed and feature enhancements are seamlessly absorbed by the
U‐Boot firmware, giving a consistent look and feel to the operating system and
the user application as the GEIP hardware models advance. This allows the
constant use of latest technology in required areas without system impact. Where
particular operating systems define the use of alternate boot methods (e.g.
VxWorks BootROMs), the U‐Boot firmware technology is absorbed into such boot
methodology.
BCS supplements the BIT initialization test coverage with further health screening
that can co‐exist with a standard COTS Operating System.
In contrast to a traditional BIT‐style test, the intensity and coverage of which
makes it destructive to operating systems, the configurable BCS package allows
functions such as periodic check‐summing, memory scrubbing, and others to be
tailored for operation alongside the application in on‐line conditions. Results are
stored in Flash in the same format as BIT results. Code is available for reading out
BIT/BCS results under LynxOS and VxWorks.
