MICROKERNEL
Green Hills Software has two royalty-free
RTOS products. The POSIX conformant
INTEGRITY
®
RTOS
is memory-protected
and securely partitioned for use in embedded
systems that require the utmost in reliability
and security. The
velOSity™
microkernel
,
the foundation of
INTEGRITY
, is small and
fast, making it a perfect fit for cost-sensitive,
high-volume, and resource-constrained
embedded applications.
INTEGRITY
and
velOSity
employ common
application programming interfaces, device
drivers, BSPs, middleware and network stack
support, along with a common MULTI
®
tools
integration and debug features. Software
developed for the
velOSity
microkernel
is 100% upwards compatible with the
INTEGRITY RTOS
. In applications that may
require virtual memory support,
velOSity
can
be upgraded to
INTEGRITY
with minimal
to no code changes. Should the system
design call for partitioned application and
device drivers, the existing design can be
easily reconfigured to enable applications
and device drivers to exist in their own
protected virtual address partition.
