SAN JOSE, Calif., April 3 /PRNewswire-FirstCall/ -- EMBEDDED SYSTEMS
CONFERENCE SILICON VALLEY, BOOTH #1746 -- QNX Software Systems, the
industry leader in multi-core processing for embedded systems, announced
today a new OS partitioning solution for multi-core systems that offers the
ultimate in system security and guaranteed realtime performance. The new
QNX(R) Secure Partitioning for Multi-Core Processors offers the world's
first and only secure memory and CPU partitioning capability for multi-core
systems.
Partitioning schemes of today are limited to uniprocessor designs.
Because current implementations do not offer a holistic view of multiple
cores, developers who wish to protect their systems from untrusted
applications or rogue attacks must attempt to partition each core
separately, usually by proliferating multiple copies of the OS on each
core.
QNX Secure Partitioning for Multi-Core Processors takes the current
restrictive concepts of software partitioning and dramatically changes the
rules. Embedded developers using multi-core hardware can apply secure
partitions in their designs to guarantee realtime response times and
contain threats, while simultaneously maximizing resource usage and
performance.
QNX Secure Partitioning for Multi-Core Processors offers designers the
flexibility to either lock down a set of applications in fixed partitions
or optimize CPU utilization through adaptive partitions. In fact, a
multi-core design can employ the two techniques simultaneously, depending
on the prioritization of each function. QNX partitioning technology
guarantees CPU time for applications when the system is heavily loaded. It
can also dynamically reassign unused resources from partitions not under
full load to those that need additional processing time, providing a higher
level of performance by increasing CPU utilization. This approach is far
more efficient than traditional partitioning solutions, which waste memory
and CPU cycles through their rigid and fixed resource allocations.
When combined with QNX's multiprocessing solutions, secure partitions
can be implemented in a variety of configurations for a multi-core design.
For instance, by using QNX's unique Bound Multiprocessing (BMP) option,
designers can "bind" selected applications to a specified set of CPU cores,
creating a true hardware and software partitioning capability.
QNX Secure Partitioning for Multi-Core Processors not only addresses
the need for secure operation and realtime performance, but can also speed
system design by allowing engineers to preallocate guaranteed system
resources for subsystems added later in the design cycle.
To maximize ease-of-use and application portability, QNX Secure
Partitioning for Multi-Core Processors and the QNX Neutrino(R) microkernel
RTOS use industry-standard POSIX APIs, allowing embedded developers to
employ the exact same task-prioritization schemes that they use today. QNX
Neutrino offers other inherent security benefits, such as isolating
drivers, protocol stacks, and applications in separate, memory-protected
virtual address spaces. As a result, malicious or poorly written software
cannot corrupt, disrupt, or spy on other processes.
Availability
QNX Secure Partitioning for Multi-Core Processors is commercially
available now, with memory-partitioning capabilities to be available for
beta trials in August 2007.
