WILSONVILLE, Ore., Oct. 26, 2015 /PRNewswire/ -- Mentor
Graphics Corporation (NASDAQ: MENT) today announced an update to
the Mentor® Embedded Nucleus® real time operating system (RTOS)
targeting low power, next-generation applications for connected
embedded and internet of things (IoT) devices. The Nucleus RTOS
supports the development of safe and secure applications utilizing
the ARM® TrustZone® in
Cortex®-A processors. The ARM TrustZone
technology provides a system approach to create processor
partitioning that isolates both hardware resources and software to
help create a "secure" world that is protected from software
attacks.
Non-secure applications are executed in the non-isolated domain
– the "normal" world – without the ability to impact the
applications executing in the secure world. Devices with safety and
security operating requirements can isolate and execute secure
applications on the Nucleus RTOS in a trusted environment with
priority execution over the non-secure applications in the normal
world. Devices requiring a safe domain with dedicated
peripherals for trusted applications to support secure software
updates, digital rights management, and trusted payments will
benefit from the hardware partitioning technology provided by the
ARM TrustZone. This release of the Nucleus RTOS also
includes support for low power, resource constrained IoT devices
with 6LoWPAN and 802.15.4 wireless connectivity.
The explosive growth of smart IoT connected devices with the
proliferation of cloud-based services places new requirements on
developers to protect assets from software attacks. The ARM
TrustZone enables embedded system developers to allocate
system peripherals such as secure memory, crypto blocks, wireless
devices, LCD screens, and more to a secure operating domain that is
isolated from the remaining system. This hardware separation
allows for the development of separate, secure applications on
Nucleus RTOS in a trusted environment.
"For IoT and other connected applications, the expanded security
and low-power connectivity features in Mentor's Nucleus RTOS
provide many of the capabilities needed for the creation of complex
heterogeneous IoT systems," stated Markus
Levy, founder and president of EEMBC and The Multicore
Association. "These features complement leading-edge hardware
capabilities to meet the needs of today's advanced IoT embedded
systems."
The applications in the secure world have access to all the
system resources while a secure monitor acts to ensure the priority
execution over the non-secure normal world applications. The
secure monitor provides complete isolation to allow for the
execution of bare metal, Linux® or Nucleus RTOS-based applications
in the normal world without impacting the safe Nucleus RTOS-based
applications in the secure world. The Nucleus RTOS with ARM
TrustZone makes it possible to selectively secure
peripherals and applications for system isolation to meet safety
and security requirements.
"Nucleus RTOS support for ARM TrustZone provides system
developers with the ability to meet the highest levels of safety
and security for critical applications for heterogeneous OS-based
systems," states Scot Morrison,
general manager of runtime solutions, Mentor Graphic Embedded
Systems Division, "ARM TrustZone isolates the general purpose
operating system, bare metal or Nucleus RTOS in the normal world
from the secure application running in Nucleus RTOS in the secure
world."
IoT wearables, portable medical devices, home automation
systems, and other smart connected devices are routinely designed
with limited system resources to reduce power consumption and
extend battery life. Designed for low data rate IP-driven
communication, IPv6 over Lower Power Wireless Personal Area Network
(6LoWPAN) is an adaptation layer that can be used to connect
resource-limited IoT devices to the internet using IP network links
like Ethernet, WiFi, or low power wireless connections. The Nucleus
RTOS enables the development of IoT devices with 6LoWPAN to allow
the low power exchange of data using TCP, UDP, CoAP transport
protocols with compatible application layer security protocols such
as DTLS. The use of IPv6 addressing allows every IoT device to have
a routable IP address to facilitate internet and cloud access using
the standard IP network infrastructure. For low power devices,
embedded IoT developers can use 6LoWPAN over 802.15.4 wireless
communication. With the Nucleus RTOS, IoT end nodes can be
connected, monitored and updated using cloud-based
services.
