Green Hills Software Announces INTEGRITY(TM) Real-Time Operating System For ARM Processors
Protects Kernel and Applications from Errant Code, Viruses and Hackers
SAN FRANCISCO--(BUSINESS WIRE)--March 13, 2002--Green Hills
Software today announced the availability of its INTEGRITY(TM) 4.0
real-time operating system for the ARM® family of processors,
including the ARM720T(TM) core, the ARM920T(TM) core, the ARM922T(TM)
cores and the ARM® architecture-compliant Intel® XScale(TM)
microarchitecture.
INTEGRITY provides full memory protection and guaranteed resource
availability, while still delivering a worst-case interrupt latency of
less than 200 nsec, and a worst-case context switching time of less
than a microsecond. This unique combination makes INTEGRITY a secure,
ultra-reliable, high-performance target environment for deploying
embedded ARM applications in a variety of networked, consumer
electronics products.
Most ARM processors include a memory management unit (MMU) that
can protect user tasks from each other and prevent unintended access
to the kernel. However, very few RTOS products for ARM support the
MMU. As a result, these products offer no protection against errant
code. This lack of protection can allow application bugs free reign to
affect not only the application, but the entire system, ultimately
causing a kernel crash. By contrast, INTEGRITY's modern architecture
provides full support for the ARM MMU, offering tremendous protection
for today's security-focused, network environment.
"INTEGRITY's memory protected architecture, guaranteed resource
availability and fast, deterministic, hard real-time response make it
the most secure and reliable RTOS solution on the market today, and
the only royalty-free, memory-protected commercial RTOS," said John
Carbone, vice president of marketing at Green Hills Software. "Now,
designers of ARM Powered® applications, who already enjoy the
productivity and code optimization benefits of our MULTI® Integrated
Development Environment (IDE) can deploy ARM applications on the most
reliable RTOS, with full I/O, networking and debug support, without
paying royalties."
"This RTOS provides an attractive protected memory, multi-tasking
solution for the high-performance, low-cost, low-power market areas
where ARM technology is deployed," added Rod Crawford, director of
third-party software products for ARM.
INTEGRITY is a fast, deterministic, real-time operating system
designed for applications that require high reliability, availability,
security and testability. Utilizing the hardware memory protection
facilities of ARM MMUs, INTEGRITY builds a firewall between the kernel
and user tasks that prevents errant or malicious tasks from corrupting
user data, the kernel, interprocess communications, device drivers and
other user tasks. INTEGRITY also enhances reliability and determinism
by running with interrupts continuously enabled and guaranteeing
access to the CPU and memory for critical tasks. Other RTOS solutions
do not offer this protection or security, leaving systems vulnerable
to failure from a single errant application, virus or hacker attack.
INTEGRITY provides comprehensive I/O and file system support,
including a USB stack, NFS client, drivers for I2C, CompactPCI/VMEbus
backplanes, clocks, timers and standard PC peripherals, and a
full-featured, UNIX-compatible, hierarchical file system. Networking
support includes a TCP/IP stack, Gigabit Ethernet driver, and the full
line of Trillium communications protocols, including SS7, ATM, ISDN,
Frame Relay, MPLS, VoIP and 3G wireless. INTEGRITY also supports the
full line of InterNiche and Allegro embedded Internet products, which
make it easy to add Web connectivity and management to embedded
systems.
INTEGRITY is tightly integrated with Green Hills' MULTI IDE.
Together with Green Hills' family of optimizing C, C++ and EC++,
compilers, MULTI automates all aspects of embedded software
development for ARM processors, including editing, source-level
debugging, program building, run-time error checking, version control
and code/performance optimization. MULTI also features ISIM, an
INTEGRITY simulator that enables programmers to develop and test their
code on a PC or workstation without the need for target hardware.
The MULTI debugger enables programmers to simultaneously debug
multiple INTEGRITY tasks across multiple address spaces task, whether
those processes reside on a single processor, or are distributed
across multiple processors. MULTI automatically activates a new
debugger window when a process is created, and provides a process
roster window for tracking process and choosing which process to
debug. Through MULTI, programmers can set process-specific and
address-space-wide breakpoints, and monitor/record I/O and
interprocess communications. They can also perform execution profiling
at the process, address space or system level to precisely pinpoint
performance bottlenecks.
INTEGRITY's graphical Resource Analyzer greatly enhances
visibility into applications and the kernel as they execute on the
target system, displaying CPU execution at the task and address space
level, stack usage for tasks, and memory use for address spaces.
INTEGRITY's real-time EventAnalyzer(TM) further enhances real-time
visibility by enabling programmers to log and monitor system and
application events in real time without disrupting program execution.
Operating like a high-level logic analyzer, the EventAnalyzer displays
all INTEGRITY context switches, API calls, and interrupts in a
time-relative manner using intuitive ICONs. The EventAnalyzer is also
tightly integrated with Rational's RoseRT, enabling programmers to
view RoseRT state transitions and INTEGRITY events.
INTEGRITY is available immediately for ARM core-based solutions,
including the Intel XScale microarchitecture, and works out of the box
with a variety of popular ARM core-based evaluation boards, including
Cirrus Logic's EDB72xx board based on the ARM720T core, Sharp's
Reference Board based on the ARM922T core, and Intel's IQ80310 XScale
board. Green Hills also offers a porting kit and turnkey porting
services for designers who want to port INTEGRITY to other platforms.
Development licenses for the INTEGRITY RTOS, including a board
support package, start at $15,000 per product. Run-time licenses for
INTEGRITY on the target system are free.
