News & Press Green Hills Software Expands Total Solution For Versatile Intel Network Processor Fastest Growing Real Time Operating System, INTEGRITY, Supports Intel IXP425 Network Processor San Francisco, April 22, 2003 -- Green Hills Software, Inc., the technology leader in real-time operating systems and embedded development software, today announced support for the Intel IXP425 network processor with its INTEGRITY real-time operating system (RTOS). For the first time, application developers now have a high performance RTOS integrated with the industry leading MULTI integrated development environment (IDE) and optimizing C/C++ compilers to develop and deploy their network-enabled products using WAN and LAN technologies for small-to-medium enterprises.   "We have seen phenomenal response to our IXP4XX product line in high-end gateway, voice over IP, wireless access points, industrial control, medical and networked imaging applications," said Jim Finnegan, general manager, Intel Network Processor Division. "With Green Hills Software products and technology now tailored for the Intel IXP425 network processor, developers have an optimized, royalty-free development solution that both reduces time-to-market and cost-to-deploy."   INTEGRITY is a modern, royalty-free RTOS that is optimized for Intel XScale technology, and well suited for applications based on the Intel IXP425 network processor that require high performance, high reliability, and a cost-effective business model. Royalty-free licensing eliminates per-unit cost True real-time performance with fast interrupt response and rapid context switching Guaranteed memory and CPU availability Full access to kernel and board support source code Integrated with Green Hills Software's MULTI IDE, optimizing compilers and JTAG hardware debug probes in an easy-to-use, single source solution Integrated support for the three Network Processing Engines on the Intel IXP425 network processor Utilizing the Intel IXP425 network processor's memory protection unit (MMU) for full memory protection for user data, the kernel, device drivers and user tasks Field debugging and field upgradeable Complete integrated networking solutions for IPv4/v6, IPSec, Secure Web, Firewall and RADIUS and Crypto support   INTEGRITY enhances reliability and determinism by never disabling interrupts during any system call while providing applications guaranteed access to the CPU and memory for critical tasks. INTEGRITY prevents errant or malicious code from corrupting user and kernel objects. Other RTOS solutions do not offer this protection or security, leaving systems vulnerable to failure from errant application code, viruses, and hackers.   The Intel IXP425 network processor is a highly integrated, versatile single-chip processor that can be used in a variety of products that need network connectivity and high performance to run their unique WAN and LAN applications. It is powered by the Intel XScale RISC core running at up to 533 MHz and offers integrated hardware acceleration of popular cryptography algorithms, three IPSec-enabled Network Processor Engines, two high-speed serial ports for VoIP SLIC/CODEC or T1/E1 and associated DSP software, two integrated 10/100 Base-T Ethernet MACs, UTOPIA 2 interface with multiple ADSL/G.SHDSL or VDSL support, USB version 1.1 device controller, 33/66 MHz PCI v2.2 host and low system power consumption (1.0 -1.5 Watt typical).   INTEGRITY is part of a complete, highly integrated, single-source development solution for the entire application development project, from board bring-up, to product development and deployment, to in-field debugging and upgrades. The MULTI IDE includes a source-level debugger, program builder, profiler, run-time error checker, version control, memory leak detector and editor. Green Hills Software's C/C++/EC++ compilers are optimized for the Intel XScale core, ARMV5T Thumb instruction set and ARM V5E DSP extensions, thus continuing the tradition of producing the fastest and smallest code in the industry.   MULTI also features the 100% binary compatible INTEGRITY simulator (ISIM), which enables programmers to develop and test their target processor code on a PC or workstation without the Intel IXP425 network processor hardware; and a real-time EventAnalyzer and ResourceAnalyzer, which give users a view of system and user events in a graphical display. The Green Hills Probe and Slingshot provide on-chip debugging and user run-control at downloads speeds of 450KB/sec.   INTEGRITY for the Intel IXP425 network processor is available in May 2003. MULTI and the Green Hills Probe are available now.   More on Green Hills Software   Founded in 1982, Green Hills Software Inc. is the technology leader for real-time operating systems and software development tools for 32- and 64-bit embedded systems.
