News & Press Analog Devices And Green Hills Software Collaborate On Embedded Development Tools For Blackfin Processor NORWOOD, Mass. April 23, 2003 -- Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal processing applications, and Green Hills Software Inc., the global technology leader for real-time operating systems and embedded software development tools, announced today a collaboration to jointly design embedded development tools for ADI's Blackfin® Processor. The companies have developed a multi-year product roadmap for hardware and software development tool solutions that will provide full support for ADI's Blackfin Processor with Green Hills Software's existing industry-leading tools, such as the award-winning MULTI® Integrated Development Environment (IDE); C, C++ and EC++ compilers; Green Hills Probe™ and Slingshot™ probe. These tools offer embedded system developers a best-in-class solution that will address all of their development needs as well as broad operating system support, thereby enabling them to get their products to market in a faster and less expensive manner.   ADI's Blackfin Processors combine best-in-class digital signal processing performance with microcontroller functionality and embedded operating system support. They are designed to meet the computational demands and power constraints of today's embedded audio, video and communications applications, such as portable media players, digital still and video cameras, streaming A/V applications, car telematics, smart handheld devices, video telephones and voice-over-IP systems. Blackfin Processors support signal processing algorithms as well as embedded operating systems and control code in a single, unified architecture. These new tools will provide full development support for application developers as well as for several memory-protected and non-memory protected operating systems.   Green Hills Software's technology combines industry-leading software development tools for algorithm and application development with support for a wide range of embedded operating systems, including its industry-leading INTEGRITY® real-time operating system (RTOS). From system simulation to OEM system deployment, Green Hills Software technology helps companies save time throughout a project development lifecycle with powerful features, efficient design and by eliminating the need for engineers to learn different tools and user interfaces.   "Analog Devices' Blackfin Processor has been designed to support large applications including mainstream embedded operating systems, DSP middleware, control code as well as providing high performance for embedded audio, video and communications," said Brian McAloon, group vice president, DSP, media and systems division, Analog Devices, Inc. "As a result, we continue to build the support infrastructure that can support the full range of embedded applications that are being targeted for the Blackfin Processor family. Because of their leadership in the embedded systems market, Green Hills was a natural choice for us to collaborate with in this joint development."   "We see Analog Devices' Blackfin Processor as a breakthrough product in several ways," said Dan O'Dowd, president and CEO of Green Hills Software, Inc. "Its architecture lets users carry out both the signal processing functions and control functions that are needed to produce complete products in a broad range of markets. The breakthrough price-performance of the recently announced Blackfin family of processors is well-suited for the small, fast operating systems such as Express Logic's ThreadX® that customers need to minimize product costs. However, as these applications increase in size and complexity, reliability becomes an increasingly important consideration. In those markets memory management becomes an architectural necessity in order to support a high reliability operating system such as INTEGRITY. Blackfin's memory management makes it possible to provide those reliability levels."   The first jointly developed tools product release is planned later this year. Future releases are planned to support a broad range of operating systems such as INTEGRITY, ThreadX and more. With this level of support, embedded system developers who have their own operating system or who are considering Linux or a mix of operating systems and middleware for different products can select the jointly developed ADI-Green Hills solution and receive full tools support.   About ADI's Blackfin Processor Family   Based on the Micro Signal Architecture (MSA) jointly developed with Intel Corporation, ADI's Blackfin processor family combines a 32-bit RISC-like instruction set with 16-bit dual multiply accumulate (MAC) signal processing functionality with ease-of-use attributes found in general-purpose microcontrollers. Dynamic Power Management enables breakthrough power consumption by allowing the simultaneous adjustment of operating frequency and voltage under application control.   More on Green Hills MULTI   Green Hills Software's award-winning MULTI IDE automates all aspects of software development for a broad range of microprocessors. Featuring a window-oriented editor, RTOS-aware source-level debugger, and graphical program builder, MULTI also includes a run-time error checker, version control system, performance profiler, and real-time event analyzer (EventAnalyzer™). MULTI also features an instruction set simulator that allows programmers to develop and test Blackfin code on a PC or workstation without the need for the target hardware.   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. Green Hills Software's royalty-free INTEGRITY® RTOS, compilers, MULTI® and AdaMULTI Integrated Development Environments and Green Hills Probe™ offer a complete development solution that addresses both deeply embedded and maximum reliability applications.   Green Hills Software is headquartered in Santa Barbara, CA, with European headquarters in the United Kingdom.
