Lineo sells these technologies to a wide variety of OEMs for such embedded solutions as internet TV set-top devices, internet kiosks, single board computers, point-of-Sale systems, hand held devices, low cost routers, network computers, small bootable OS solutions (ie. bootable CD-ROMs, floppies).
Lineo, Inc. is a subsidiary of Caldera, Inc., which was founded by Bryan Sparks in 1994. Caldera's business plan was to offer products based on the then-fledgling Linux operating system to business customers. In July of 1996, Caldera purchased the DR DOS business and all related DOS assets from Novell to market these technologies to embedded markets as well as integrate these products with the company's existing Linux product line. Caldera felt that offering a "thin client" to its Linux based servers was a sound strategy and DR DOS offered a well tested, stable and established technology base upon which to build these products.
In the summer of 1998, Caldera, Inc. created two separate companies to further focus the development, marketing and sales efforts of the company's two divisions: Caldera Systems, Inc. addressed its "Linux for Business" target, while Caldera Thin Clients, Inc. addressed the thin client embedded systems market.
In July 1999, Caldera Thin Clients changed its name to Lineo, Inc. -- to emphasize the evolution of the company's focus on the emerging embedded Linux market. The Lineo management team believes the company is the benefactor of a history with both Linux and embedded systems, focused industry partnerships and good timing. Bryan Sparks, founder of Caldera, Inc., is CEO of Lineo, Inc.

• Zentropic Computing

Born from the military simulation industry, where real-time computing is critical, Zentropic Computing, LLC (Zentropix, www.zentropix.com) was founded in August, 1997, and has offices in the US and UK. Zentropix was born from the search for a reliable low cost real-time operating system for a PC/DSP communications switching platform to be used initially by Advanced Simulation Technology inc., a US company well positioned within the military simulation market. After investigation into many viable alternatives, it was soon evident that the then developmental "RTLinux" from a group at New Mexico Tech held great promise. RTLinux included the framework for preemptive and deterministic operation within Linux while, at the same time providing the open source, low cost, high performance and stability advantages of Linux. To date, RTLinux has met expectations and has continued to grow into a much more capable and feature rich RTOS.
In mid-1999 Zentropix started working closely with the Dipartimento di Ingegneria Aerospaziale Politecnico di Milano (DIAPM) developers of the Real-Time Applications Interface (RTAI) for Linux. Similar in performance to RTLinux, the RTAI is implemented in a much less intrusive manner and provides an exceptional real-time development environment which is now comparable with many of the commercially available RTOS'.
Since its inception Zentropix has been actively working with the open source community by contributing features, testing, documentation, and development tools for real-time Linux (www.realtimelinux.org). We intend to continue this trend to bring quality RTOS features and services, development tools, training, and support to the industrial and embedded communities.
Zentropix provides four types of products and services:
• RealTime Linux Installation CD

The RealTime Linux installation CD for Linux 2.2 features a validated and tested installation of RealTime Linux, real-time Linux specific documentation, sample applications and test code, as well as Zentropix non-intrusive and step and trace debuggers for RealTime Linux.
Based upon Red Hat 6.0 and Linux kernel 2.2.10, this latest CD provides a one step installation for a complete real-time Linux operating environment based on either the RTAI version 0.7 made available under the LGPL by the Dipartimento di Ingegneria Aerospaziale Politecnico di Milano (DIAPM), or the New Mexico Tech RTLinux version 2.0 made available under the GPL from FSMLabs.
RealTime Linux provides guaranteed, hard real-time scheduling; yet retains all of the features and services of standard Linux. Additionally, it provides support for: Uni-Processor and Symmetric Multi Processor platforms, simultaneous one-shot and periodic schedulers, both inter-Linux and intra-Linux shared memory, FPU support, inter-task synchronization, semaphores, mutexes, RPCs and more.
Also included on the CD, are Zentropix debuggers specifically aimed at the real-time or kernel developer. The Remote Kernel Module debugger is based on the capable gdbstubs package, but also provides the host machine with the ability to step-and-trace the target's kernel modules by using the standard GDB debugger and a graphical interface such as DDD. The R2D2 debugger addresses later development stages when it is critical that the application is not "stopped" or "stepped" during debug. This debugger provides non-intrusive, run-time symbolic access to parameters within both user space and the kernel and its modules, while the parent task continues to execute at its normal iteration rate.
• RealTime Linux development tools and debuggers

Zentropix develops and provides tools which complement the standard Linux GNU tool chain.
Remote Kernel Module Step and Trace stub for GDB and the Remote Run-time Data Debugger (R2D2), as open source developments under the Gnu Public License. These tools for real-time Linux development have, until now, been missing from the Linux developer's arsenal.
The Zentropix Remote Kernel Module debugger is based on the capable gdbstubs package, but also provides the host machine with the capability to step-and-trace the target's kernel modules by using the standard GDB debugger and a graphical interface such as DDD.
Although existing tools such as GDB/DDD, and the Remote Kernel Module debugger cover an extremely important phase of the development cycle, the R2D2 debugger addresses later development stages during which it is critical that the application is not "stopped" or "stepped" during debug. This debugger provides non-intrusive, run-time symbolic access to parameters within both user space and the kernel and its modules, while the application continues to execute at its normal iteration. This powerful paradigm dramatically increases the speed and simplicity of application tuning, integration, and verification.

Because of the flexibility of Neoware's NeoLinux software and information appliances, developers are limited only by their imagination.
• QNX Software Systems

For more than two decades, QNX Software Systems has been responding to the complex needs of realtime embedded developers - needs like high reliability, realtime performance, sophisticated functionality, small footprint, and massive scalability. During that time, our flagship product, the QNX® RTOS, has evolved from the first-ever microkernel OS for PCs into the best-selling and most trusted OS for mission-critical applications.
QNX has always believed in open standards that are vendor-neutral and reflect the real-world needs of embedded developers. In fact, the new QNX realtime platform is engineered for the same industry-standard POSIX APIs that Linux has popularized today. And because QNX and Linux are so compatible, almost any Linux tool can be easily ported to and used with QNX, and vice versa. Open ... in all the right places To extend that open philosophy even further, we?re providing features like free availability, accessible source, and open architecture with our realtime platform. Free availability To begin with, we?re offering the full platform free for non-commercial use. So developers can download, evaluate, and create proofs-of-concept right away, effectively lowering their cost of entry. With this approach, we?re widening the community of developers familiar with QNX - and increasing the number of third-party products for QNX-based systems. The free download is available at get.qnx.com. Accessible source Besides making QNX free for non-commercial use, we?re also providing source code for most components - drivers, protocol managers, and so on. Only the kernel and other core portions of the QNX platform remain protected, giving OEMs the benefit of building their systems on secure technology with clear IP ownership. This best-of-both-worlds approach is possible due to the microkernel architecture of the platform?s OS. Most OS-level services exist as processes residing outside the kernel. So it?s relatively easy to extend the system - simply add or change OS components. Only new modules need to be tested, which saves time and improves overall system reliability. Open driver architecture Our open concept also extends to driver development. Only low-level components need to be modified, which makes it easier for third-party developers to write drivers. And there?s a huge community of developers who can write those drivers - since QNX supports industry-standard APIs. More than just another RTOS The QNX realtime platform is built on the QNX Neutrino® realtime OS, the most advanced RTOS on the market. QNX Neutrino enables the design of highly reliable, scalable, and deterministic systems. On this stable core of technology, we?ve added a customizable GUI and an integrated suite of production-ready components. The result? Everything needed to build reliable, realtime embedded devices - today. The QNX realtime platform features: development tools - popular command-line GNU development tools, graphical debuggers, and third-party development tools a graphical user interface - customizable, embeddable Photon micrGUI® windowing system makes it possible to bring professional, high-end graphics to even the smallest, memory-constrained device networking - from scalable TCP/IP connectivity to QNX Networking (QNET?), a message-based native networking protocol that provides distributed access to any resource, anywhere Internet technology - full-featured Voyager? browser lets you surf the Web or serve HTML pages in realtime multimedia technology - all the necessary plug-ins to create the most complete and dynamic multimedia experience possible, such as Dolby Digital AC-3, MP3, MPEG-1, MPEG-2, CD audio, and more Our alliances We are a realtime platform company, but we also know there?s more to the development picture than just having the right products. A complete solution is just as important. To cut our customers? time to market and make their products best of class, we seek out industry-specific functionality that complements our technology. We dedicate much time and effort to developing and nurturing strategic relationships with software and hardware manufacturers of all kinds - leaders in semiconductor technology, development tools, communications protocols, single-board computers, and so on. Our markets With our extensive experience in the embedded marketplace, we understand the special needs of value-added resellers and OEMs. As a result, we?ve established a firm base in many vertical markets, including medical instrumentation, telecommunications, consumer electronics, automotive computing, and industrial automation.

• TimeSys Corporation

TimeSys Corporation is the leading vendor of solutions designed to eliminate timing problems in, and enhance predictability of, real-time systems. TimeSys' set of end-to-end solutions for building predictable real-time systems includes analysis and simulation tools, profiling and visualization tools, as well as consulting, customization, and training services. The company's team of world renowned experts brings a unique blend of application experience and research expertise in domains such as telecommunications, automotive, defense, and process control to help companies solve real world problems. Overview In telecommunications, network systems, defense systems, aerospace systems, and embedded electronics such as medical and automotive systems, the consequences of system malfunction due to timing errors can range from significant loss of revenue and goodwill, to loss of life and property. It can also lead to degradation in predictability and performance. For example, an automobile airbag must deploy at precisely the right moment, in order to function properly. Should an airbag deploy a fraction of a second early or late, the results could prove disastrous. The rapid change and increasing complexity of these real-time systems, along with industry's growing dependence upon them, is placing extraordinary burdens on real-time systems engineers. TimeSys solutions address performance and predictability issues, thereby eliminating the risks of identifiable timing errors and shortening the product development cycle significantly. To solve the unique problems posed by real-time systems, TimeSys provides multiple integrated solutions. Using innovative concepts (commonly referred to as "Rate-Monotonic Analysis" - RMA) developed at Carnegie Mellon University (Pittsburgh, PA) and the Software Engineering Institute (Pittsburgh, PA), TimeSys offers a family of complementary products and related expert services. Products and Services TimeSys products and services offer important benefits to customers by eliminating system timing risks, reducing development time, reducing testing and integration time, and minimizing warranty expenses due to system malfunction. The company's complete spectrum of fully interoperable software products, re-usable libraries, training, customization, and consulting services is marketed under the SuiteTime banner. SuiteTime products and services include: TimeWiz -- a tool for timing analysis, simulation and modeling of single processor and distributed real-time systems including custom network protocols. It uses the popular rate-monotonic analysis (RMA) methodology for building predictable real-time systems, and can be readily customized and extended for other schemes as well. It also includes an API that enables the product to integrate seamlessly with custom analysis modules. TimeTrace -- measures and displays the exact execution sequence within a real-time target, and can also provide the execution time data needed for timing analysis by TimeWiz. This product has been applied to a number of popular real-time operating systems (RTOS). TimeSys Linux/RT -- A real-time version of the Linux operating system, and the first solution that extends the open-source kernel to provide predictable real-time response, entirely from the Linux operating system. Engineers can build hard real-time systems with this product, while enjoying the reliability and stability that have become the hallmarks of the Linux OS. TimeSys Linux/RT will be available at no cost via web download from TimeSys in April 2000. A real-time Java Virtual Machine -- TimeSys will release a real-time Java Virtual Machine that will run on top of TimeSys Linux/RT, and will comply with Sun Microsystems' Real-Time Java Specification. TimeSys is a member of Sun's Real-Time Java Experts Group, the body that is creating the specification. The product is scheduled for release in 3rd quarter of 2000. Custom Solutions -- A team of world class experts and application engineers from TimeSys works with customers to provide architecture and infrastructure services necessary to address timing issues. The solutions include technology training, software, tools, project-specific consulting and customization. TimeSys will also collect and analyze real-time system timing data. Corporate Expansion TimeSys has launched TimeSys Linux/RT to capitalize on the market's demand for an open-source strategy for embedded systems development. While TimeSys is confident that TimeSys Linux/RT will capture a sizable share of the market, the company realizes that real-time system developers must deal with and continue to support many legacy real-time systems and software products. Because of this, TimeSys' tools, expertise and technologies are also designed to function across many platforms, as evidenced by the company's alliances with multiple operating system vendors including Microsoft, Lynx, Sun, VenturCom, and Aonix. This cross-platform capability enables TimeSys to work with customers who have deployed heterogeneous real-time operating systems in their environment. For example, telecommunications vendors may use small-footprint operating systems like VxWorks deep within network elements, larger real-time operating systems like LynxOS for real-time reconfiguration, and VenturCom's RTX for Windows NT Embedded for management and statistics collection. TimeSys tools and services can provide support for such heterogeneous environments while offering an open-source path for new projects and developments. One-Stop Shop for Dealing with Timing Problems TimeSys adopts a two-pronged approach in developing and promoting its SuiteTime array of solutions. Since problems that manifest themselves in the integration phase or after deployment are very expensive to fix: TimeSys emphasizes capturing and analyzing timing requirements early and continuously; we provide a family of products, oriented around distinct product lines to support this philosophy. TimeSys uses established real-time resource management techniques codified in a "Handbook of Real-Time Systems: The Rate-Monotonic Analysis Framework" written by authors at the Software Engineering Institute. We provide expert guidance, consulting and training services based upon these principles and centered around the product families. Publications TimeSys has published a free booklet entitled The Concise Handbook of Real-Time Systems which has come to be known as the "pocket bible" in the real-time systems marketplace.

• ETLinux

Etlinux is a complete Linux-based system designed to run on very small industrial computers. It has been designed to be small, modular, flexible and complete. Its reduced memory and disk requirements make it ideal for all cost-sensitive situations, while at the same time its modularity and completeness give the full power of unix even for embedded applications.
Etlinux is ideal in all embedded system applications where advanced unix facilities are a must: preemptive multitasking, multithreading, memory protection, fast I/O, enhanced reliability, speed, ... Moreover, source code availability is a guarantee for the longevity of Etlinux based products. But perhaps the greatest advantage over competitors is given by the enormous and proven availability of advanced development tools, documentation and sources, giving an effective edge to the developer and reducing the time to market. In fact the availability of constantly updated quality C/C++ compilers, debuggers, libraries, interpreted languages, and other tools is the most compelling reason to switch away from old proprietary embedded development environments.
Some features of Etlinux: embedded cgi-capable WEB server, a telnet server, an email server (with the ability to execute commands sent by email from a remote site), CORBA support, remote file management, Tcl scripting language, and a flexible package selection scheme.
Etlinux requires an Intel-compatible 386SX processor (or better), 2MB of RAM, 2MB of disk (HD or M-Systems DiskOnChip).
Etlinux development has been sponsored by EuroTech Spa (http://www.eurotech.it), in order to have a reliable Operating System for their own embedded PC/104 systems. Although Etlinux includes device drivers for EuroTech peripherals, it is pretty general, and can run on almost any Intel 80x86 based industry standard PC.
