10 9 Our Competition VxWorks pSOS WinCE Linux Windows NT BeOS

11 Platform OSs Run on friendly desktop environments and are a nightmare to move to embedded environments. (Linux, Windows NT, BeOS) Operating Systems Live in One of Two Disjoint Worlds RTOSs Run on unfriendly embedded environments and are cross-developed on platform OSs as hosts. (VxWorks, pSOS, WinCE)

12 QNX is unique in that it runs great on both. Platform OSs Run on friendly desktop environments and are a nightmare to move to embedded environments. (Linux, Windows NT, BeOS) RTOSs Run on unfriendly embedded environments and are cross-developed on platform OSs as hosts. (VxWorks, pSOS, WinCE)

13 NeutrinoPhoton Tools Applications The QNX Realtime Platform

14 Programmers code to specific OS APIs. Two APIs have inertia and momentum. QNX is POSIX. More importantly QNX aligns itself with Linux in interpretation and extensions. Source code portable today. Binary RSN. APIs

15 14 Why Choose QNX over VxWorks A self hosted development environment is more productive –We also provide cross-devopment (Windows, Solaris) We conform to the POSIX standard –VxWorks is proprietary We provide a far more advanced OS architecture –Microkernel design –Full process model MMU protection (not a hack) We have capabilities which give us key advantages –Qnet networking –Photon MicroGUI

16 Memory Protection Comparison Real-time Executive (VxWorks) Monolithic Kernel (NT/ LINUX) True Microkernel (QNX) Application Device Drivers TCP/IP Stack Application Device Drivers TCP/IP Stack Filesystem TCP/IP Microkernel Device Driver Kernel space User space Kernel space Application User space

17 16 Why Choose QNX over Linux? Embedding is hard stuff –We are embedded experts with 20 years experience –The new embedded Linux companies have no experience Embedding is an OEM business –OEM sales are the cornerstone of our business We have clear IP ownership of all core OS modules We have capabilities that give us key advantages –Qnet networking –Photon microGUI ® We have a proven business model

18 Extreme Business Models

19 Provide a business model to allow for both freeware and commercial use Success Lies Between These Two Extremes

20 19 Increasing Mind Share (QNX is out there) Embedded systems hide the OS OEMs keep to themselves Because of this Product managers often have to sell QNX to management and their customers QNX lacks a cohesive community of developers QNX remains the secret of a select few

21 Give it away for free (get.qnx.com) or provide a low cost CDROM CostAvailability WEB download (hassle free) Installation Small download No need to repartition Four minute install Windows / Linux friendly Automatic hardware detection Removing Barriers to Entry

22 21 Barriers to Exit Getting developers to download QNX is only 1/2 the battle. Success is getting them to stay with QNX.

23 Enough tools and apps so you dont have to leave. It needs to be cool.

24 … not a toy version Barriers to Exit Developers want the real thing...

25 24 Support the community but more importantly… Allow the community to support itself Web-based support –knowledge database –special news groups –automatic and real easy updating of products Well-documented driver kits and published source code –drivers –libraries –applications –... Barriers to Exit

26 25 Barriers to Exit Open Source much of QNX Allows developers to better customize or tune the system. Shows by example how things work. Allows developers to avoid or overcome bugs in components that they didnt write. Source Code gives developers control over their lives. It makes them happy and in most cases more productive.

27 26 Why this is good for QNX Enthusiasts will play with it free at home –Some will be in a position to recommend it at work –Some will develop applications and drivers Engineers at work will be able to use QNX to prototype systems without getting cost approval –A working prototype shortens the sales cycle Our OEMs will become part of a community More developers which enables –more drivers –more applications –more consultants –more mind share

28 27 Why this is good for our OEMs More experienced engineers available More applications and drivers available More tools available QNXMore brand name recognition for their chosen OS - QNX

29 Seed the world with QNX. Our Goal is Simple

31 Networked and Distributed Disk Fsys CDROM Fsys Audio App TCP/IP Microkernel Photon GUI QNET App QNET Microkernel Messages flow transparently through QNET from one message bus to another. All applications and servers become network distributed without any special code.

32 Microkernel Architecture Disk Fsys CDROM Fsys Audio App TCP/IP Microkernel Photon GUI - Each process lives in its own memory protected address space - Drivers, Filesystems and protocol stacks are just processes which create names in the pathname space and accept messages (servers) - They may be started and stopped dynamically. - Processes communicate using messages open(/dev/ser1,..)sends a message to the serial driver process read(fd, …)sends a message to read data - Applications send messages to servers (clients) - Process may share memory using the standard POSIX mmap calls

33 32 QNET - A Fully Distributed Environment It seamlessly connects computers. Messages flow transparently between computers. Resources become network distributed. Applications can access these resources without any special code. The network can be –in a box (backplane) –over a LAN (wired and/or wireless) –over the internet

46 45 Telecoms & Datacoms High Availability Through Advanced OS Architecture Your system is no more reliable than the base upon which it is build

47 46 QNET for Telecoms/Datacoms Systems are networked together and do not share memory. Each system runs its own operating system and applications. A fault in one system will not directly effect the others. Networking is inside the box PCI backplane, internal switching fabric LinecardLinecardLinecardControlcard

48 47 QNET for HA Applications Load Balanced Distribution Data is sent out the link which will deliver it the fastest. This is be based upon link speed, queue length for each link. LinecardLinecardLinecardControlcard

49 48 QNET for HA Applications Ordered Distribution Data is sent out a primary link. If it fails data is diverted to a secondary link. The primary link is probed and when it comes back online data is diverted back to it. LinecardLinecardLinecardControlcard

50 49 QNET for HA Parallel Distribution Data is sent out both links at the same time. A failure on one link will not cause a stutter. LinecardLinecardLinecardControlcard

51 50 SMP Support PPC 604, 750, 7400 Pentium I, II, III One copy of the kernel runs on all processors and it and all applications share memory.

52 51 Fault Tolerant Distributed and SMP You can build massively scalable, high performance, fault tolerant systems by combining SMP in a distributed system. LinecardLinecard Controlcard
