IS YOUR PROCESSOR INNEED OF A REAL-TIMEM U L T I - T A S K I N GOPERATING SYSTEM?

If you answered YES to any of the abovequestions, you would certainly benefitfrom considering an RTOS for your appli-cation.

In some cases, well structured linear pro-gramming is sufficient for a product. Inmost cases, however, programmers appre-ciate not having to worry about structur-ing their code to perform all necessarytasks in a timely manner. This is whereCMX-RTX can help. CMX-RTX allowstasks (pieces of code that do specificduties) to run quasi-concurrently. Thismeans that tasks will seem to run all at thesame time - doing many specific jobssimultaneously.

CMX-RTX takes the worry and headachesout of real time programming. Our soft-ware lets you concentrate on the overallapplication while taking care of the littledetails for you. Finish your projects fasterand more efficiently with CMX-RTX inyour programmer's toolbox!

CMX-RTX offers a truly preemp-tive, multi-tasking operating system.

WHAT DOES TRULYPREEMPTIVE MEAN?

Some RTOS vendors offer only coopera-tive scheduling which means that the run-ning task has to call the scheduler to per-form a task switch. Others offer time slic-ing in which each task runs for a certainperiod of time at which point a task switchtakes place no matter what. Other vendorsclaim to be fully preemptive, yet they donot allow any interrupt to cause a preemp-tion. All of these models will fail you atone point or another.

CMX-RTX allows a task of higher priori-ty that is able to run (whether starting orresuming) to preempt the lower priorityrunning task. This will cause the sched-uler to save the context of the running(lower priority) task and restore the con-text of the higher priority task so that it isnow running. A truly preemptive RTOSallows interrupts to cause an immediatetask switch. This means that the interruptsnow have the added ability of using theRTOS's functions and causing an immedi-ate context switch if needed.

NOT ALL REAL TIMEOPERATING SYSTEMSARE CREATED EQUAL!

CMX-RTX is a powerful RTOS thatuniquely provides:

The smallest footprintThe fastest context switch timesThe lowest interrupt latencytimesTrue preemptionScheduler and interrupthandler written in assembly forspeed and optimizationOptional co-operative and time-slicing schedulingNested interruptsAll functions contained in alibraryInterrupt callable functionsScalabilitySeveral C vendors supported

CMX technical support is renownedthroughout the world. Average wait timesfor a tech support person is under oneminute and over 95% of our calls areresolved over the phone! If a questioncannot be resolved over the phone, theanswer is usually found and relayed to thecustomer within hours.

Our philosophy also includes giving theengineer all of the source code to the prod-uct. This is not only an invaluable debug-ging tool, but dramatically reduces thelearning curve associated with any RTOS.It also allows for smaller code sizebecause only functions that are used arelinked into the final output module.

Does your processor control theway you program?

Do you spend too much time fig-uring out how to make a sectionof code execute when it needsto?Do you constantly have to testflags (or go to routines that test)to see if you should execute acertain function?Do you spend too much timewith interrupt routines whiletrying to write the code neces-sary to process the interrupt'sevent because the main codewould not get to it in a timelymanner?

WHAT IS CMX TCP/IP?

CMX TCP/IP is a portable, high perfor-mance TCP/IP implementation for embed-ded systems. Memory usage is localizedand deterministic. CMX TCP/IP usesRTOS signaling mechanisms to provide atrue, multi-tasking re-entrant networkstack. When no RTOS is available, CMXTCP/IP provides a straight forward, singlethreaded stack that supports multiple sock-ets via the select multiplexer. The systemhas a simple and familiar programmingAPI, including standard sockets andcallable application modules.

CMX TCP/IP is the only solution that youwill need for embedded applications. It isembedded in set top boxes to connectthousands of homes to the internet throughtheir cable TV provider. It links thousandsof sites to a home office for interactive,satellite-based training. It connects instru-ments to a PC or workstation over ether-net. It links gaming tables and industrialcontrollers on LAN's to host computers.

CMX TCP/IP is sophisticated enough tohandle the toughest wide area networkingjobs, but is still compact and economicalenough to be used in a simple LAN appli-cation. CMX TCP/IP's low cost, cleanimplementation, and high functionalitymake it a breeze to add TCP/IP network-ing to any application.

The CMX-Tiny+ real time multi-tasking operating system is an extremely "lean and mean" kernel that providesan optimized, small footprint solution for 8-, 16-, 32-bit processors with limited RAM. This specially designedRTOS allows the user to develop application code that is run under an RTOS and yet only use the onboardRAM that the processor provides! CMX-Tiny+ does not need any external RAM, regardless of whether theprocessor can support the use of external RAM or not.

CMX-Tiny+'s code size is so small that it allows the processor's onboard FLASH to support both the user'sapplication code and the CMX-Tiny+ code, in most cases. This unique RTOS, based on a scaled down versionof the popular CMX-RTX™, retains most of the power of CMX-RTX as well as the more frequently used func-tions. CMX-Tiny+, a truly preemptive RTOS, also provides support for cooperative scheduling, if desired.CMX-Tiny+ also is integrated with the CMX-MicroNet™ TCP/IP stack for those applications requiring net-working connectivity.

Embedded systems engineers have long desired the ability to view their programming applications running under an RTOS via their In-Circuit Emulators and Simulators/ROM monitor debuggers. To meet this important need, CMX has developed CMXKAware whichintegrates seamlessly with a number of the leading emulator manufacturers' and/or C vendors' simulators/ROM monitor debuggers. Theresult is a dramatically enhanced debugging capability that will help to minimize application development time, thereby reducing timeto market for companies that manufacture products which include embedded systems.

CMXKAware is an Active X object, DLL or ORTI (OSEK Run Time Interface) that presents all of the RTOS-specific information onthe screen. CMXKAware allows you to display CMX-RTX's internal data structures in a convenient series of lists in the RTOS windowof the debugger. This provides you with information about each of the active tasks in the target application, about each semaphore,resources, mailbox, queue and event flag group along with a list of all the tasks waiting on these kernel objects, and more. Data canbe displayed graphically in real-time.

The new OSEK Run Time Interface (ORTI) for CMXKAware is a universal interface for development tools to the CMX-RTX RTOS.This powerful and flexible interface allows for the evaluation and display of information about CMX-RTX, its state, its performance,the different task states, the different operating system objects etc. The object information is provided via an ASCII text file and sincethese implementations are configured statically, this data will be available at compilation. Additionally, the ORTI file contains dynam-ic information as a set of attributes that are represented by formulas to access corresponding dynamic values. Formulas for dynamicdata access are comprised of constants, operations, and symbolic names within the target file. By performing a continuous scan of theinternal data structures described in the ORTI file, debugging tools can extract and display critical kernel-relative information, such astask states and event traces for the last four RTOS calls in the application under test. Further, the CMXKAware ORTI Builder (seegraphic below) automates the creation of ORTI files adapted to the CMX-RTX RTOS for debugging purposes, thereby allowing embed-ded engineers to focus their efforts exclusively on debugging their application.

Since the OCX, DLL or ORTI utilizes the emulator or simulator kernel aware API, no target resources are used, as in the case withCMXBug (shown on another page). Most emulators and simulators/ROM monitor debuggers are supported. Please contact CMX fora complete list of supported platforms.

CMX-USB-CDC-ACM - This Class driver provides a CDC class implementation for supporting standard commports. An API is provided which allows the comm port to be either virtual in your embedded application or connect itto a serial port on your embedded design. Provided is a sample application, which has an embedded command lineterminal which can be accessed by the standard Windows terminal program (e.g. HyperTerm) through a Comm portover USB interface.

CMX-USB-MTP - This Class driver provides the Windows XP/Vista compliant Media Transfer Protocol (MTP)widely used in the design of portable media devices. This class driver option and Mass Storage alternative, appears asa standard drive to the host and can also be used with CMX-FFS file systems to provide synchronized device/ hostfile system access as well as API controlled file system access.

The CMX-USB-RFI - This Class driver is a Windows XP/Vista compatible alternative to Mass Storage andMedia Transfer Protocol (MTP). CMX-USB-RFI provides improvements to Mass Storage including the ability to syn-chronize PC and embedded application access, and the ability to incorporate a file system with greater reliability thanavailable with FAT. The CMX-USB-RFI device driver is provided at no charge with the purchase of the CMX-USB-RFI Windows Driver software.

CMX-USB-RNDIS - This Class driver is a USB virtual Ethernet driver with a simple API for easy integrationwith any TCP/IP stack or Ethernet driver interface. RNDIS Class allows the embedded target to appear as a standardnetwork card to the host allowing access to the target from a directly connected PC or from devices sharing the samenetwork.

Window Drivers

CMX-USB-RFI - This windows driver is a Windows XP/Vista compatible alternative to Mass Storage and MediaTransfer Protocol (MTP). CMX-USB-RFI provides improvements to Mass Storage including the ability to synchro-nize PC and embedded application access, and the ability to incorporate a file system with greater reliability thanavailable with FAT. The CMX-USB-RFI device driver is provided at no charge with the purchase of the CMX-USB-RFI Windows Driver software.

Bootloaders

CMX offers a variety of Bootloaders all of which are installed as fixed boot stubs in the target processor. Based on thedevelopers' trigger mechanism, the bootloader will check for a new code image. If available, the bootloader will pro-gram the image into the device. Specific Bootloader variants include:

CMX-USB-BL - Used to configure a bootloader that loads a new code image from a host (PC) application over aUSB connection.

CMX-USBH-BL - A standalone boot stub that can read a new code image from any USB pen drive, and use it toupdate your target device's firmware safely.

CMX-FAT-BL - Checks an attached SD card (or other similar media) for a new code image and if available, pro-grams the image into the device.

CMX-CANopen implements the CANopen protocol stack as defined by the CiA (CAN in Automation manu-facturer's group) Draft Standard "CANopen Application Layer and Communication Profile" DS301 version4.02. Although primarily intended for the usage in CANopen slaves, the code can also be used to implement aCANopen NMT Master (Network Management Master). Code examples provided have been tested with andpassed the official CANopen conformance test.

CMX-CANopen can be used both as a stand-alone product as well as a communication stack for the real-timeoperating system CMX-RTX. When used with CMX-RTX task priorities can be adapted to best suit the needsof a particular application allowing to assign different priority levels to different process data messages.

Many define statements are used to enable and disable CANopen features, allowing for a very high-level ofcustomization. Single transmission types can be selected to only include those transmission types that are actu-ally used in the application.
