The RTOS Motto: On Time And On Budget

The RTOS Motto: On Time And On Budget
But is an RTOS always necessary? The answer is application-specific, so understanding what one will deliver is key to determining whether it becomes a requirement or an extravagance.
In general, an RTOS can be used anywhere a non-RTOS is employed. However, it’s rare to find an operating system with a matching RTOS that has exactly the same application programming interface (API). Many of them, though, embed an RTOS within a conventional operating system. For example, Lynux- Works LynxOS and Bluecat Linux share a Linux API. LynxOS is a hard RTOS, while Bluecat inherits its base from Linux.
Linux continues to improve its real-time performance, but its worst-case interrupt latency still doesn’t meet what would be considered hard real time for an RTOS. It all comes down to quality of service (QoS). Platforms like RTLinux Free augment Linux, providing hard real-time class QoS.
It’s important to note that this type of addition often incorporates an RTOS programming environment that’s distinct from the original operating system. An RTOS is typically small compared to a conventional desktop or server OS. They often target more smaller, resource-constrained microcontrollers. For instance, CMX’s CMX-RTX and CMX-Tiny+ can run on 8-bit MCUs up through 64-bit processors.
The increased power and memory capacity of 8-bit processors is making an RTOS more desirable for these platforms. But, an OS or RTOS is usually a requirement in 16-bit platforms and up with RTOS products like Express Logic’s ThreadX, Wind River’s VxWorks, Micrium’s uCOS-II, and Green Hills Software’s velOSity being common selections. Depending on requirements, MontaVista’s Linux meets 16- and 32-bit platform requirements in the low microsecond range.
Most programmers aren’t familiar with RTOS constraints and requirements. Most usually opt for an RTOS due to its performance. Most RTOS products are small and fast, yet an RTOS also adds consistency. Beyond the fact that an RTOS gets the job done quickly, it can guarantee a job will get done.
In many applications, a late result can be catastrophic. Thus, a poor result within the proper timeframe is preferable. These applications are generally called hard real-time systems. Hard real time doesn’t indicate how fast the system may be or how quickly a system may respond. Rather, it refers to how reliably a system can meet the specified requirements.
A hard real-time system may have a fixed cycle time of one minute with a response time of one second. In theory, it’s something almost any operating system could handle. This isn’t always the case, though, as anyone can attest to when waiting for a desktop application to respond within a minute.
Hard real-time systems typically have shorter cycle times and tighter response requirements. Faster processors always help, and multicore platforms can improve response time, too. The trick for developers is to match system requirements to the hardware and software, hence the importance of an RTOS in embedded applications.
An RTOS can implement a range of scheduling policies, and the application will often restrict a programmer’s choices (see the table). Non-preemptive scheduling is trivial to implement but useful in some applications. On the other hand, non-preemptive scheduling within a task can be implemented on top of a preemptive system.
Non-preemptive should not be overlooked, especially in light of new multicore processors. Here, hardware may be tuned to handle an event-based operation in which a thread will wait for an external event to occur. This approach is usually unsuitable for a single-core processor handling multiple threads. On multicore systems with many cores, though, it’s often typical to dedicate one core to handle one peripheral. It then makes sense to have that core idle while waiting for an event to occur.
As a result, preemptive, interrupt-driven RTOS architectures make up the majority of platforms deployed. These platforms have a range of requirements, issues, and solutions (see the figure). Interrupt latency is always an issue, although hardware— multiple register sets, hardware scheduling and task switching, and hierarchical priority interrupt systems—can significantly reduce this overhead.
Several issues coincide with preemption. Most are timing-related, like race conditions, deadlock, starvation, and priority inversion, which occurs when a low-priority task A owns a synchronization resource of a higher-priority task B, and a task C with priority higher than A is running.
Without a feature like priority ceilings, task C can prevent task A and C from running. A priority-ceiling feature changes the priority of task A to that of task C, allowing it to run and eventually release the resource needed by C. At this point, task A’s priority returns to normal and task C can run.
The other timing-related issues, which the programmer must address, are often the sources of bugs that are difficult to locate and correct. Trace tools become valuable assets in locating these kinds of bugs, since symptoms such as blocked tasks are the only indication of the problem

VSEP Membrane Cleaners In addition to filtration systems, New Logic manufactures a complete line of chemical cleaners designed to maintain maximum flow rates in all VSEP applications.Years of exhaustive research and development by New Logic engineers have resulted in seven chemical cleaners formulated to attack the most stubborn foulants across a wide range of membranes and feed streams.While designed for VSEP membrane filtration systems, these advanced formulas are perfect for cleaning any membrane.To learn more about VSEP Advanced Cleaning Solutions, please choose a link below to visit our sister site

While membrane-based separations of liquids from solids have enjoyed increasing popularity over the last 20 years, the technology has an inherent Achilles heel that affects all membrane devices: fouling. This long-term loss in throughput capacity is due primarily to the formation of a boundary layer that builds up naturally on the membranes surface during the filtration process.In addition to cutting down on the flux performance of the membrane, this boundary or gel layer acts as a secondary membrane reducing the native design selectivity of the membrane in use.EMERYVILLE, Calif. and IPSWICH, Australia, Sept. 21 /PRNewswire/ -- New Logic Research, Inc., the maker of VSEP, the vibrating membrane filtration system, announced today its participation in the official commissioning ceremony for the Australian Hardboards Water Recycling Plant in Queensland, Australia.On hand for the ceremony were members of the Australian Hardboards and New Logic executive team, as well as numerous business leaders and local officials, including Cr. Paul Pisasale, the mayor of Ipswich.The wastewater treatment and recovery system, which combines seven i84 VSEP nanofiltration membrane modules, recovers wastewater for reuse within the plant. The system, which is capable of processing approximately 200,000 gallons per day, runs continuously automated by a programmable logic controller (PLC).According to New Logic CEO Greg Johnson, "VSEP is fast becoming accepted as the best available technology for tough wastewater treatment applications in Australia. The Australian Hardboards installation represents our second Australian installation in as many months; still more will be coming online within the next year. We were honored to be a part of the ceremony, and to show our commitment to helping to solve the Australian water shortage problem."New Logic International Sales Manager Melysa Reiss adds, "The paradox of Australia's decreasing water resources and increasing industrial demand requires innovative technologies to bridge the gap. We are proud to have the opportunity to do just that for Australian Hardboards and other firms throughout the continent."Water shortage caused by drought and increased populations has created a crisis in many parts of Australia. Water supply levels have fallen to 30% of normal, and continue to drop. Local water districts have implemented severe water restrictions to try to stop the drop in supply levels. Brisbane is currently at a Level 4 water restriction that requires mandatory conservation. By recycling its wastewater and reducing its fresh water intake using the VSEP system, AHL has conserved the equivalent of 2000 homes worth of water supply per year. This example of water conservation is being used as a showpiece for other industries to follow.About New Logic Research, Inc.Headquartered in Emeryville, California, New Logic Research is the leading provider of high-performance membrane filtration systems used in a wide variety of applications from pure water and wastewater treatment to chemical process clarifications.

OMA-300 UV-VIS Get a quote Brochure Process Analyzer (ultraviolet-visible)

Sampling System
A window into your process.
The OMA-300 is our flagship analyzer, the cornerstone of AAI technology. This system is tailored to a variety of applications by virtue of its fundamental design. The nova-II spectrometer houses 1,024 photodiodes, each continuously measuring a distinct element in the UV-VIS spectrum. Ultra-fine wavelength resolution delivers flexibility; the OMA full-spectrum advantage is enormous selectivity for species absorbance range and robust background correction.

The OMA-300's field reputation for stability and automation made AAI engineering into a premiere global brand.

NOVA-II Spectrometer


The heart of the OMA analyzer series is the nova-II spectrometer. Its diode array contains 1,024 photodiodes, each designated to detect a specific wavelength. Collecting light intensity data from all these diodes simultaneously, the nova-II continuously produces full, high-resolution spectra of sample absorbance.

In engineering a spectrophotometer, higher light transmittance means more robust data. This was our guiding principle in designing the nova-II; we set out to achieve maximal light throughput while retaining an extremely stable, solid state build. The use of a dispersive holographic grating erases the need for multiple focusing mirrors (as found in Czerny-Turner models). Having fewer reflective elements reduces both stray light and incident light loss--manifesting as a very high signal-to-noise ratio.
