Smooth implementation of hard real time
It has been announced that congatec has teamed up with OSADL, Open Source Automation Development Lab, to optimise the board support for real time Linux and showcase it in the OSADL test racks.
In a first step, OSADL qualified congatec’s latest real time Linux implementation that uses Linux kernel 4.9.47-rt37 on conga-TS170 Server-on-Modules equipped with the embedded server class Intel Xeon processor (E3-1578L v5 at 2.00GHz). The COM Express Type 6 module mounted on the evaluation carrier board conga-TEVAL performed well in the tests, impressing in particular through real time capabilities.
The challenge when implementing hard real time Linux behaviour lies in mastering all processing layers from BIOS to Linux kernel to user space, since the overall real time capabilities are only as good as the weakest link in the chain.
In addition, modern processors such as Intel’s Skylake family offer a wide range of energy saving features that must be balanced to the requirements of real time computing. Executed in standardised racks, the OSADL quality assurance testifies that conga-TS170 Server-on-Modules are suited for any real time application.
Target markets for these high end modules for workstations and servers that also provide high end graphics include high speed test and measurement equipment, back-end systems in medical imaging, high performance industrial workstations as well vision based inspection systems and situational awareness platforms.
Dr. Carsten Emde, General Manager of OSADL eG, stated: “The congatec module with the Intel Xeon E3 processor of the Skylake generation passed all tests and showed excellent response times. We at OSADL are very pleased that congatec has joined our organisation. congatec and OSADL fit together very well; our customers and members come from virtually the same industries and therefore benefit equally from our services. One of these services is the OSADL QA farm, where embedded systems with very high test depths are tested for their real time capability and other features important for industry.”
Carsten Rebmann, Director R&D at congatec, added: “Teaming up with OSADL is a great advantage for both our customers and our own engineering team, as we all benefit from the joint forces for our real time Linux developments. OSADL membership provides a vendor independent testimonial of our high-quality engineering and we receive great support with licensing questions as well. Joint engineering projects for new open source solutions also help us to concentrate on our own core competences – offering competitive advantages for our customers by simplifying the use of embedded computer technology.”
congatec products support all major real time capable OS from both x86 and ARM technologies. These include first and foremost real time Linux but also further RTOS such as VxWorks or QNX, as well as deterministic hypervisor and visualisation technologies from vendors such as Real time Systems.
