The company Jöhl + Köferli AG offers tailored radio-transmission solutions. Supplemented by a control system, a central communication infrastructure for public transport emerges.

The comprehensive and reliable radio coverage of an area is always hampered by topographical and structural barriers. The single frequency radio network technology designed by Jöhl + Köferli AG solves this problem by using many spatially separated base stations, which guarantee full coverage of the concerned areas. The base stations emit information, which is synchronised on the same frequency. Thus, the frequency spectrum is used economically, allowing the use of simple terminal devices.

The voice connection between the control system and the base stations is achieved via voice-over-IP. The GPS-based synchronisation, designed to keep a precision up to microseconds, allows the simultaneous emitting of the signal at all base stations.

Supercomputing Systems AG (SCS) has developed a universal hardware platform, which is used by the control system (TMC) as well as the radio transmission site (BSC). It is based upon a multi core ARM Cortex A9 processor and the Altera FPGA technology.

Moreover, the Linux software and the FPGA firmware have been developed for the Voice-over-IP communication, the FSK modems as well as the call decoder.

The platform can be used for the integration of a variety of other signal processing tasks.

Jöhl + Köferli AG use the module in a flexible and universal way and expand it according to the different requirement of the public transportation companies. Via a web-based configuration panel, adjustments can be quickly performed.

Wir demonstrieren ein Entwicklungssystem für Stereo-Kamera-Fahrerassistenzsysteme auf der Basis des Zynq All Programmable SoC. Optimiert für die Entwicklung von Bildanalysealgorithmen demonstriert dieses System sowohl eine Bildentzerrung als auch die Berechnung des SGM Stereo um die Lage und den Abstand von Objekten abzubilden.

SGM Stereo on SCS Zynq Box

EW2014

Modern cars are using more and more cameras in order to provide a better and more comprehensive display of their surroundings. Camera manufacturers need reliable measurement technology to design such systems. The SCS measurement technology box makes it possible to record and play back up to six LVDS cameras. The ‘Recorder System’ developed by SCS has been adopted by automobile OEMs and tier 1 companies for the development of cameras and surround systems.

Filters for EB Assist ADTF for recording and playing back are available, as well as a stand-alone GUI developed by SCS.

The system consists of the Spartan 6 FPGA card developed by SCS and a customised adapter card for the corresponding camera system. This allows precise hardware timestamps to be recorded and multiple cameras to be synchronised with each other. Furthermore, algorithms can be calculated directly on the FPGA in order to relieve the measurement technology computer. The data is transferred to the measurement technology PC via Ethernet connections.

Thanks to its system structure, SCS can adapt it very quickly to your Maxim, TI or National Semiconductor serialiser.

The JPEG IP core for FPGAs, developed by SCS, allows compressed Ethernet packages to be received and then decompressed. The decoder has been optimised for low consumption of resources for a Xilinx Spartan6 or Zynq FPGA and is already in use by an OEM and a tier 1 company.

The JPEG Decoder has the following properties:

  • Processing rate of up to 140 MSamples/sec on Spartan6 FPGA
  • 12Bit / 8Bit version available
  • Four Huffmann tables (fixed or extracted from header)
  • Up to 8 quantisation tables
  • Support to decode several interleaved image stripes
  • 3 color components
  • Support 1 scan configuration and YUV 4:2:0 (Different format on request)
  • Supports any image size up to 64kx64k
  • Supports restart markers

When the Swiss start-up company Limmex started selling the “Swiss Emergency Watch” in autumn 2011, it was the beginning of a success story. The innovative emergency watch combines various technologies to form the mobile emergency device of the future.

The availability of the switching platform and the long battery life are indispensable factors to the success of the product for Limmex’s customers.

The services provided by SCS include:

  • Advice on system architecture
  • Development of cloud-based services
  • Development of embedded software
  • Development of product test systems
