Research Fellow opportunity in the Directorate of Technology, Engineering and Quality. ESA is an equal opportunity employer, committed to achieving diversity within the workforce and creating an inclusive working environment. Applications from women are encouraged. Post Internal Research Fellow Postdoc in OnBoard Data Processing This post is classified F2 on the Coordinated Organisations salary scale. Location ESTEC, Noordwijk, The Netherlands Description Onboard payload data processing work is based in the OnBoard Payload Data Processing Section in the Data Systems and Microelectronics Division at ESTEC. Our competences include Data processor architectures Data acquisition chains High speed onboard networks Digital signal processing, processors and specialised devices Payload data storage Image and signal processing algorithms Data compression techniques High rate data encryption As part of ESAs Directorate of Technical and Quality Management, the Section provides technical support in its domain of competence to all programme directorates in order to support their missions and developments. The Section is also responsible for initiation and execution of technology developments that may lay the foundation for future missions. This comprises developments in analogue and digital hardware from components to subsystems and building blocks, lowlevel software and novel signal processing techniques. In particular, the Section hosts the centre of expertise for data compression algorithms, techniques and devices. It has initiated the development and standardisation of SpaceWire and SpaceFibre links, nodes and networks which have become very widely used not only in nearly all European space missions but also in the US, Japan, Russia and around the world. Interested candidates are encouraged to visit the ESA website for more information regarding the Divisions activities. Fields of activitiesresearch This research fellow position provides an opportunity for interested researchers to enhance the understanding of how reconfigurable spacequalified and COTS FPGAs, such as Microsemi RTG4 flashbased, Xilinx Virtex Zynq and ESAs BRAVE SRAMbased, can be implemented in current and future on board data processing units in an efficient way. While the fault tolerance of such devices is a rich research topic on its own, the research will be focused on how these devices are best used from a system engineering perspective, including The upload of full bitstreams to the spacecraft and the partial patching of bitstreams, including an investigation of possible compression schemes for interplanetary missions with lowspeed upload data rates The storage of bitstreams in memory, including an analysis of the optimal location and the required mechanisms e.g. to load the bitstream from a mass memory unit to the working memory of the payload instrument, to verify the correctness of the transfer and to execute scrubbing of the memory, if required The full and depending on the device technology partial configuration of the FPGA depending on mission phases or processing tasks to be performed. This crucial step requires special attention to ensure that neither the device itself nor any attached device is harmed due to a faulty configuration. An analysis should show up potential risks e.g. accidentally reprogrammed InputOutput blocks and suggest fault isolation schemes on unit level Even if it is known that the bitstream is downloaded correctly to the FPGA device, it would be interesting to execute some basic hardware validation before operation. For instance, the implemented hardware could be tested in flight, by stimulating it with test vectors on its inputs and by comparing its outputs to a known signature. It could be researched how to store and compress the vectors efficiently and how to write and read them tofrom the device JTAG boundary scan, NAND tree etc. A boot loader concept that implements similar to a software boot loader TMTC functionality to execute the abovementioned steps upload, download, decompression, memory copy, memory verification, full and partial reconfiguration of the FPGA, verification of correct functionality of the FPGA. The boot loader should also take into account i systems with multiple FPGAs, and ii systems that use the FPGAs as accelerators i.e. that want to dynamically request the installation of new hardware blocks from a main software running on a microprocessor. A tradeoff study could reveal the pros and cons of implementing this boot loader i external to the instrument, e.g. within the onboard computer, ii within the instrument in a dedicated microprocessor and iii even within the FPGA itself in either a hard or soft microprocessor.
