The work has been roughly split into three research groups: memristive devices, CMOS design and system architecture, and industrial use of the ULPEC’s technology.
All partners have strongly been involved in the project, including large industry (IBM & Bosch) and innovative SMEs in the field (Prophesee & TSST). The key technology results of ULPEC include:
-A System-On-Chip (SoC) with a visual sensor array has been designed, fabricated, validated and tested. The visual sensor has been embedded in a HERMES chip with the final SoC containing the vision sensor, a Digital Control Block, 784 pre-synaptic and 100 post synaptic neurons and a ball pads array for memristor crossbar flip-chip. The flip chip assembly is much smaller than a traditional carrier-based system as the chip sits directly on the circuit board, and is much smaller than the carrier both in area and height. This allows to reach the ULPEC target in small chip size.
-A FEMR device technology suited to fabricate a spiking neural network.
With this work ULPEC demonstrated a manufacturable integration route towards the target SoC comprising the analogue vision sensor and the FEMR array.
Two training databases were developed and made openly accessible for algorithm development in traffic event detection. To the best of our knowledge, the databases are the largest and most comprehensive of their kind.
Besides the technology achievements, a detailed analysis of the advantages and limitations of ULPEC technologies was performed with a resulting list of most promising applications and an Exploitation Road Map. Both intend to provide the wider expert community with suggestions and strategies how academia, industry, and policy makers in Europe should proceed to achieve the greatest possible success. A special focus was put on future applications of high societal and socio-economic impact. The exploitation road map was complemented by dissemination, communication and stakeholder engagement activities and formats to maximise ULPEC impacts. Formats included two Policy Briefs, an open online course for training and skills development, and a number of ULPEC fact sheets in easy-to-understand language for the wider public.
