  • OPARO
    In the development of integrated, programmable circuits, the optimization of power dissipation and temperature distribution is becoming increasingly important. So far, however, these can only be determined by very time-consuming simulations. Therefore, precise models for the determination of power dissipation shall be developed and mapped together with the functional emulation on FPGAs. By accelerating the determination of power dissipation and temperature distribution, specific optimizations of the architecture and the application code can then be made taking real input data into account.

    Stochastic computing has recently emerged as a promising approach for designing energy-efficient embedded hardware systems, taking into account the ability of many applications (e.g., computer vision) to tolerate the loss of precision in the computed results. Rather than designing the hardware for worst case scenarios featuring expensive guard-bands, designers can relax the implementation constraints and deliberately expose hardware variability, obtaining significant processing performance improvements and energy benefits.

  • Design of a Configurable, Massive-Parallel Vector Processor Architecture for Computer Vision and a Framework for the Implementation of Object Recognition Applications for Embedded Systems
    The increasing complexity of current computer vision algorithms for autonomous driving, such as object detection and classification using neural networks, represents a challenge for automotive system designers. Providing a real-time processing system under hard real-time constraints and a low energy (budget a few watts) is difficult to achieve even with current technical platforms. The goal of this project is to design a new approach of application-specific vector processor for FPGA implementation. The well-known overhead of other platforms (e.g. GPUs) shall be avoided by using several strategies: Novel functional mechanisms, a modular and customizable architecture and a suitable development framework, which is especially designed for the implementation of automotive applications.). An FPGA-based prototype will demonstrate the performance of the vector processor concept for a selected application at the end of the project.

  • TETRACOM
    Nowadays, continuous development of digital signal processing applications, e.g., video-based advanced driver assistance systems, are pushing the limits of existing embedded systems and are forcing system developers to spend more time on code optimization. These applications often involve complex mathematical functions like trigonometric, logarithmic, exponential, or square root operations. In particular, these functions can only efficiently be computed on standard general purpose embedded processors, using highly optimized, processor specific arithmetic evaluation software libraries. Another alternative is to extend the embedded processor architectures with a specific hardware accelerator.

  • OPARO
    In the development of integrated, programmable circuits, the optimization of power dissipation and temperature distribution is becoming increasingly important. So far, however, these can only be determined by very time-consuming simulations. Therefore, precise models for the determination of power dissipation shall be developed and mapped together with the functional emulation on FPGAs. By accelerating the determination of power dissipation and temperature distribution, specific optimizations of the architecture and the application code can then be made taking real input data into account.

  • Compact Realtime SAR-Image processor
    The goals of this project are the generation and compression of high resolution Synthetic Aperture Radar (SAR) images under real time conditions. Compared to camera based electro-optical sensors, a SAR system operates almost independent from daylight and weather conditions. State-of-the-art SAR sensor systems achieve spatial resolutions up to 10 cm at 10 km altitude. By using FPGAs for high performance digital signal processing tasks, aerial images can be generated in real time even in case of very large image dimensions.

    As part of the BMWi-funded joint project ifuse, algorithms and architectures for the fusion of raw sensor data at a low level of abstraction are being investigated. Compared to previous fusion methods at the object list level, sensor data fusion at the raw data level enables more robust classification of objects and detection of the vehicle environment, even if individual sensors are impaired by environmental influences. Sensor data fusion at the raw data level is based on signals from active and passive vehicle sensors (e.g., LIDAR, RADAR, camera, ultrasound), which, after minimal preprocessing, are referenced to a common coordinate system and located in an environment model.

    The project "GreenML" aims to exemplify a holistic AI design process by the highly efficient and resource-optimized implementation of essential FAS functions like object detection, object classification, and scene contextualization on particular hardware. Deep Learning (DL) has become a central approach for modern AI applications. Even though energy-efficient DL has become a target in research, currently isolated solutions are often created that do not unleash the full potential for resource-efficient AI. In this project, we will focus on a holistic approach: from hardware to efficient coding and transfer of data and models to dynamic and resource-adaptive software to enable multi-criteria optimization of all facets of an AI-enabled system. As an example, we demonstrate the potential of this approach using the scenario of a modern driver assistance system (FAS). With about 67 million registered vehicles and increased e-mobility, saving required energy by combining efficient algorithms, communication, and hardware is urgently needed. Our "Green Assisted Driving" project addresses different energy consumption, safety, and flexibility metrics. The consortium combines low-power hardware, learning of efficient representations from large data sets, hyperparameter optimization, and network design using AutoML, as well as methods of transfer learning, semi-supervised learning, and network pruning to prototype highly efficient and dynamically controllable models on a FAS. and demonstrate the savings potential of a holistic approach.

  • Efficient Real-time Processing of EEG-Signals
    A brain-computer interface (BCI) is a system that generates signals to control an artificial system based on measurements of the activity of the central nervous system, for example, to replace, enhance or supplement certain tasks of human action. Modern BCIs are often based on the decoding or interpretation of EEG signals, as such systems are both non-invasive and cost-effectively available. These sensors detect a variety of independent, superimposed signals that make their immediate use for controlling a digital system difficult. Therefore, each application and corresponding application environment requires specifically designed and customized algorithms. This project therefore investigates methods for the efficient real-time processing of EEG signals. For this purpose, the Institute of Microelectronic Systems is developing a complete system of dedicated, configurable hardware in combination with a signal-processing framework specially adapted for the processing of EEG signals.

  • Design of a Configurable, Massive-Parallel Vector Processor Architecture for Computer Vision and a Framework for the Implementation of Object Recognition Applications for Embedded Systems
    The increasing complexity of current computer vision algorithms for autonomous driving, such as object detection and classification using neural networks, represents a challenge for automotive system designers. Providing a real-time processing system under hard real-time constraints and a low energy (budget a few watts) is difficult to achieve even with current technical platforms. The goal of this project is to design a new approach of application-specific vector processor for FPGA implementation. The well-known overhead of other platforms (e.g. GPUs) shall be avoided by using several strategies: Novel functional mechanisms, a modular and customizable architecture and a suitable development framework, which is especially designed for the implementation of automotive applications.). An FPGA-based prototype will demonstrate the performance of the vector processor concept for a selected application at the end of the project.
