| UB02.1 | WORKCRAFT: TOOLSET FOR FORMAL SPECIFICATION, SYNTHESIS AND VERIFICATION OF CONCURRENT SYSTEMS Presenter: Danil Sokolov, Newcastle University, GB Abstract A large number of models that are employed in the field of concurrent systems' design, such as Petri nets, gate-level circuits, dataflow structures have an underlying static graph structure. Their semantics, however, is defined using additional entities, e.g. tokens or node/arc states, which collectively form the overall state of the system. We jointly refer to such formalisms as interpreted graph models. This demo will show the use of an open-source cross-platform Workcraft framework for capturing, simulation, synthesis, and verification of such models. The focus of our case study will be on synthesis from technology-independent formal specifications to verifiable circuit implementations. More information ... |
| UB02.2 | WE DARE: WEARABLE ELECTRONICS DIRECTIONAL AUGMENTED REALITY Presenter: Davide Quaglia, University of Verona, IT Authors: Gianluca Benedetti1 and Walter Vendraminetto2 1Wagoo LLC, IT; 2EDALab srl, IT Abstract Current augmented reality (AR) eyewear solutions require large form factors, weight, cost and energy that reduce usability. In fact, connectivity, image processing, localization, and direction evaluation lead to high processing and power requirements. A multi-antenna system, patented by the industrial partner, enables a new generation of smart eye-wear that elegantly requires less hardware, connectivity, and power to provide AR functionalities. They will allow users to directionally locate nearby radio emitting sources that highlight objects of interest (e.g., people or retail items) by using existing standards like Bluetooth Low Energy, Apple's iBeacon and Google's Eddystone. This booth will report the current level of research addressed by the Computer Science Department of University of Verona and the company Wagoo LLC. In the presented demo, different objects emit an "I am here" signal and a prototype of the smart glasses shows the information related to the observed object. More information ... |
| UB02.3 | TTOOL5G: MODEL-BASED DESIGN OF A 5G UPLINK DATA-LINK LAYER RECEIVER FROM UML/SYSML DIAGRAMS Presenter: Andrea Enrici, Nokia Bell Labs France, FR Authors: Julien Lallet1, Imran Latif1, Ludovic Apvrille2, Renaud Pacalet2 and Adrien Canuel2 1Nokia Bell Labs France, FR; 2Télécom ParisTech, FR Abstract Future 5G networks are expected to provide an increase of 10x in data rates. To meet these requirements, the equipment of baseband stations will be designed using mixed architectures, i.e., DSPs, FPGAs. However, efficiently programming these architectures is not trivial due to the drastic increase in complexity of their design space. To overcome this issue, we need to have unified tools capable of rapidly exploring, partitioning and prototyping the mixed architecture designs of 5G systems. At DATE 2017 University Booth, we demonstrate such a unified tool and show our latest achievements in the automatic code generation engine of TTool/DIPLODOCUS, a UML/SysML framework for the hardware/software co-design of data-flow systems, to support mixed architectures. Our demonstration will show the full design and evaluation of a 5G data-link layer receiver for both a DSP-based and an IP-based designs. We will validate the effectiveness of our solution by comparing automated vs manual designs. More information ... |
| UB02.4 | MATISSE: A TARGET-AWARE COMPILER TO TRANSLATE MATLAB INTO C AND OPENCL Presenter: Luís Reis, University of Porto, PT Authors: João Bispo and João Cardoso, University of Porto / INESC-TEC, PT Abstract Many engineering, scientific and finance algorithms are prototyped and validated in array languages, such as MATLAB, before being converted to other languages such as C for use in production. As such, there has been substantial effort to develop compilers to perform this translation automatically. Alternative types of computation devices, such as GPGPUs and FPGAs, are becoming increasingly more popular, so it becomes critical to develop compilers that target these architectures. We have adapted MATISSE, our MATLAB-compatible compiler framework, to generate C and OpenCL code for these platforms. In this demonstration, we will show how our compiler works and what its capabilities are. We will also describe the main challenges of efficient code generation from MATLAB and how to overcome them.

| UB02.5 | A VOLTAGE-SCALABLE FULLY DIGITAL ON-CHIP MEMORY FOR ULTRA-LOW-POWER IOT PROCESSORS Presenter: Jun Shiomi, Kyoto University, JP Authors: Tohru Ishihara and Hidetoshi Onodera, Kyoto University, JP Abstract A voltage-scalable RISC processor integrating standard-cell based memory (SCM) is demonstrated. Unlike conventional processors, the processor has Standard-Cell based Memories (SCMs) as an alternative to conventional SRAM macros, enabling it to operate at a 0.4 V single-supply voltage. The processor is implemented with the fully automated cell-based design, which leads to low design costs. By scaling the supply voltage and applying the back-gate biasing techniques, the power dissipation of the SCMs is less than 20 uW, enabling the SCMs to operate with ambient energy source only. In this demonstration, the SCMs of the processor operates with a lemon battery as the ambient energy source. More information ... |
| UB02.6 | MARGOT: APPLICATION ADAPTATION THROUGH RUNTIME AUTOTUNING Presenter: Gianluca Palermo, Politecnico di Milano, IT Authors: Davide Gadioli, Emanuele Vitali and Cristina Silvano, Politecnico di Milano, IT Abstract Several classes of applications expose parameters that influence their extra-functional properties, such as the quality of the result or the performance. This leads the application designer to tune these parameters to find the configuration that produces the desired outcome. Given that the application requirements and the resources assigned to each application might vary at runtime, finding a one-fit-all configuration is not a trivial task. For this reason, we implemented the mARGOt framework that enhances an application with an adaptation layer in order to continuously tune the parameters according to the evolving situation. More in detail, mARGOt is composed of a monitoring infrastructure, an application-level adaptation engine and an extra-functional configuration framework based on the separation of concerns paradigm between functional and extra-functional aspects. At the booth, we plan to demonstrate the effectiveness of the proposed infrastructure on three real-life applications. More information ... |
| UB02.7 | ACCELERATORS: RECONFIGURABLE SELF-TIMED DATAFLOW ACCELERATOR & FAST NETWORK ANALYSIS IN SILICON Presenter: Alessandro de Gennaro, Newcastle University, GB Authors: Danil Sokolov and Andrey Mokhov, Newcastle University, GB Abstract Many real-life applications require dynamically reconfigurable pipelines to handle incoming data items differently depending on their values or current operating mode. A demo will show the benefits of an asynchronous accelerator for ordinal pattern encoding with reconfigurable pipeline depth. This was designed, simulated and verified using dataflow structure formalism in Workcraft toolset. The self-timed chip, fabricated in TSMC 90nm, shows high resilience to voltage variation and configurable accuracy of the results. Applications with underlying graph models foster the importance of a fast and flexible approach to graph analysis. To support medicine discovery biological systems are modelled by graphs, and drugs can disconnect some of the connections. A demo will show how graphs can be automatically converted into VHDL designs, which are synthesised into a FPGA for the analysis: thousand times faster than in software. Single stand will be used for both case studies. More information ... |
| UB02.8 | TIDES: NON-LINEAR WAVEFORMS FOR QUICK TRACE NAVIGATION Presenter: Jannis Stoppe, University of Bremen, DE Author: Rolf Drechsler, University of Bremen / DFKI, DE Abstract System trace analysis is mostly done using waveform viewers -- tools that relate signals and their assignments at certain times. While generic hardware design is subject to some innovative visualisation ideas and software visualisation has been a research topic for much longer, these classic tools have been part of the design process since the earlier days of hardware design -- and have not changed much over the decades. Instead, the currently available programs have evolved to look practically the same, all following a familiar pattern that has not changed since their initial appearance. We argue that there is still room for innovation beyond the very classic waveform display though. We implemented a proof-of-concept waveform viewer (codenamed Tides) that has several unique features that go beyond the standard set of features for waveform viewers. More information ... |
| UB02.9 | SEFILE: A SECURE FILESYSTEM IN USERSPACE VIA SECUBE™ Presenter: Giuseppe Airofarulla, CINI, IT Authors: Paolo Prinetto1 and Antonio Varriale2 1CINI & Politecnico di Torino, IT; 2Blu5 Labs Ltd., IT Abstract The SEcube™ Open Source platform is a combination of three main cores in a single-chip design. Low-power ARM Cortex-M4 processor, a flexible and fast Field-Programmable-Gate-Array (FPGA), and an EAL5+ certified Security Controller (SmartCard) are embedded in an extremely compact package. This makes it a unique Open Source security environment where each function can be optimized, executed, and verified on its proper hardware device. In this demo, we present a Windows wrapper for a Filesystem in Userspace (FUSE) with an HDD firewall resorting to the hardware built-in capabilities, and the software libraries, of the SEcube™.

| UB02.10 | LABSMILING: A FRAMEWORK, COMPOSED OF A REMOTELY ACCESSIBLE TESTBED AND RELATED SW TOOLS, FOR ANALYSIS AND DESIGN OF LOW DATA-RATE WIRELESS PERSONAL AREA NETWORKS BASED ON IEEE 802.15.4 Presenter: Marco Santic, University of L'Aquila, IT Authors: Luigi Pomante, Walter Tiberti, Carlo Centofanti and Lorenzo Di Giuseppe, DEWS - Università di L'Aquila, IT Abstract Low data-rate wireless personal area networks (LR-WPANs) are even more present in the fields of IoT, wearable devices and health monitoring. The development, deployment and test of such systems, based on IEEE 802.15.4 standard (and its derivations, e.g. 15.4e), require the exploitation of a testbed when the network is not trivial and grows in complexity. This demo shows the framework of LabSmiling: a testbed and related SW tools that connect a meaningful (but still scalable) number of physical devices (sensor nodes) located in a real environment. It offers the following services: program, reset, switch on/off single devices; connect to devices up/down links to inject or receive commands/msgs/packets in/from the network; set devices as low level packet sniffers, allowing to test/debug protocol compliances or extensions. Advanced services are: possibility of design test scenarios for the evaluation of network metrics (throughput, latencies, etc.) and custom application verification. More information ... |
