“…However, we do not have any info about the real task execution and system hardware behavior of that model, but such information is available through the DLU. The data acquisition system proposed in [11] differs from our design in many aspects. In [11], the FPGA log system's main target involves the acquisition of data from analog-todigital converter devices, and this constitutes a huge limit with regard to the flexibility of inputs.…”

In this manuscript, we propose a configurable hardware device in order to build a coherent data log unit. We address the need for analyzing mixed-criticality systems, thus guaranteeing the best performances without introducing additional sources of interference. Log data are essential to inspect the behavior of running applications when safety analyses or worst-case execution time measurements are performed. Furthermore, performance and timing investigations are useful for solving scheduling issues to balance resource budgets and investigate misbehavior and failure causes. We additionally present a performance evaluation and log capabilities by means of simulations on a RISC-V use case. The simulations highlight that such a data log unit can trace the execution from a single- to an octa-core microcontroller. Such an analysis allows a silicon developer to obtain the right sizings and timings of devices during the development phase. Finally, we present an analysis of a real RISC-V implementation for a Xilinx UltraScale+ FPGA, which was obtained with Vivado 2018. The results show that our data log unit implementation does not introduce a significant area overhead if compared to the RISC-V core targeted for tests, and that the timing constraints are not violated.

“…This complexity requires hardware increasingly efficient in terms of computational power. Several FPGAs based controllers have been presented in the literature [27]- [29]. In such context is interesting to investigate the possibility to use mixed architecture composed by a microprocessor and a Hardware accelerator [30]- [32], or alternatively, the use of distributed simulation to evaluate the performance of such complex systems [33], [34], [35], [36].…”

The improvement of the Quality of Life (QoL) and the enhancement of the Quality of Services (QoS) represent the main goal of every city evolutionary process. It is possible making cities smarter promoting innovative solutions by use of Information and Communication Technology (ICT) for collecting and analysing large amounts of data generated by several sources, such as sensor networks, wearable devices, and IoT devices spread among the city. The integration of different technologies and different IT systems, needed to build smart city applications and services, remains the most challenge to overcome. In the Smart City context, this paper intends to investigate the Smart Environment pillar, and in particular the aspect related to the implementation of Smart Energy Grid for citizens in the urban context. The innovative characteristic of the proposed solution consists of using the Blockchain technology to join the Grid, exchanging information, and buy/sell energy between the involved nodes (energy providers and private citizens), using the Blockchain granting ledger.

To sustain in the ever-changing environment and to combat the atmospheric effect, development of a highly efficient and an environment friendly air conditioning system which can run in parallel or as an alternative to an existing vapor compression system is the need of the hour and such novel hybrid air conditioning system are under development today. For the parameters attribution mapping of such novel hybrid air conditioning system, todays commercially available data acquisition systems (DAS) need to be customized to the requirements of addition of sensor nodes and their integration with triggering mechanism for actuation of devices for its programmed operation. Therefore, this paper describes the design and development of novel multichannel data acquisition system (NMDAS) for automobile air conditioning application. The details of the hardware design, software design, error analysis and testing of the NMDAS are presented. The proposed NMDAS uses PLC module DVP16SP configured with analog reader DVP 04TC for temperature measurement at 32 nodes and DVP04AD for pressure or humidity measurements at 8 nodes. The triggering circuit for activation of the relay is enabled using NI LabVIEW user interface and PLC data. The output of the NMDAS is integrated with processor by RS 232 port for data storage and processing. The error analysis of temperature, pressure and humidity measurements are done by comparing with reference calibration standards. The average thermal stability of the temperature sensors over the operating range of -5˚C to 150˚C is 0.0015°C. The average accuracy of pressure transmitters for operating range of pressure 0 to 40bar is estimated 98.219%. The minimum error in the output current is 0.375% and maximum error is 7.125% over relative humidity span of 0%RH to 100% RH respectively. The proposed NMDAS is used for testing of the novel hybrid air conditioning system of automobile during development stage and is found expedient.
