Towards a Common Software/Hardware Methodology for Future Advanced Driver Assistance Systems

The European research project DESERVE (DEvelopment platform for Safe and Efficient dRiVE, 2012-2015) had the aim of designing and developing a platform tool to cope with the continuously increasing complexity and the simultaneous need to reduce cost for future embedded Advanced Driver Assistance Systems (ADAS). For this purpose, the DESERVE platform profits from cross-domain software reuse, standardization of automotive software component interfaces, and easy but safety-compliant integration of heterogeneous modules. This enables the development of a new generation of ADAS applications, which challengingly combine different functions, sensors, actuators, hardware platforms, and Human Machine Interfaces (HMI). This book presents the different results of the DESERVE project concerning the ADAS development platform, test case functions, and validation and evaluation of different approaches. The reader is invited to substantiate the content of this book with the deliverables published during the DESERVE project. Technical topics discussed in this book include:Modern ADAS development platforms;Design space exploration;Driving modelling;Video-based and Radar-based ADAS functions;HMI for ADAS;Vehicle-hardware-in-the-loop validation system

Accelerating Color Space Conversion Using Extended Subwords and the Matrix Register File

Color space conversion is an important kernel in multimedia codecs such as JPEG and MPEG. When implemented using SIMD instructions, however, the performance improvement is often limited due to two reasons. First, corresponding color space components are stored at non-unit strides and, second, intermediate results can be larger than 8 bits. In this paper we show that extended subwords and the Matrix Register File (MRF) can be employed to mitigate these limitations. These techniques avoid rearrangement instructions and increase the number of subwords that are processed in parallel. Experimental results have been obtained by extending the SimpleScalar toolset. The results show that extended subwords and the MRF yield a speedup of up to 2.45x and 1.78x over MMX for the RGB-to-YCbCr and YCbCr-to-RGB kernels, respectively. Compared to C implementations, speedups of up to 10.09x and 6.74x, respectively, are obtained. Additionally, the results show that the speedup over MMX is higher for low issue rates. This means that extended subwords and the MRF are suitable techniques for embedded multimedia systems where high issue rates and out-of-order execution are too expensive. The results also show that using more registers improves performance substantially

The Palgrave Handbook of Digital Russia Studies

This open access handbook presents a multidisciplinary and multifaceted perspective on how the ‘digital’ is simultaneously changing Russia and the research methods scholars use to study Russia. It provides a critical update on how Russian society, politics, economy, and culture are reconfigured in the context of ubiquitous connectivity and accounts for the political and societal responses to digitalization. In addition, it answers practical and methodological questions in handling Russian data and a wide array of digital methods. The volume makes a timely intervention in our understanding of the changing field of Russian Studies and is an essential guide for scholars, advanced undergraduate and graduate students studying Russia today
