  • Dedicated object processor for mobile augmented reality - sailor
           assistance case study

    • First page: 1
      Abstract: This paper addresses the design of embedded systems for outdoor augmented reality (AR) applications integrated to see-through glasses. The set of tasks includes object positioning, graphic computation, as well as wireless communications, and we consider constraints such as real-time, low power, and low footprint. We introduce an original sailor assistance application, as a typical, useful, and complex outdoor AR application, where context-dependent virtual objects must be placed in the user field of view according to head motions and ambient information. Our study demonstrates that it is worth working on power optimization, since the embedded system based on a standard general-purpose processor (GPP) + graphics processing unit (GPU) consumes more than high-luminosity see-through glasses. This work presents then three main contributions, the first one is the choice and combinations of position and attitude algorithms that fit with the application context. The second one is the architecture of the embedded system, where it is introduced as a fast and simple object processor (OP) optimized for the domain of mobile AR. Finally, the OP implements a new pixel rendering method (incremental pixel shader (IPS)), which is implemented in hardware and takes full advantage of OpenGL ES light model. A GP+OP(s) complete architecture is described and prototyped on field programmable gate-array (FPGA). It includes hardware/software partitioning based on the analysis of application requirements and ergonomics.

  • Symbolic execution and timed automata model checking for timing analysis
           of Java real-time systems

    • First page: 2
      Abstract: This paper presents SymRT, a tool based on a combination of symbolic execution and real-time model checking for timing analysis of Java systems. Symbolic execution is used for the generation of a safe and tight timing model of the analyzed system capturing the feasible execution paths. The model is combined with suitable execution environment models capturing the timing behavior of the target host platform including the Java virtual machine and complex hardware features such as caching. The complete timing model is a network of timed automata which directly facilitates safe estimates of worst and best case execution time to be determined using the Uppaal model checker. Furthermore, the integration of the proposed techniques into the TetaSARTS tool facilitates reasoning about additional timing properties such as the schedulability of periodically and sporadically released Java real-time tasks (under specific scheduling policies), worst case response time, and more.

  • Dual-access way-prediction cache for embedded systems

    • Authors: Yul Chu, Jin Park
      First page: 16
      Abstract: Way-prediction (WP) caches have advantages of reducing power consumption and latency for highly associative data caches and thus are favorable for embedded systems. In this paper, we propose an enhanced way-prediction cache, dual-access way-prediction (DAWP) cache, to cope with the weakness of the WP cache. The prediction logic designed for the DAWP cache contains a scaled index table, a global history register, and a fully associative cache to achieve higher prediction accuracy, which eventually yields less energy consumption and latency. In our practice, performance measurement is done with a simulation model, which is implemented with SimpleScalar and CACTI, and nine SPEC2000 benchmark programs. Our experimental results show that the proposed DAWP cache is highly efficient in power and latency for highly associative cache structures. The efficiency is increased with the increasing associativity, and the testing results with 64 KB cache show that the DAWP cache achieves 16.45% ~ 75.85% power gain and 4.91% ~ 26.96% latency gain for 2-way ~ 32-way structures, respectively. It is also observed that the random replacement policy yields better efficiency in power and latency than the LRU (least recently used) policy with the DAWP cache.

  • A methodology for hand and finger motion analysis using adaptive
           probabilistic models

    • Authors: Chutisant Kerdvibulvech
      First page: 18
      Abstract: A methodology for motion analysis and hand tracking based on adaptive probabilistic models is presented. This is done by integrating a deterministic clustering framework and a particle filter together in real time. The skin color of a human hand is firstly segmented. A Bayesian classifier and an adaptive process are utilized for determining skin color probabilities. The methodology enables us to deal with luminance changes. After that, we determine the probabilities of the fingertips by using semicircle models for fitting curves to fingertips. Following this, the deterministic clustering algorithm is utilized to search for regions of interest, and then the Sequential Monte Carlo is also performed to track the fingertips efficiently. Representative experimental results are also included to ensure workability of the proposed framework. Several issues about using the presented method in embedded systems are discussed. The method presented can be used to further develop the associated applications of embedded robotic and virtual reality.

  • Trade-off between maximum cardinality of collision sets and accuracy of
           RFID reader-to-reader collision detection

    • Authors: Linchao Zhang, Filippo Gandino, Renato Ferrero, Bartolomeo Montrucchio, Maurizio Rebaudengo
      First page: 10
      Abstract: As the adoption of the radio-frequency identification (RFID) technology is increasing, many applications require a dense reader deployment. In such environments, reader-to-reader interference becomes a critical problem, so the proposal of effective anti-collision algorithms and their analysis are particularly important. Existing reader-to-reader anti-collision algorithms are typically analyzed using single interference models that consider only direct collisions. The additive interference models, which consider the sum of interferences, are more accurate but require more computational effort. The goal of this paper is to find the difference in accuracy between single and additive interference models and how many interference components should be considered in additive models. An in-depth analysis evaluates to which extent the number of the additive components in a possible collision affects the accuracy of collision detection. The results of the investigation shows that an analysis limited to direct collisions cannot reach a satisfactory accuracy, but the collisions generated by the addition of the interferences from a large number of readers do not affect significantly the detection of RFID reader-to-reader collisions.

  • Performance analysis of optimal schedulers in single channel dense RFID

    • Authors: Javier Vales-Alonso, Francisco Javier Parrado-Garcia, Juan Alcaraz
      First page: 11
      Abstract: Schedulers in radio frequency identification dense environments aim at distributing optimally a set of t slots between a group of m readers. In single-channel environments, the readers within mutual interference range must transmit at different times; otherwise, interferences prevent identification of the tags. The goal is to maximize the expected number of tags successfully identified within the t slots. This problem may be formulated as a mixed integer non-linear mathematical program, which may effectively exploit available knowledge about the number of competing tags in the reading zone of each reader. In this paper, we present this optimization problem and analyze the impact of tag estimation in the performance achieved by the scheduler. The results demonstrate that optimal solutions outperform a reference scheduler based on dividing the available slots proportionally to the number of tags in each reader. In addition, depending on the scenario load, the results reveal that there exist an optimum number of readers for the topology considered, since the total average number of identifications depend non-linearly on the load. Finally, we study the effect of imperfect tag population knowledge on the performance achieved by the readers.

  • A UHF/UWB hybrid silicon RFID tag with on-chip antennas

    • First page: 12
      Abstract: In this contribution, we describe and analyse a miniature wireless radio frequency identification (RFID) chip with on-chip antennas(OCA)and ultra wideband(UWB)signalling by real-world measurements. With the on-chip antenna approach, no external antennas are required, and the size of the overall tag is identical to the size of the chip alone (3:5mm x 1mm). The chip is powered through inductive coupling and controlled by an RFID signal at 866MHz in the downlink, while the uplink transmits a quaternary pulse-position-modulated (4-PPM) UWB signal at 5:64 GHz with pulses having a duration in the order of nanoseconds. In this contribution, the hybrid or asymmetric communication scheme between prototype chip and reader, the embedded OCA, and the measurement setup are described. The prototype achieves 4-PPM bit rate of 126 Mbit=s based on a pulse-train transmission with a duration of 10 æs. The small size, high data rate, and fine time resolution of the UWB impulse radio offer new features and sensing capabilities for future RFID-like applications.

  • Dynamic voltage and frequency scaling over delay-constrained mobile
           multimedia service using approximated relative complexity estimation

    • Authors: Jihyeok Yun, Deepak Singh, Doug Suh
      First page: 13
      Abstract: This paper deals with dynamic voltage and frequency scaling (DVFS) in mobile multimedia services. The multimedia services that consume a large amount of energy cannot be continuously used in mobile devices because of battery limitation. The DVFS has been applied to multimedia services in previous studies. However, they have only addressed the issue of power saving and overlooked the fact that mobile multimedia services are sensitive to delays. The proposed method is intended to apply DVFS to multimedia services considering potential delays. Another problem with previous studies is that either separate devices have been employed or appropriate frequency scaling values have been determined through complicated calculation processes to apply DVFS to multimedia services. On the contrary, the proposed method determines appropriate frequency scaling values using the characteristics of multimedia contents without employing any separate devices or undergoing complicated calculation processes. This has the advantage of allowing DVFS to be applied to real-time multimedia content. The present paper proposes a DVFS application method that divides multimedia services into video conferences, which are real-time services, and video streaming, which is a non-real-time service, and that reduces energy consumption in a simple manner while considering the constraints of service delays.

  • An embedded multichannel telemetry unit for bone strain monitoring

    • Authors: Fahad Moiz, Sharika Kumar, Walter Leon-Salas, Mark Johnson
      First page: 14
      Abstract: An embedded telemetry unit for bone strain monitoring is presented. The telemetry unit is designed using commercially available components to lower design time and manufacturing costs. The unit can read up to eight strain gauges and measures 2.4 cm × 1.3 cm × 0.7 cm. The unit is powered from a small Li-polymer battery that can be recharged wirelessly through tissue, making it suitable for implanted applications. The average current consumption of the telemetry unit is 1.9 mA while transmitting at a rate of 75 kps and at a sampling rate of 20 Hz. The telemetry unit also features a power-down mode to minimize its power consumption when it is not in use. The telemetry unit operates in the 915-MHz ISM radio band. The unit was tested in an ex vivo setting with an ulna bone from a mouse and in a simulated in vivo setting with a phantom tissue. Bone strain data collected ex vivo shows that the telemetry unit can measure strain with an accuracy comparable to a more expensive benchtop data acquisition system.

  • Agile methods for embedded systems development - a literature review and a
           mapping study

    • First page: 15
      Abstract: There is a wide area of applications that use embedded systems, and the number of such systems keeps growing. The required functionality and complexity of embedded systems are also constantly increasing, and development of such products is becoming increasingly harder. This requires new thinking on the product development processes, and one such emerging philosophy is the agile methods. These methods were created by the software engineering community where they are commonly used. Since then, they have been adopted in embedded systems development; however, whether they can improve the embedded systems product development processes remains an open question. This study aims to bring forth what is known about agile methods in embedded systems development and to find out if agile practices are suitable in this domain and what evidence is there to support the findings. We conducted a literature review and a mapping study to answer these questions. The scope of this study is not only limited to embedded software development, but also to embedded hardware and integrated circuits. We have found that agile methods can be used in the embedded domain, but the methods and practices need to be adapted to suit the more constrained field of embedded product development. Furthermore, the field of embedded product development has wide diversity of products with different needs and domain-specific problems so that no single method is applicable, but rather many methods and practices are needed for different situations.
