    Summary form only given. Multimedia systems are typically computation intensive. Ever more complex algorithms and the continuous increasing resolution suggest that this trend will continue for the foreseeable future. Silicon IC technology scaling delivers the required transistor densities to meet the computational needs of multimedia systems, however, at an ever increasing cost. Changes in the tec...

    We present a high-performance and low-power pure-hardware accelerator for decoding H.264/AVC video. We propose novel VLSI architectures for every stage of the decoding pipeline. We wrap the decoder core with an AMBA bus interface, integrate it into a multimedia SOC platform, and verify it with FPGA prototyping. In order to reduce external memory traffic, we propose a memory fetch unit to increase ... View full abstract»

    JPEG XR is an emerging image coding standard, based on HD Photo developed by Microsoft. It supports high compression performance twice as high as the de facto image coding system, namely JPEG, and also has an advantage over JPEG 2000 in terms of computational cost. JPEG XR is expected to be widespread for many devices including embedded systems in the near future. In this paper, we propose a novel... View full abstract»

    In this paper, we present a high-throughput, area-efficient, hardware accelerator for the deblocking filter in H.264/AVC video compression standard. In order to achieve this goal, we start with algorithmic optimization and propose a novel decomposition of the filter kernels for the deblocking filter. The proposed decomposition reduces the number of adders by 51% and thereby greatly reduces the are... View full abstract»

    For all video applications, large amounts of data are processed within a bounded time. These data are usually stored in a low-cost slow external DRAM which results in high memory bandwidth requirement. The memory bandwidth will dominate the system performance, especially for applications running on embedded systems. In this paper, we propose an effective dictionary-based compression and de-compres... View full abstract»

    As single-processor systems are ceasing to scale effectively, multi-processor systems are becoming more and more popular. While there are many challenges of designing multi-processor systems in hardware, writing efficient parallel applications that utilize the computing capability of multiple processors may reveal to be even more challenging. In this paper, we introduce a framework that allows to ... View full abstract»

    The increasing demand for low power and high performance multimedia embedded systems has motivated the need for effective solutions to satisfy application bandwidth and latency requirements under a tight power budget. As technology scales, it is imperative that applications are optimized to take full advantage of the underlying resources and meet both power and performance requirements. We propose...

    An exciting class of storage devices is emerging: the class of Micro-Electro-Mechanical storage Systems (MEMS). Properties of MEMS-based storage devices include high density, small form factor, and low power. The use of this type of devices in mobile infotainment systems, such as video cameras is not at all obvious. We must explore their configuration and assess their benefit with respect to exist...

    We have integrated processing with deterministic and non-deterministic resource usage in an overall application and evaluated its performance on a multi-core processor platform. The non-determinism involves image analysis, which features a high variation in computing and memory requirements, as opposed to regular stream-oriented video processing. Quality-of-Service (QoS) control is based on resour... View full abstract»

    Multimedia applications are often characterised by implicit temporal constraints but, in many cases, they are not programmed using any specialised real-time API. These ¿¿Legacy applications¿¿ have no way to communicate their temporal constraints to the OS kernel, and their quality of service (QoS), being necessarily linked to the temporal behaviour, fails to satisfy acceptable standards.

    The complexity of today's embedded systems forces designers to model and simulate systems and their components to explore the wide range of design choices. Such design space exploration is especially needed during the early design stages, where the design space is at its largest. Due to the exponential design space in real problems, evaluating and comparing every single point in the design space i... View full abstract»

    In this paper, we propose a new methodology for optimal memory mapping of data and instructions to Scratch-Pad Memories (SPM). In the mapping process, we optimize, as the main priority, the number of memory accesses to minimize power consumption. Minimization of external memory accesses lowers switching activity and therefore power consumption. The optimization is done by finding Pareto-points, us... View full abstract»

    Synchronous dataflow graphs (SDFGs) are widely used to model streaming applications such as signal processing and multimedia applications. These are often implemented on resource-constrained embedded platforms ranging from PDAs and cell phones to automobile equipment and printing systems. Trade-off analysis between resource usage and performance is critical in the life cycle of those products, fro... View full abstract»
