H.264 and MPEG-4 Video Compression: Video Coding for Next-generation Multimedia

We survey recent developments in the design of large-capacity content-addressable memory (CAM). A CAM is a memory that implements the lookup-table function in a single clock cycle using dedicated comparison circuitry. CAMs are especially popular in network routers for packet forwarding and packet classification, but they are also beneficial in a variety of other applications that require high-speed table lookup. The main CAM-design challenge is to reduce power consumption associated with the large amount of parallel active circuitry, without sacrificing speed or memory density. In this paper, we review CAM-design techniques at the circuit level and at the architectural level. At the circuit level, we review low-power matchline sensing techniques and searchline driving approaches. At the architectural level we review three methods for reducing power consumption.

Content-addressable memory (CAM) circuits and architectures: a tutorial and survey

Advances in wireless communication technologies, such as wearable and implantable biosensors, along with recent developments in the embedded computing area are enabling the design, development, and implementation of body area networks. This class of networks is paving the way for the deployment of innovative healthcare monitoring applications. In the past few years, much of the research in the area of body area networks has focused on issues related to wireless sensor designs, sensor miniaturization, low-power sensor circuitry, signal processing, and communications protocols. In this paper, we present an overview of body area networks, and a discussion of BAN communications types and their related issues. We provide a detailed investigation of sensor devices, physical layer, data link layer, and radio technology aspects of BAN research. We also present a taxonomy of BAN projects that have been introduced/proposed to date. Finally, we highlight some of the design challenges and open issues that still need to be addressed to make BANs truly ubiquitous for a wide range of applications.

Body Area Networks: A Survey

In this paper, the proposed pipelined FFT processor, which is based on MRMDF structure, can deal with the simultaneous multiple input sequences more efficiently for MIMO OFDM applications. Furthermore, the hardware costs of memory and complex multipliers in our method can be saved by means of delay feedback and data scheduling approaches. The higher-radix FFT algorithm is also realized in our processor to reduce the number of complex multiplications. A test chip for 802.11n system has been designed using 0.13mum 1P8M CMOS process with core area of 2142 times 660 mum2. Power dissipation is 5.2mW when 128 points FFT with four data streams are calculated

Smart sensors are currently demanded in various kinds of applications to pave a way for better life. To reach this goal, it is necessary to provide energy-efficient solutions with analysis capability. Though state-of-the-art SoC's can meet μW-level processing requirements, front-end sensors remain a bottleneck to be solved. In this paper, a few sensors based on event-driven techniques to improve energy-efficiency and accuracy will be first addressed. Then an ECG-SoC for mobile health-care applications will be described and illustrated.

A dynamic phase and frequency recovery (DPR & DFR) is proposed for power reduction and performance improvement. By the DPR, signal sampling rate is reduced from Nyquist rate (or higher) to the symbol rate, resulting in reduced ADC circuit power. By the DFR, data is recovered from less-interfered signals. In the MB-OFDM UWB system, the simulations show that the system improves 2.3 dB SNR and reduce 43.75% ADC power consumption with the proposed techniques.
