We present a parallel algorithm, architecture, and implementation for eecient Lempel-Ziv-based data compression. The parallel algorithm exhibits a scalable, pa-rameterized, and regular structure and is well suited for VLSI array implementation. Based on our parallel algorithm and systematic design methodologies 12], two semi-systolic array architectures have been developed which are low power a...

This paper addresses power allocation methods for multimedia signals over wireless channels. The objective is to minimize total power allocated for image compression and transmission, while the power for each bit is kept at a predetermined value. Minimum and maximum power adaptation methods are proposed. In this work, an approach for minimizing the total power allocated of a multimedia like ima...

As lasers become progressively higher in power, optical damage thresholds will become a limiting factor. Using the nonlinear optics of plasma may be a way to circumvent these limits. Here, we present a new self-compression mechanism for high-power, femtosecond laser pulses based on geometrical focusing and three dimensional spatiotemporal reshaping in an ionizing plasma. By propagating tightly ...

We present nonlinear pulse compression of a high-power SESAM-modelocked thin-disk laser (TDL) using an Ar-filled hypocycloid-core kagome hollow-core photonic crystal fiber (HC-PCF). The output of the modelocked Yb:YAG TDL with 127 W average power, a pulse repetition rate of 7 MHz, and a pulse duration of 740 fs was spectrally broadened 16-fold while propagating in a kagome HC-PCF containing 13 ...

The importance of low-power design is not just critical to portable devices but also to line powered equipment like TV products. Power dissipation strongly influences the price of the chip, since the packaging and cooling costs increase dramatically with increasing power dissipation. In this paper, we analyse architectures that enable the design of a low-power picture-rate up-conversion module,...

One of the parameters of the pulsed RADAR that contributes range capability is the average power of the transmitter. The average power can be increased by increasing the peak power or transmitted pulse width or both. The complexity in the design of transmitter components to withstand high peak power is the most challenging task. On the other hand larger transmitted pulse width affects the RADAR...

The overall power consumption of CMOS imagers is dominated by the communication layer. A number of compression techniques have been introduced in the processing layer to reduce the power consumption of the communication layer. These compression techniques use redundancy present in the spatial or temporal domain. This work presents an algorithm to compress the depth of the pixel in the digital d...

H.264/AVC video compression standard provides high coding efficiency, but it has high complexity and consumes more power. This paper explains advantages of H.264 audio video codec and why this H.264 technology should be on the shopping list of every business. Digital video streams, especially at high definition (HD) resolution, represent huge amounts of data. In order to achieve real-time HD re...
