This paper presents the power-performance trade off of three different cache compression algorithms. Cache compression improves performance, since the compressed data increases the effective cache capacity by reducing the cache misses. The unused memory cells can be put into sleep mode to save static power. The increased performance and saved power due to cache compression must be more than the delay...
In this paper, a CMOS chip with programmable capability for cyclic redundancy check (CRC) operation is proposed. By the programmable function, the circuit provides function of CRC-4, CRC-5, CRC-8, or CRC-16. The dual encoding functions including Manchester and Miller codes are also obtained from the circuit. In addition, amplitude-shift keying (ASK) and frequency-shift keying (FSK) modulations are...
Asymmetric stereoscopic coding can save bitrate and maintain the overall visual quality of stereoscopic perception, so it is an alternative for wireless environment in which the bandwidth is limited. In asymmetric stereoscopic coding, the right-view images are down-sampled to half resolution before coding, while the direction of sampling influences the rate-distortion performance of the asymmetric...
As an effective global search method, genetic algorithm has obvious advantages. But it usually has problems of premature convergence and local optimum in practical application. According to this, a new algorithm with improved selection, crossover and mutation is proposed. Through the simulation experiments, the improved algorithm shows its faster convergence and better stability. It is valid which...

In this paper, a Johnson-encoded Reconfigurable Synchronous/Bi-Synchronous (RSBS) FIFO is proposed which can adapt its operation to either synchronous or bi-synchronous mode. The proposed FIFO which can be used to interface modules in Voltage/Frequency Islands (VFI) based Networks-on-chip, is capable of alleviating the excessive energy consumption and high performance overhead of the conventional...
In this paper we describe several one-time signatures and show, by the use of the Merkle tree, that we are able to verify several one-time signatures with one public key. One-time signatures have been the subject of increased attention recently because they have fast verification, their security doesn't rely on number theoretic assumptions, and they appear to resist quantum computing attacks.

This paper investigates the feedback stabilization problem for networked control systems (NCSs) with unknown disturbances, where sensors and actuators communicate with a remote controller over a multi-purpose network. A new control scheme, which relies on both information-theoretic and control-theoretic tools, is proposed to stabilize linear discrete-time plants. A sufficient condition for stabilization...
This paper addresses the stabilization problem for linear discrete-time systems via limited capacity noisy channels, by which sensors and controllers are connected. It is derived that there exists a lower bound of data rates above which there exists a coding and control scheme to stabilize linear discrete-time dynamical systems over noisy communication channels. A sufficiency condition for the stabilization...

With high compression ratio performance, fractal image compression technology becomes a hot topic of research of image compression techniques. However, the encoding time of traditional fractal compression technique is too long to achieve real-time image compression, so it cannot be widely used. Based on the theory of fractal image compression; this paper raised an improved algorithm form the aspect...
This paper investigates the stabilization problem for networked control systems (NCSs) with limited data rates over an additive white Gaussian noise (AWGN) channel.
