A novel two-dimension (2-D) parity checking architecture is proposed for radiation-hardened by design (RHBD) SRAMs, which are insensitive to radiation-induced single-event upsets (SEU). The common 2-D parity checking method and its limitations in high density RHBD SRAMs are discussed. The novel architecture, which could be used to correct up to four adjacent upset errors, is more suitable for protecting...
Face detection is the cornerstone of a wide range of applications such as video surveillance, robotic vision and biometric authentication. One of the biggest challenges in face detection based applications is the speed at which faces can be accurately detected. In this paper, we present a novel SoC (System on Chip) architecture for ultra fast face detection in video or other image rich content. Our...
Resonant clock is a new design technique for clock distribution that is gaining prominence in the design of low power and high frequency digital designs. To evaluating the performance of resonant clocks, a statistical clock skew modeling for resonant clock distribution network is presented in this paper, supporting the design of low power, skew, and jitter resonant H-tree clock distribution networks...
Achieving high link speed and reliability is a key challenge in network-on-chip (NoC) design. To address the challenge,, we propose the equalization scheme and the joint equalization technique and special spacing rules solution for improving the communication speed and reliability for NoC links in the paper. The proposed equalizer employs a variable threshold inverter whose switching threshold is...
To reduce the area and developing time of the Memory Built-in Self-Test (MBIST) circuit has been challenged in the market. An architecture that could test memories different in size by only one MBIST circuit is presented in this paper. It is achieved by adding a data processing module and an address processing module into the mature and ready-made MBIST architecture. Base on this architecture, a MBIST...
ZnO is a wide band gap semiconductor material and has a large electromechanical coupling coefficient. ZnO has great potential for photoelectronic devices, acousto-optic devices and SAW devices. In this paper, ZnO films were deposited on quartz substrates by RF magnetron sputtering, with depositing and annealing parameters optimized through the orthogonality method. High-purity (99.999%) ZnO target,...
In this paper, we propose an optimized coding system for progressive image transmission. This system includes a robust image compression algorithm based on the improved set partitioning in hierarchical trees (I-SPIHT) coder. The main idea of ISPIHT is to divide wavelet coefficients into two parts and differential pulse code modulation (DPCM) was applied on the important part while set partitioning...
As traditional Chinese calligraphic (TCC) occupies an important place in the life of modern Chinese, there are a lot of TCC images digitalized and exhibited on the Internet. However, effective classification in them is an imperative problem need to be addressed. The paper proposes a content-based classification scheme that represents the visual content of TCC images by a textural feature set. Four...
Base on the theory of location quotient (LQ)and the characteristics of regional logistics, four quotients are constructed. This paper describes the regional distribution of China logistic agglomeration and its formation mechanism by the clustering analysis of statistical data of China Logistic Industry from 1999 to 2004. We conclude that spatial distribution in regional logistics agglomeration shows...
A novel robust digital image watermarking algorithm based on predictive vector quantization is proposed in this paper. The robust watermark is embedded in the image by selecting the prediction mode of each PVQ coded vector according to the watermark bit. The proposed watermarking algorithm is proved to be robust against both friendly and hostile attacks, such as JPEG compression, VQ compression and...
