In network on chips (NoCs) design, reconfiguration of NoC is a very effective option for minimizing power consumption, and Gaussian networks can provide significant advantage over the mesh networks in terms of network diameter, average hop distance and so on. In this paper, based on the special topology structure and the static connection rules within Gaussian networks, we present the reconfiguration...
The complicated calculations and data dependency have limited further application of the H.264/ AVC standard for a considerable time. To solve such a problem, here in this paper, a dual-parallel architecture that combines block parallel processing and mode parallel processing is proposed to speed up the process. Since the improvement of the parallelism will lead to increased consumption of the hardware...
Traditional barcode recognition algorithm usually do not fit the cylindrical code but the one on flat surface. This paper proposes a low-cost approach to implement recognition of the curved QR codes printed on bottles or cans. Finder patterns are extracted from detecting module width proportion and corners of contours and an efficient direct least-square ellipse fitting method is employed to extract...
In this paper, an innovative method to analyze the software specifications by using a model based on the Markov Chain is proposed. It is well known that all kinds of software are executed via the instruction set of the processor. Since the instruction set can be classified and divided into a series of finite state (i.e. the finite-state machine), it is natural that the software programs based on it...
This paper presents a dynamic range enhanced visual sensor circuit and its application for multi-object detection based on LGMD (Lobula Giant Movement Detection) method. The proposed visual sensor incorporates a DR (Dynamic Range) extension circuit with the general pipeline AD Converter. Therefore little changes are needed to achieve the DR extension. Together with the modified LGMD model, our system...
In this paper, a new method for analog design reuse during technology migration is proposed. Previous works ignore the variance of technology parameters. Accordingly, bases on gm/id methodology and ACM model, our methodology adopts an extra pre-extraction step for parameters deciding. This enables a practical description of MOS transistor working state and is therefore more precisely in deciding the...
With the increasing of wind penetration in power systems, many national grid codes demand complete models and simulation studies under different system conditions in order to ensure that the connection of a wind farm would not have a detrimental impact on the grid. It is now recognized that doubly fed induction generators (DFIG) are used in many large farms. A systematic control methodology for connection...
