    查看更多>>摘要：MV10 is an MCU which consists of PWM,ADC,CAN and some other function blocks.It is designed for car body's control.Advanced peripheral bus (APB) is a low speed AMBA bus connecting low-power peripherals.This paper presents an implementation of APB interface for MV10 MCU.After that,MV10 can be integrated into any AMBA system on chips (SoCs) easily.We have built a multi-core system with ABMA to verify this design.In this system ARM9 is a main processor mounted on AHB and MV10 acts as a low-power and low-speed slaver on APB.Before building this system,some operations are encapsulated into a task with dedicated ID.MV10 works as a co-processor with ARM by acquiring task ID from ARM.The result of simulation indicates that MCU can work well as expected.Based on our design,MV10 can be mounted on any AMBA system from now on.

    Optimal strategy of searching FPD weights scanning matrix using GA-PSO

    YAN Li-minGU Yu-canLI Jian-dong
    292-296页
    查看更多>>摘要：This paper discusses a kind of optimal method used for searching flat panel display (FPD) scanning matrix.The method adopts bionic algorithm:genetic algorithm (GA) and particle swarm optimization (PSO) algorithm.The method using single GA is more time-consuming,and the search efficiency is low in later evolution; the PSO algorithm is easily falling into the local optimal solution and appears the premature convergent phenomenon.Hence,a hybrid approach of GAPSO is found to optimize the search for high grayscale weights scanning matrix.Finally in the acceptable time,it finds a weight scanning matrix (WSM) of 256 gray scales with Matlab,whose scanning efficiency reaches 94.73％ and the linearity is very good.

The development platform has been used not only in testing and verification of the FPD devices,but also in building OLED-powered handheld digital devices,shortening the development cycle from OLED devices to mature application products.

    Adaptive early termination of fast mode decision in MVC based on inter-view correlation

    SHEN Li-quanZHANG Zhao-yangYANG Gao-bo
    321-324页
    查看更多>>摘要：Variable size motion estimation (ME) and disparity estimation (DE) are employed to select the best coding mode for each macroblock (MB) in the current joint multiview video model (JMVM).This technique achieves the highest possible coding efficiency,but it results in extremely large computation complexity which obstructs the multiview video coding (M C)from practical application.This paper proposes an adaptive early termination of fast mode decision algorithm for MVC.It makes use of the coding information of the corresponding MBs in neighbor view based on inter-view correlation to early terminate the mode decision procedure.Experimental results show that the proposed fast mode decision algorithm can achieve computational 50％ computation saving with no significant loss of rate distortion (RD) performance.

    331-334页
    查看更多>>摘要：Mobile devices are increasingly powerful in multimedia transmitting and browsing. However,the small screen and different aspect ratios of mobile devices lower visual quality while watching images or videos.Video retargeting is aim at fitting an existing video into arbitrary size and aspect ratio.Previous content-aware retargeting methods are mostly high computational cost,which limits their applications on the portable devices with low computation ability.In this paper,a new crop-and-scale approach is presented to adapt video to better suit the target display.We automatically find the optimal parameters of cropping window using the dynamic programming method,and then scale it to fit the target display.The cropping window can smoothly shift during a shot to follow the movementof important objects.The retargeting results using our approach introduce no deformation and jitter effects over the whole video.Experimental results show the success of our approach on adapting a variety of source videos to small display sizes.
