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. 相似文献

为了全面了解哈尔滨体育学院学生近10年的体质健康变化情况,采用实验法对哈尔滨体育学院2003至2012级学生进行身高、体重、肺活量、握力(男)、坐位体前屈(女)、立定跳远、台阶实验测试,并将测试数据进行整理,对比10年变化情况。结果表明,近10年,学生身高、体重和体质指数变化不大,其中男生平均体质批量数较高,女生正常;台阶指数、立定跳远和坐位体前屈总体上呈下降趋势,其中立定跳远和台阶指数总本上处于良好水平,坐位体前屈虽呈下降趋势,但各年级均处于优秀水平;肺活量和握力出现波动,且处于及格水平,但哈尔滨体育学院学生体质健康状况好于其他普通高校,与同类体育院校相当;所有年级中2004级、2(107级和2012级学生体质健康状况好于其他年级,2009级、2010级和2011级则较差。哈尔滨体育学院学生体质健康状况整体上呈下降趋势,各年级学生呼吸机能一般,心肺功能和下肢爆发力较好;男生超重,上肢手臂力量偏低;女生身体形态发育正常,柔韧素质好。 相似文献

In developing countries, taxation is perceived as a brake on economic growth. Indeed, taxes in most of these countries are not sufficiently adapted to the specificity of the taxpayer and often do not consider the weak administrative capacity of the countries in the region. In this context, reforms have been initiated over the last decade to create tax environments that encourage savings, investment, entrepreneurship, and social innovation. This study provides an overview of research on the effects of taxation on social innovation and the corresponding implications for the achievement of Sustainable Development Goals (SDGs) in developing countries, taking three approaches: thematic, chronological, and methodological. Most studies agree that high taxes in business undermine social innovation and thus the achievement of SDGs, as social innovation is known to be a driver of most SDGs and business the vehicle. The majority of the selected studies used primary data collected from samples whose representativeness with respect to the population concerned (notably businesses) is still not explicitly justified. 相似文献

The present study replicates and extends an experiment by Bruner and Kenney (Bruner, J. S. American Psychologist, 1964, 19, 1–15; Beyond the information given, NY: Allen & Unwin, 1973;Bruner, J. S., Olver, R. R., & Greenfield, P. M. et al. (Eds.), Studies in cognitive growth, NY: Wiley, 1966). Children aged 5 to 11 were shown pairs of glasses containing water and were asked if one glass of each pair was fuller or emptier and to give the reason. Children aged 12 to 15 and adult subjects were subsequently included but asked to judge only fullness.The glasses differed in height, diameter, and water level and consequently in volume of water and volume of unfilled space, and in proportion full and proportion empty.It is shown that the Bruner experiment reveals weaknesses in design and procedure and focuses on the dichotomous sense of fullness rather than the partial dimension explored in the present study. Contrary to earlier findings the present results indicate that the child tends to think of fullness and emptiness in the same manner and that, far from the concept being mastered at age 11, it is still not completely understood in adulthood.By 11 years the child can cope with fractions and compare volumes, but at age 15 and in adulthood he is still not fully aware that he must not only estimate the volume of the container that is filled but also relate this volume to the total volume of the container and finally compare the two ratio measures obtained.The results are discussed in terms of Bruner's representation-conflict hypothesis, Clark's (Journal of Verbal Learning and Verbal Behvaior, 1971, 10, 266–275; Semantic development in language acquisition.

分别用火焰原子吸收法和1,10-菲啰啉分光光度法测定铬铁废液中铁的总量.绘制了两种方法的标准曲线,测定了空白值、加标回收率和标准样品.两种方法的空白值都比较稳定,相关性以及斜率等数值都很接近,它们的准确度都比较好,相对标准偏差分别为1.2%和2.6%.两者的平均回收率分别为108%和94%,基本符合实验要求.因此,两种方法的测定结果都在真值允许范围内,它们的标准曲线,精密度和准确性都比较好.两种方法的结果通过t检验,无显著性差异.两者都适用于低浓度的铁溶液,但分光光度法灵敏度稍高. 相似文献
