时钟

The SAA instruction on a Blackfin processor is fast because it utilizes four 8-bit ALUs in each clock cycle.

一个 Blackfin 处理器的 SAA 指令执行速度很快，因为它在每个时钟周期中可利用4个8bit ALU 。

BF533, the fixed-point chip of the Blackfin series product by American Analog Devices, Inc., has high speed clock, unique hardware architecture and high collateral instruction set,which makes it possible to implement MPEG-4 ACC encoder on single DSP chip.

美国模拟器件公司的Blackfin 系列定点BF533芯片具有高速的时钟，独特的硬件结构和高度并行化的指令集，使得在单片DSP 上实现MPEG-4 AAC 编码器成为可能。

Synchronous technology is equivalent to the heart of system of a network, it is the clock signal with the every model correct block transfer in this system.

同步技术相当于一个网络系统的心脏，它为该系统中的每个模块传送正确的时钟信号。

As the tick,tick,tick of the biological clock sounded ever louder,aging baby boomers got down to the business of having a baby boomlet of their own.

随着生物时钟的滴答声愈来愈响，年华日渐老去的婴儿潮这一代，开始营造他们自己的生育小高峰。

Then, we propose a design method named DET(double-edge-triggered) shift register to eliminate the bootless power dissipation of the redundant transition of the clock.

接着，从消除时钟信号冗余跳变而致的无效功耗的要求出发，提出双边沿移位寄存器的设计思想。

To erase the bootless power dissipation of the redundant transition of the clock, a design method named DET (double-edge-triggered) flip-flop using CMOS transmission gate is proposed. The directly pre-set terminals are increased in the design to meet the requirement for practical application.

本文从消除时钟信号冗余跳变而致的无效功耗的要求出发，提出一种基于CMOS传输门的双边沿触发器设计，并设置了它的直接预置控制端以使达到实用的要求。

This paper precisely conducts the special topic research in view of some important technologies of the digitized control module.(1) AC motor control circuit of PAN/TILT is designed ,which speed is controlled by AT89C51 MCU. DC motor control circuit of LENS is designed too.(2) The hardware and software of automatic temperature control is designed, which used in camera protect box without A/D IC. A kind of single wire communication IC is used in the circuit. So, the program is given.(3) A method of video switch without picture shock is discussed in this paper, and 16x8 video switch circuit is designed. AT89C51 can carry out time sequence logical control with the sync signals by request..(4) The module of real-time clock is designed, in which, LCM is used, a kind of three-wire communication IC is used too.

In my silver high-heel shoes,I go to take part in a belated dinner,I go through a tall wood in a rush,On the trees there are fantastic tropical fruits and clocks streamed with egg white,The sweet fragrance of those fruits seduces me,I pick off a beautiful dragon fruit,But see many white worms lying in it when cutting it,I scream and throw it on the ground,Those worms creep to me and begin to grow,I creep onto the tree,They also creep towards the tree wiggling their bodies,I remove my cumbrous high-heel shoes and voile skirt creeping towards a high place,like an agile cheetah,But strangely my small bag oppressively cumbers me,It turns out that the bag is full of pumpkins, monkey dolls with large mouths, crystal bottles and silver coins,I give all of these a vicious discard towards the ground from the tree,But those worms open their big mouths and swallow all of them greedily,Becoming more obese and uglier,I desperately creep upwards,Suddenly the moon is not so far from me,I jump on it with ease,Suddenly finding that the moon is a porous spongy body with the fragrance of the oven-fresh French stick bread,It takes me to flow away from that tree full of worms,I want to light a cigarette but ignite the sponge on the moon,So I descend from the height,Falling down to a huge birds' nest,In an instant my whole body is wrapped by a slick and white egg shell,I find myself becoming a new embryo,Crouching in the warm and ropy liquid,The world presents a color of delicate light yellow,In a vacuum-like silence,I hear my contented voice,"What a perfect world"

我穿着银色的高跟鞋，去参加一场迟到的晚餐，我匆忙地穿过一片高大的树林，树上挂满了奇妙的热带水果和流淌着蛋清的时钟，那些水果甜美的芳香诱惑了我，我摘下一颗漂亮的火龙果，切开来却看见里面躺满了白色的蠕虫，我尖叫着将它们丢在地上，那些蠕虫向我爬来并且开始生长，我爬到树上，蠕虫们也扭动身体朝树上爬来，我脱下了牵绊着我的高跟鞋和纱裙，象只敏捷的猎豹朝高处爬去，只是我的小包奇怪而沉重地拖累了我，原来包里装满了南瓜、大嘴猴玩偶、水晶杯子和银币，我将所有这些朝树下狠狠丢去，那些蠕虫却张开大嘴贪婪地将所有这些吞食下去，并因此变得更加肥大和丑陋，我拼命努力地向上爬，突然月亮就在我不远处了，我轻而易举地跳了上去，恍然发现月亮竟是一个带着刚出炉法棍香味的多孔海绵体，它带我慢慢飘离了蠕虫的树林，我想要点燃一支香烟却不小心引燃了月亮上的海棉，于是我从高处坠落啊坠落，落入一个巨大的鸟巢，顷刻间全身被光滑洁白的蛋壳所包住，我发现自己成为了一个暂新的胚胎，蜷缩在温暖粘稠的液体中，世界呈现出微妙的淡黄色，在真空般的静寂中，我听见自己满足的声音："多完美的世界啊！"

Sometimes, the value of the printed on a flat brush wheel pressure too seriously, to gauge side must increase resistance paper La poorly in this case, you should set the oblato brush round of adjusting screw meanders by inverse rotation axis until the brush, and then press stop to pre-senile meanders turn 1 ~ 2 go, so that the brush can turn in the rotation on paper with the same ease even better.

有时，负纸版上的扁毛刷轮压得太轻，给侧规处事补充必定的阻辛而变成纸弛不推不到位，在这种环境下，答不兵扁毛刷轮的调度螺丝按逆时钟标的目的不静弹，直至毛刷轴罢手不静弹，然后按顺时钟标的目的不静弹1～2不停，使毛刷轮在纸背上能不静弹自若不离算调度好了。

Besides, it is also featured a built-in clock an automatic on and off time.

此外，这亦是精选一个内置的时钟自动和关闭的时间。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
