    In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn t kept waiting any longer than necessary for the relatively slow disks.

  • Problem D:合唱队形 Time Limit:1000MS Memory Limit:65536K Total Submit:1237 Accepted:437 Language

    Problem D:合唱队形 Time Limit:1000MS Memory Limit:65536K Total Submit:1237 Accepted:437 Language: not limited Description N位同学站成一排,音乐老师要请其中的(N-K)位同学出列,使得剩下的K位同学排成合唱队形。 合唱队形是指这样的一种队形:设K位同学从左到右依次编号为1,2…,K,他们的身高分别为T1,T2,…,TK, 则他们的身高满足T1 < T2 < ...< Ti > Ti+1 > … >TK(1<=i<=K)。 你的任务是,已知所有N位同学的身高,计算最少需要几位同学出列,可以使得剩下的同学排成合唱队形。 Input 输入包含若干个测试用例。 对于每个测试用例,输入第一行是一个整数N(2<=N<=100),表示同学的总数。第二行有N个整数,用空格分隔,第i个整数Ti(130<=Ti<=230)是第i位同学的身高(厘米)。当输入同学总数N为0时表示输入结束。 Output 对于每个测试案例,输出包括一行,这一行只包含一个整数,就是最少需要几位同学出列。 Sample Input 8 186 186 150 200 160 130 197 220 3 150 130 140 0 Sample Output 4 1

  • 单片机P0口的片外数据存储器扩展

    单片机作为一种微型计算机,其内部具有一定的存储单元(8031除外),但由于其内部存储单元及端口有限,很多情况下难以满足实际需求。为此介绍一种新的扩展方法,将数据线与地址线合并使用,通过软件控制的方法实现数据线与地址线功能的分时转换,数据线不仅用于传送数据信号,还可作为地址线、控制线,用于传送地址信号和控制信号,从而实现单片机与存储器件的有效连接。以单片机片外256KB数据存储空间的扩展为例,通过该扩展方法,仅用10个I/O端口便可实现,与传统的扩展方法相比,可节约8个I/O端口。 Abstract:  As a micro-computer,the SCM internal memory has a certain units(except8031),but because of its internal storage units and the ports are limited,in many cases it can not meet the actual demand.So we introduced a new extension method,the data line and address lines combined through software-controlled approach to realize the time-conversion functions of data lines and address lines,so the data lines not only transmited data signals,but also served as address lines and control lines to transmit address signals and control signals,in order to achieve an effective connection of microcontroller and memory chips.Take microcontroller chip with256KB of data storage space expansion as example,through this extension method,with only10I/O ports it was achieved,compared with the traditional extension methods,this method saves8I/O ports.
