    First of all we would like to thank God Almighty for giving us the strength and confidence in pursing the ambitions. We would like to thank our Examiner Professor Axel Jantsch for allowing us to do this under his guidance and encouragement. At the same time we would like to mention our sincere thanks to Mr. Said Zainali, Manager of FRAME ACCESS AB for giving all the required equipment and the technical support which helped us to finish this thesis. We would like to mention our gratitude to our fellow VACS team members who helped us a lot during difficult times.

  • 在采用多道程序设计的系统中

    在采用多道程序设计的系统中,往往有若干个进程同时处于就绪状态。当就绪进程个数大于处理机数时,就必须依照某种策略来决定哪些进程优先占用处理机。本实验模拟在单处理机情况下的处理机调度,帮助学生加深了解处理机调度的工作。 二、实验类型 设计型。 三、预习内容 预习课本处理机调度有关内容,包括进程占用处理机的策略方法。 四、实验要求与提示 设计进程调度算法,进程数不定;包含几种调度算法,并加以实现;输出进程的调度过程——进程的状态、链表等。要求使用优先权法和轮转法模拟进程调度过程。 【提示】:简化假设 1) 进程为计算型的(无I/O) 2) 进程状态:ready、running、finish 3) 进程需要的CPU时间以时间片为单位确定 【提示】:算法描述 1) 优先权法——动态优先权,当前运行进程用完时间片后,其优先权减去一个常数。 2) 轮转法

  • The running time of quicksort can be improved in practice by taking advantage of the fast running t

    The running time of quicksort can be improved in practice by taking advantage of the fast running time of insertion sort when its input is “nearly” sorted. When quicksort is called on a subarray with fewer than k elements, let it simply return without sorting the subarray. After the top-level call to quicksort returns, run insertion sort on the entire array to finish the sorting process.
