  • 定时中断程序

    定时中断程序,源码的注释十分详细,具体功能如下: 1.Frame 实现能有效降低VxWorks 内存管理内部/外部碎片的机制。 2. Frame 实现为系统提供软定时器功能的机制,定时器timeout 信息以message 或其他快捷有效方式通知定时器申请者(Task)。 3. 参考实验一要求,系统中每个Task 拥有自己的Message Queue,以此方式作为系统的消息驱动基础。 4. 系统中各Task 应使用同一类型框架,即统一的Task 框架。 5. 系统内实体(Task/ISR)间传递的消息应有统一格式(消息头+消息体),可分短消息和长消息,但消息头须至少包含消息ID。系统内所有消息均有其唯一ID 标识。

    The IA-32 Software Developer’s Manual, Volume 3: System Programming Guide (Order Number 245472), is part of a three-volume set that describes the architecture and programming environment of all IA-32 Intel® Architecture processors. The IA-32 Software Developer’s Manual, Volume 3, describes the operating-system support environment of an IA-32 processor, including memory management, protection, task management, interrupt and exception handling, and system management mode. It also provides IA-32 processor compatibility information. This volume is aimed at operating- system and BIOS designers and programmers.

  • 在了解实时嵌入式操作系统内存管理机制的特点以及实时处理对内存管理需求的基础上

    在了解实时嵌入式操作系统内存管理机制的特点以及实时处理对内存管理需求的基础上,练习并掌握有效处理内存碎片的内存管理机制,同时理解防止内存泄漏问题的良好设计方法。使用预先规划的思想,构建自己的私有内存管理机制,在系统内存池中申请内存,并将其纳入私有内存管理机制中,形成静态预分配内存池; 静态预分配内存池支持一种以上固定长度内存池,如16 字节内存池和256 字节内存池。固定长度内存池的单块长度应考虑体系结构开销,并尽量减少内部碎片;固定长度内存池数量应可配置; 静态预分配内存池与系统内存池的统一管理机制。向用户分配内存时应保证长度最佳匹配原则。当申请内存的长度超过静态预分配长度或资源不足时,自动向系统内存池申请; 管理机制包括: a) 初 始化函数; b) 内 存申请/释放函数。并特别要保证释放安全; c) 告 警机制; d) 管 理监视机制。 5. 利用可能的互斥机制或代码可重入设计,保证以上管理机制的操作安全性; 6. 创建多Task 环境测试及演示以上内容

    北京大学ACM比赛题目 In 1742, Christian Goldbach, a German amateur mathematician, sent a letter to Leonhard Euler in which he made the following conjecture: Every even number greater than 4 can be written as the sum of two odd prime numbers. For example: 8 = 3 + 5. Both 3 and 5 are odd prime numbers. 20 = 3 + 17 = 7 + 13. 42 = 5 + 37 = 11 + 31 = 13 + 29 = 19 + 23. Today it is still unproven whether the conjecture is right. (Oh wait, I have the proof of course, but it is too long to write it on the margin of this page.) Anyway, your task is now to verify Goldbach s conjecture for all even numbers less than a million.
