定時中斷程序,源碼的注釋十分詳細,具體功能如下: 1.Frame 實現能有效降低VxWorks 內存管理內部/外部碎片的機制。 2. Frame 實現為系統提供軟定時器功能的機制,定時器timeout 信息以message 或其他快捷有效方式通知定時器申請者(Task)。 3. 參考實驗一要求,系統中每個Task 擁有自己的Message Queue,以此方式作為系統的消息驅動基礎。 4. 系統中各Task 應使用同一類型框架,即統一的Task 框架。 5. 系統內實體(Task/ISR)間傳遞的消息應有統一格式(消息頭+消息體),可分短消息和長消息,但消息頭須至少包含消息ID。系統內所有消息均有其唯一ID 標識。

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.

在了解實時嵌入式操作系統內存管理機制的特點以及實時處理對內存管理需求的基礎上,練習并掌握有效處理內存碎片的內存管理機制,同時理解防止內存泄漏問題的良好設計方法。使用預先規劃的思想,構建自己的私有內存管理機制,在系統內存池中申請內存,并將其納入私有內存管理機制中,形成靜態預分配內存池; 靜態預分配內存池支持一種以上固定長度內存池,如16 字節內存池和256 字節內存池。固定長度內存池的單塊長度應考慮體系結構開銷,并盡量減少內部碎片;固定長度內存池數量應可配置; 靜態預分配內存池與系統內存池的統一管理機制。向用戶分配內存時應保證長度最佳匹配原則。當申請內存的長度超過靜態預分配長度或資源不足時,自動向系統內存池申請; 管理機制包括: a) 初 始化函數; b) 內 存申請/釋放函數。并特別要保證釋放安全; c) 告 警機制; d) 管 理監視機制。 5. 利用可能的互斥機制或代碼可重入設計,保證以上管理機制的操作安全性; 6. 創建多Task 環境測試及演示以上內容

北京大學ACM比賽題目 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.
