T-Ker測試synchronization_communication\semaphore部分的tk_cre_sem,tk_del_sem, tk_sig_sem, tk_wai_sem, tk_ref_sem在移植的uT-Engine上運行是否正常。 api的返回值正確與否,在ads上設斷點觀察,同時用Lpc2104上的LED顯示(如果正確,則程序中設定的LED就閃亮)nel中的FLAG小實驗程序

MODE_Switch1Processing multi-interrupt request needs to set the priority of these interrupt requests. The IRQ FLAGs of the 7 interrupt are controlled by the interrupt event occurring. But the IRQ FLAG set doesn t mean the system to execute the interrupt vector. The IRQ FLAGs can be triggered by the events without interrupt enable. Just only any the event occurs and the IRQ will be logic "1".

About: hamsterdb is a database engine written in ANSI C. It supports a B+Tree index structure, uses memory mapped I/O (if available), supports cursors, and can create in-memory databases. Release focus: Major feature enhancements Changes: This release comes with many changes and new features. It can manage multiple databases in one file. A new FLAG (HAM_LOCK_EXCLUSIVE) places an exclusive lock on the file. hamsterdb was ported to Windows CE, and the Solution file for Visual Studio 2005 now supports builds for x64. Several minor bugs were fixed, performance was improved, and small API changes occurred. Pre-built libraries for Windows (32-bit and 64-bit) are available for download. Author: cruppstahl

lcddrv1.c 為驅動源程序 lcddrv1_user.c為應用程序代碼 功能: 在ioctl中區分所寫的數據是命令,還是地址加數據,FLAG=1是只寫命令,FLAG=0時寫地址和數據的組合, 地址號在前面,顯示的字在后面

NAME: u2440mon.c DESC: u2440mon entry point,menu,download HISTORY: Mar.25.2002:purnnamu: S3C2400X profile.c is ported for S3C2410X. Mar.27.2002:purnnamu: DMA is enabled. Apr.01.2002:purnnamu: isDownloadReady FLAG is added. Apr.10.2002:purnnamu: - Selecting menu is available in the waiting loop. So, isDownloadReady FLAG gets not needed - UART ch.1 can be selected for the console. Aug.20.2002:purnnamu: revision number change 0.2 -> R1.1 Sep.03.2002:purnnamu: To remove the power noise in the USB signal, the unused CLKOUT0,1 is disabled.

我所采用的內存管理思想是鏈表管理思想,內存分配方案是最佳適應方案(best fit)。其主要的數據結構為 struct node { char* p int memosize int FLAG struct node* next } 這是一個鏈表的結點的數據結構,用它來管理內存的分配與回收。P 表示所指的分配的內存的首地址,memosize 表示分配的內存塊的大小,FLAG 為一個標志量,表示內存塊是否被占用。用 1 和 0 來表示被占用和不被占用。next 表示下一個結點的首地址。 內存管理包括一個分配內存的mm_request(unsigned int)函數,一個初始化所要管理的內存的mm_init()函數,一個空閑列表排序函數sort(),一個釋放內存的mm_release(void* )函數和一個判斷內存是否被占用的IsFree(int)函數。

ThreeColorFLAGs問題最早由E.W.Dijkstra所提出,塔所使用的用語為Dutch Nation FLAG(Dijkstra為荷蘭人),而多數的作者則使用Three-Color FLAG來說明。 假設有一條繩子,上面有紅,白,藍三種顏色的旗子,起初繩子上的旗子顏色并沒有順序,您希望將之分類,并排列藍,白,紅的順序,要如何移動次數才會最少,注意您只能在繩子上進行這個動作,而且一次只能調換兩個旗子。
