1.2.1  UC/OSⅡ操縱系統(tǒng)簡介
      點(diǎn)膠機(jī)控制系統(tǒng)采用UC/OSⅡ操縱系統(tǒng)，相比其他的操縱系統(tǒng)，UC/OSⅡ具有以下特點(diǎn)：
1公然源代碼。整個內(nèi)核大多采用C語言編寫，同時有具體的注解，很適合研究與開發(fā)之用。
2可移植性。內(nèi)核采用移植性很強(qiáng)的ANSIC編寫，只有和微處理器硬件相關(guān)的那部分是用匯編語言寫的。匯編語言寫的部分已經(jīng)壓到zui低限度，使得UC/OSⅡ便于移植到其他微處理器上。
3可固化。UC/OSⅡ是為嵌進(jìn)式應(yīng)用而設(shè)計(jì)的，這就意味著，只要具有固化手段，UC/OSⅡ便可以嵌進(jìn)到讀者的產(chǎn)品中成為產(chǎn)品的一部分。
4可裁減。用戶可根據(jù)需要只使用UC/OSⅡ中應(yīng)用程序需要的那些系統(tǒng)服務(wù)，這樣可以減少產(chǎn)品中UC/OSⅡ需要的存儲空間。
5多任務(wù)。UC/OSⅡ可治理641C31224G01西屋個任務(wù)，其中8個留給系統(tǒng)用。應(yīng)用程序zui多可以有56個任務(wù)。賦予每個任務(wù)的優(yōu)先級必須是不同的，這意味著UC/OSⅡ不支持時間片輪轉(zhuǎn)調(diào)度法—該調(diào)度法適合于調(diào)度優(yōu)先級同等的任務(wù)。
6穩(wěn)定與可靠性。UC/OSⅡ是基于UC/OS的，UC/OS是自1992年以來有數(shù)百個貿(mào)易應(yīng)用，是一個可靠性與穩(wěn)定性*的系統(tǒng)。
7.1.2.2  uC/ OS—II操縱系統(tǒng)的移植
實(shí)際上將uC/ OS—II 移植到ARM 處理器上,需要完成的工作主要是以下三個與體系結(jié)構(gòu)相關(guān)的文件：OS CPU.H，OS CPU.C 以及OS CPU A.S。
OS CPU. H 的移植，文件OS CPU. H 中包括了用# define 語句定義的與處理器相關(guān)的常數(shù)、宏以及類型。 移植時主要修改的內(nèi)容有：與編譯器相關(guān)的數(shù)據(jù)類型的設(shè)定；用#define 語句定義2 個宏開關(guān)中斷；根據(jù)堆棧的方向定義OS STK GROWTH等。
      在將uC/ OS - II 移植到ARM 處理器上時,首*行基本配置和數(shù)據(jù)類型定義。重新定義數(shù)據(jù)類型是為了增加代碼的可移植性,由于不同的編譯器所提供的同一數(shù)據(jù)類型的數(shù)據(jù)長度并不相同,例如int型,在有的編譯器中是16 位,而在另外一些編譯器中則是32 位。所以,為了便于移植,需要重新定義數(shù)據(jù)類型,如INT32U 代表無符號32 位整型。typedefunsigned int INT8U ,就是定義一個8 位的無符號整型數(shù)據(jù)類型。其次就是對ARM 處理器相關(guān)宏進(jìn)行定義,如ARM處理器中的退出臨界區(qū)和進(jìn)進(jìn)臨界區(qū)的宏定義,退出臨界區(qū)宏定義[5 ] : # define OS EXITCRITICAL () ARMDisable Int ( ) / / 關(guān)中斷,進(jìn)進(jìn)臨界區(qū)宏定義# define OS ENTER CRITICAL ( ) AR2MEnableInt () / / 開中斷. zui后就是堆棧增長方向的設(shè)定. 當(dāng)進(jìn)行函數(shù)調(diào)用時,進(jìn)口參數(shù)和返回地址一般都會保存在當(dāng)前任務(wù)的堆棧中,編譯器的編譯選項(xiàng)和由此天生的堆棧指令就會決定堆棧的增長方向,定義為# define OS STK GROWTH 1.
     OS CPU. C 的移植包括任務(wù)堆棧初始化和相應(yīng)函數(shù)的實(shí)現(xiàn). 在這里,共有6 個函數(shù):OSTaskStkInit( ) , OSSTaskCreateHook ( ) , OSTaskDelHook ( ) , OS2TaskSwHook( ) ,OSTaskStatHook ( ) , OSTimeTickHook () 。其中后面的5個HOOK函數(shù)又稱為鉤子函數(shù),主要是用來對uC/ OS - II 進(jìn)行功能擴(kuò)展。這些函數(shù)為用戶定義函數(shù),由操縱系統(tǒng)調(diào)用相應(yīng)的HOOK函數(shù)往執(zhí)行,在一般情況下,他們都沒有代碼,所以實(shí)現(xiàn)為空函數(shù)即可。而函數(shù)OSTaskStkInit( ) 對堆棧進(jìn)行初始化,在ARM 系統(tǒng)中,任務(wù)堆棧空間由高到低依次為PC ,LR ,R12 ,R11 , ?,R1 ,R0 ,CPSR ,SPSR. 在進(jìn)行堆棧初始化后,OSTaskStkInit ( )返回新的堆棧棧頂指針. 
    OS CPU A. S 文件的移植需要對處理器的寄存器進(jìn)行操縱,所以必須用匯編語言來編寫。這個文件的實(shí)現(xiàn)集中體現(xiàn)了所要移植到處理器的體系結(jié)構(gòu)和uC/ OS - II 的移植原理。 它包括4 個子函數(shù):OSStartHighRdy() , OSCtxSw() , OSIntCtxSw() ,OSTick2ISR()。其中難點(diǎn)在于OSIntCtxSw() 和OSTickISR() 函數(shù)的實(shí)現(xiàn),由于這兩個函數(shù)的實(shí)現(xiàn)與移植者的移植思路以及相關(guān)硬件定時器、中斷寄存器的設(shè)置有關(guān).在實(shí)際的移植工作中,這兩處也是比較輕易出錯的地方。
      OSIntCtxSw( )函數(shù)由OSIntExit( )函數(shù)調(diào)用,而OSIntExit()函數(shù)又由OSTickISR() 調(diào)用. OSIntCtxSw()函數(shù)zui重要的作用就是它完成在中斷ISR中直接進(jìn)行任務(wù)切換,從而進(jìn)步了實(shí)時響應(yīng)的速度. 它發(fā)生的時機(jī)是在ISR 執(zhí)行到OSIntExit ( )時,假如發(fā)現(xiàn)有高優(yōu)先級的任務(wù)由于等待time tick 的到來獲得了執(zhí)行• 7 2 • 第4 期李學(xué)橋等:uC/ OS - II 在ARM系統(tǒng)上的移植與實(shí)現(xiàn)的條件,就可以馬上被調(diào)度執(zhí)行,而不用返回被中斷的那個任務(wù)之后再進(jìn)行任務(wù)切換. 實(shí)現(xiàn)OSIntCtxSw() 的方法大致也有兩種情況[7 ] :一是通過調(diào)整SP 堆棧指針的方法,根據(jù)所用的編譯器對于函數(shù)嵌套的處理,通過精確計(jì)算出所需要調(diào)整的SP 位置來使得進(jìn)進(jìn)中斷時所作的保護(hù)現(xiàn)場的工作可以被重用. 二是設(shè)置需要切換標(biāo)志位的方法,在OSIntCtxSw( ) 里面不發(fā)生切換,而是設(shè)置一個需要切換的標(biāo)志,等函數(shù)嵌套從進(jìn)進(jìn)OSIntExit( )= >OS ENTER CRITI2CAL()= >OSIntCtxSw( )=>OS EXIT CRITICAL()=> OSIntExit( )退出后,再根據(jù)標(biāo)志位來判定是否需要進(jìn)行中斷級的任務(wù)切換。
其次是對OSTickISR() 修改。OSTickISR() 首先在被中斷任務(wù)堆棧中保存CPU 寄存器的值,然后調(diào)用OSIntEnter()。隨后調(diào)用OSTimeTick()，檢查所有處于延時等待狀態(tài)的任務(wù),判定是否有延時結(jié)束停當(dāng)?shù)娜蝿?wù)。zui后調(diào)用OSIntExit( )。假如在中斷中(或其他嵌套的中斷)有更高優(yōu)先級的任務(wù)停當(dāng),并且當(dāng)前中斷為中斷嵌套的zui后一層,OSIntExit( )將進(jìn)行任務(wù)調(diào)度。假如進(jìn)行了任務(wù)調(diào)度,OSIntExit()將不再返回調(diào)用者,而是用新任務(wù)的堆棧中的寄存器數(shù)值恢復(fù)CPU 現(xiàn)場,然后實(shí)現(xiàn)任務(wù)切換。假如當(dāng)前中斷不是中斷嵌套的zui后一層,或中斷中沒有改變?nèi)蝿?wù)的停當(dāng)狀態(tài), OSIntExit ( ) 將返回調(diào)用者OSTickISR      ( ) ,OSTickISR() 返回被中斷的任務(wù). zui后就是退出臨界區(qū)和進(jìn)進(jìn)臨界區(qū)函數(shù). 進(jìn)進(jìn)臨界區(qū)時,必須封閉中斷,用ARMDisableInt () 函數(shù)實(shí)現(xiàn). 在退出臨界區(qū)的時候恢復(fù)原來的中斷狀態(tài),通過ARMEnableInt ( ) 函數(shù)來實(shí)現(xiàn)。至于進(jìn)行任務(wù)級上下文切換,則是由匯編子程序OSCtxSw 實(shí)現(xiàn)。
