實時多任務操作系統(tǒng)(RTOS)是嵌入式應用軟件的基礎和開發(fā)平臺。目前在中國大多數(shù)嵌入式軟件開發(fā)還是基于處理器直接編寫,沒有采用商品化的RTOS,不能將系統(tǒng)軟件和應用軟件分開處理。RTOS是一段嵌入在目標代碼中的軟件,用戶的其它應用程序都建立在RTOS之上。不但如此,RTOS還是一個可靠性和可信性很高的實時內核,將CPU時間、中斷、I/O、定時器等資源都包裝起來,留給用戶一個標準的API,并根據(jù)各個任務的優(yōu)先級,合理地在不同任務之間分配CPU時間。
TOS是針對不同處理器優(yōu)化設計的高效率實時多任務內核,優(yōu)秀商品化的RTOS可以面對幾十個系列的嵌入式處理器MPU、MCU、DSP、SOC等提供類同的API接口,這是RTOS基于設備獨立的應用程序開發(fā)基礎。因此基于RTOS上的C語言程序具有極大的可移植性。據(jù)專家測算,優(yōu)秀RTOS上跨處理器平臺的程序移植只需要修改1~5%的內容。在RTOS基礎上可以編寫出各種硬件驅動程序、專家?guī)旌瘮?shù)、行業(yè)庫函數(shù)、產品庫函數(shù),和通用性的應用程序一起,可以作為產品銷售,促進行業(yè)內的知識產權交流,因此RTOS又是一個軟件開發(fā)平臺。
