產(chǎn)品詳情
源程序模擬器是在廣泛使用的、人機(jī)接口完備的工作平臺(tái)上,如小型機(jī)和PC,通過軟件手段模擬執(zhí)行為某種嵌入式處理器內(nèi)核編寫的源程序測(cè)試工具。簡(jiǎn)單的模擬器可以通過指令解釋方式逐條執(zhí)行源程序,分配虛擬存儲(chǔ)空間和外設(shè),供程序員檢查;的模擬器可以利用計(jì)算機(jī)的外部接口模擬出處理器的I/O電氣信號(hào)。不同檔次和功能模擬器工具價(jià)格差距巨大。
模擬器軟件獨(dú)立于處理器硬件,一般與編譯器集成在同一個(gè)環(huán)境中,是一種有效的源程序檢驗(yàn)和測(cè)試工具。但值得注意的是,模擬器畢竟是以一種處理器模擬另一種處理器的運(yùn)行,在指令執(zhí)行時(shí)間、中斷響應(yīng)、定時(shí)器等方面很可能與實(shí)際處理器有相當(dāng)?shù)牟顒e。另外它無法和ICE一樣,仿真嵌入式系統(tǒng)在應(yīng)用系統(tǒng)中的實(shí)際執(zhí)行情況。
4.實(shí)時(shí)多任務(wù)操作系統(tǒng)
實(shí)時(shí)多任務(wù)操作系統(tǒng)(RTOS)是嵌入式應(yīng)用軟件的基礎(chǔ)和開發(fā)平臺(tái)。目前在大多數(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(yīng)用軟件分開處理。RTOS是一段嵌入在目標(biāo)代碼中的軟件,用戶的其它應(yīng)用程序都建立在RTOS之上。不但如此,RTOS還是一個(gè)可靠性和可信性很高的實(shí)時(shí)內(nèi)核,將時(shí)間、中斷、I/O、定時(shí)器等資源都包裝起來,留給用戶一個(gè)標(biāo)準(zhǔn)的API,并根據(jù)各個(gè)任務(wù)的優(yōu)先級(jí),合理地在不同任務(wù)之間分配時(shí)間
