嵌入式人機(jī)交互界面開(kāi)發(fā),首先要基于適合的硬件平臺(tái)系統(tǒng)方能實(shí)現(xiàn)其功能,硬件平臺(tái)系統(tǒng)的核心是嵌入式處理器。截止07年全球嵌入式處理器體系結(jié)構(gòu)超過(guò)30個(gè),型號(hào)多達(dá)千種以上。業(yè)界一般將嵌入式處理器分為EMPU(嵌入式處理器)、MCU(嵌入式微控制器)、DSP(嵌入式數(shù)字信號(hào)處理器)和SOC(嵌入式片上系統(tǒng))四大類(lèi)?,F(xiàn)階段嵌入式人機(jī)交互界面開(kāi)發(fā)主要集中于EMPU中的X86和ARM架構(gòu)的芯片,而ARM架構(gòu)芯片越來(lái)越呈現(xiàn)出強(qiáng)勁的后來(lái)居上的姿態(tài)。在ARM芯片隊(duì)伍里根據(jù)應(yīng)用主要分為消費(fèi)類(lèi)ARM芯片和工業(yè)、汽車(chē)類(lèi)ARM芯片兩大類(lèi)。其中生產(chǎn)消費(fèi)類(lèi)ARM芯片主要有蘋(píng)果公司、高通、三星、英偉達(dá)、菲利普等,生產(chǎn)工業(yè)、汽車(chē)類(lèi)ARM芯片的公司主要包括飛思卡爾、TI等。
選擇適合的嵌入式芯片后,開(kāi)發(fā)人員往往會(huì)根據(jù)需要?jiǎng)?chuàng)建一個(gè)系統(tǒng)功能的模型設(shè)計(jì),模型主要是考慮軟件的數(shù)據(jù)結(jié)構(gòu)、總體結(jié)構(gòu)和過(guò)程性描述,在這個(gè)模型中界面設(shè)計(jì)一般只作為附屬品。接下來(lái)根據(jù)模型硬件層面必須解決系統(tǒng)的燒寫(xiě)與啟動(dòng)、驅(qū)動(dòng)加載、程序調(diào)度、輸入輸出、顯示與控制等一系列基礎(chǔ)問(wèn)題,因此嵌入式人機(jī)交互界面開(kāi)發(fā)人員對(duì)于相關(guān)嵌入式硬件知識(shí)應(yīng)具備足夠的理解與掌握。
