一種實用的單片機雙cPU設(shè)計方案及其應(yīng)用:針對傳統(tǒng)儀表具有的硬件資源不足、速度慢等功能缺陷,提出了一種基于單片機的cPU設(shè)計方案,即擴展cPU,直接從主cPU對應(yīng)的數(shù)據(jù)顯示I/O口上獲取數(shù)據(jù),這種獲取數(shù)據(jù)的雙cPU設(shè)計方案中主從cPU之間在功能上相互獨立,主cPU不受擴展cPU加入的影響,實現(xiàn)其固有功能,保證了測量數(shù)據(jù)的準(zhǔn)確性;擴展cPU從主cPU中獲取數(shù)據(jù),不受主cPU的控制,按照現(xiàn)場的需求進行功能擴展。給出了詳細(xì)的軟硬件設(shè)計結(jié)構(gòu)。該方案為傳統(tǒng)儀表的升級改造提供了一種新思路,實踐證明是可行的。關(guān)鍵詞: 傳統(tǒng)儀表 檢測系統(tǒng) 單片機
