The multi - channel digital synchronized log ( mdsl ) is a high - tech product of the institute of image and graphics of sichuan university , which is used for recording large amounts of real - time multi - channel voices and radar data , such as 16 , 32 or 64 channel ' s data and thus is regarded as the typical real - time computer system “多通道數(shù)字同步記錄儀” ( mdsl )是四川大學(xué)圖像圖形研究所研制的用于實時記錄多個語音和雷達通道資料的高科技產(chǎn)品。該產(chǎn)品要求在記錄語音和雷達數(shù)據(jù)時必須嚴(yán)格時間同步,在不同的數(shù)據(jù)流量下不允許數(shù)據(jù)的丟失,因此該設(shè)備是典型的實時計算機系統(tǒng)。
