According　to　the　developmental　trend　of　modern　automobile　instrument,　this　paper　puts　forward　a　multifunctional　digital　instrument　based　on　the　embedded　Linux　system.　The　digital　instrument　panel　consists　of　embedded　microprocessor　and　contact　screen,　and　it　could　not　only　receive　and　process　all　kinds　of　driving　information　from　peripheral　interface　and　display　the　results　on　the　LCD,　but　also　has　the　function　of　aided　parking.　This　paper　proposes　an　integrated　design　solution　for　the　digital　instrument.　The　design　selects　the　TI＇s　TMS320DM355,　which　includes　LCD　and　contact　screen　module,　CAN　bus　module,　LIN　bus　module,　video-in　and　audio-out.　The　digital　instrument　can　receive　real-time　data,　and　also　process　the　data　and　store　it　in　the　RAM　and　display　all　vehicle　operating　parameters　in　the　LCD　and　realizes　real　time　monitoring　in　backing　up.　Based　on　the　experiment,　it　is　proved　that　the　designed　system　reaches　the　primary　design　specifications.
