【摘要】：當(dāng)今，汽車工業(yè)和電子工業(yè)的正在高速發(fā)展，而汽車音響領(lǐng)域同時(shí)也不斷的完善和創(chuàng)新。汽車上運(yùn)用最古老的電子產(chǎn)品便是汽車音響，汽車音響不斷的升級，已由最早先的汽車收音機(jī)變化為娛樂、視聽、導(dǎo)航、通訊、多功能相統(tǒng)一的綜合性多媒體電子系統(tǒng)，也構(gòu)成將來汽車上不可或缺的組成部分。日本ALPINE公司作為世界知名汽車音響生產(chǎn)商之一，依靠其非凡的質(zhì)量保證、優(yōu)易的性價(jià)比在國際市場上占有重要地位。 汽車音響作為汽車的一個(gè)不可或缺組成部件，以保證汽車功能正常使用為前提，提供用戶以高品質(zhì)的聲音體驗(yàn)是汽車音響的主要任務(wù)�，F(xiàn)有ALPINE的汽車音響聲音處理系統(tǒng)是采用NEC V850SG2系列單片機(jī)C語言控制CXD2729Q DSP處理芯片，選取先進(jìn)的數(shù)據(jù)多媒體技術(shù)，包括數(shù)據(jù)信號(hào)處理、數(shù)字聲音合成技術(shù)，具有優(yōu)良的可移植性和可靠性。 本文主要討論ALPINE的DVD，，或稱Digital Versatile Disc(數(shù)字多用途光盤))模塊中童鎖模塊設(shè)計(jì)。DVD模塊是整體系統(tǒng)中一個(gè)非常重要部分，DVD模塊直接與各個(gè)軟硬件和模塊相關(guān)相結(jié)合，運(yùn)用了ALPINE開發(fā)汽車音響軟件必要的技術(shù)。DVD模塊的機(jī)制是播放DVD\MP3\CD給用戶。APP模塊是DVD模塊的應(yīng)用層，用來判斷外部來的命令是否能夠進(jìn)行處理，如果可以處理在發(fā)給DRVL1模塊,在DRVL1模塊轉(zhuǎn)換成具體應(yīng)該做的命令再繼續(xù)向下一層發(fā)命令。程序設(shè)計(jì)依據(jù)SWEPF思想開發(fā)。開發(fā)語言使用NEC V850SG2系列單片機(jī)C語言。
[Abstract]:Nowadays, the automobile industry and electronic industry are developing at high speed, and the field of automobile sound is constantly improving and innovating. The oldest electronic product used in the automobile is the car stereo. The car sound has been continuously upgraded from the earliest car radio to an integrated multimedia electronic system of entertainment, audiovisual, navigation, communication, and multifunction. It also forms an integral part of the future car. As one of the world famous automobile acoustics manufacturers, Japan ALPINE Company relies on its extraordinary quality assurance, and its performance and price ratio occupies an important position in the international market. As an indispensable component of automobile, automobile audio is the main task of automobile audio system, which is based on the premise of ensuring the normal use of automobile function and providing users with high quality sound experience. In the present ALPINE sound processing system of automobile sound, the CXD2729Q DSP processing chip is controlled by C language of NEC V850SG2 series single chip computer, and advanced data multimedia technology, including data signal processing, digital sound synthesis technology, is selected. It has excellent portability and reliability. This paper mainly discusses the design of the child lock module in the ALPINE DVD, (or Digital Versatile Disc (Digital Multipurpose Disc) module. The DVD module is a very important part of the whole system, and the DVD module is directly combined with the hardware and software and the module correlation. The mechanism of DVD module is to play DVD\ MP3\ CD to user. APP module is the application layer of DVD module, which is used to judge whether external commands can be processed. If you can handle the issue in the DRVL1 module, the DRVL1 module is converted to the specific command that should be done before continuing to issue the next command. The program is designed according to the idea of SWEPF. The development language uses NEC V850SG2 series single-chip computer C language.
