The circuit design , focuses on the following hardware modules : power structure environments , a / d , d / a inverter , dsp and embedded cpu ' s communication interface , dsp modules , and so on . the problems and the corresponds solutions which found in the design and debug are discussed , too . at last , the software design is presented in detail , including system booting , initialization of dsp registers , drivers for ad converter and system software 在电路模块分析中，重点介绍了电源环境的构建、语音信号采集/回放( a / d 、 d / a )模块的设计、 dsp与嵌入式cpu通信接口设计以及dsp核心部分设计，并给出了在原理图设计、制板与调试过程中总结的经验。
“ tian jia ” plastic machinery , as a professional plastic platas and machinery manufacturing company in china , has rich technical force , advanced production line and leading designing adility . with the abundant experience from machine - building and plate making for many years , our company absorbed the latest technology in the domestic and international similar fields , did both designing and manufacturing , and then developed the ” tian jia ” serial panels and plates / sheets “天佳塑机”是一家中国塑料板,片材设备的专业制造企业,拥有雄厚的技术力量,先进的工艺设备,具有领先的设计能力.公司结合多年来在机械制造与制板中积累的丰富经验,广泛吸取国内外同类设备的最新技术,开发出更具实用性,经济性和高可靠性的”天佳”系列板,片材挤出成套设备
Nacpro apparel pattern making system has great progress in the intellectualized and humanized operation . original database management mode , intellectualized automatic pattern - making , auto - grading and customized system , entirely opening unlimited basic block library , linkage operation of pattern modifying , substantial mark lib and line lib in the system or setting , point parallel line - cutting grading and 3d re - grading or more - times grading , marker making for traditional textile irregular textile knitted textile , etc . , auto - matching plaid marker making , beds marker making and double - deck bed marker making , automatic marker making which can be modified by hands any time . we do everything to help the users operating conveniently , quickly and economically 随着计算机技术不断发展，在我公司全体员工的努力下， nacpro服装制板排板系统在智能化操作和人性化操作方面的综合能力大大提高，新颖的数据库管理模式智能化的自动打板自动放码及度身定做全开放式的无限量原型板库打样后修改纸样的关联联动操作大量系统和自定义的记号库及线型库码点平行线-切开线多种放码方式相结合并可进行二次多次立体放码传统面料不规则面料针织面料等不同面料的排料方式自动对格排料分床及高低床排料自动排料并可随时与手动相结合的人工可干预智能排料我们所做的一切，都是为了让用户操作得更加方便快捷节约时间节约面料，我们可以肯定地说， nacpro将以其崭新的面貌，无愧成为当今同行业的胜出者。
After half a years application of the first cad system , huanuo could directly receive the sample data by e - mail . the system engages in all of the process in pattern making and grading and parts of marker making and drafting , instead of labors . it dramatically reduces the labor - cost and materials wastes and greatly increases the efficiency and products quality , bring obvious economical and social benefits . as a large - scale enterprise , only one system can not satisfy the needs sufficiently 引进第一套日升服装cad系统以后，经过半年多的使用，华诺公司已经可以通过电子邮件直接从日本接收样板数据全部制板放码及部分排料画皮工作已经由服装cad系统替代了人工，为企业节省了大量的人力物力，大大提高了工作效率和产品质量，给企业带来了明显的经济效益和社会效益。
Because of the benefits they get from the new technology and the efficient and quick service guarantee , huanuo brought in five suits of software and five american wide plotters . so that six plants in huanuo all apply risheng apparel cad system and realized the computerization in pattern making , grading , marker making , drafting , etc . entirely 华诺公司于2003年4月又从日升公司引进了五套软件和五台美国宽幅画图机，这样华诺公司的六个生产车间全部配备了日升服装cad系统，在服装制板放码排料画皮等方面真正全部实现了计算机化。
