【摘要】 近几年来,嵌入式技术随着集成电路技术和计算机技术的发展而日渐普及,在医疗、电子等领域发挥着很重要的作用,具有重要的意义。ARM Cortex-M3处理器是行业领先的32位嵌入式处理器,适用于具有高确定性的实时应用,已专门开发为允许合作伙伴为范围广泛的设备(包括微控制器、汽车车体系统、工业控制系统以及无线网络和传感器)开发高性能低成本的平台。该处理器提供出色的计算性能和对事件的卓越系统响应,同时可以应对低动态和静态功率限制的挑战。该处理器是高度可配置的,可以支持范围广泛的实现(从那些需要内存保护和强大跟踪技术的实现到那些需要极小面积的对成本非常敏感的设备)。喷气织机是现代无梭织机中速度最快的一类织布机,具有性能好而维修工作量及费修费用低、引纬率高的性能的特点,在整个织布机发展市场中,具有重要的地位。将嵌入式Cortex-M3处理器应用到喷气织机的引纬控制,一方面可以减少产品成本,同时也对提高我国的中高档喷气织机的技术水平有重要意义,对其他无梭织机的研发具有重要的参考意义。论文的主要研究内容主要包括硬件和软件设计2个方面。硬件主要是以Cortex-M3内核为中心的主板、电源板以及驱动板的设计；软件主要是利用MDK软件进行编程,采用工艺圆原理实现控制织机引纬的功能。更多还原

【Abstract】 Embedded technology plays a more important role in medical treatment and electronic aspects with the development of integrated circuit and computer technology in recent years. ARM Cortex-M3 processor is kind of advanced processor. It adapts high real-time application and it is allowed the cooperation partner to develop widely used equipment, including microprocessor, cars system, industry control and wireless network and sensors with the low cost comparing with the high performance. The processor provides excellent computing capability and quick response to event, as well as it can challenge the low dynamic and static power. The processor can be configured freely and support wide realization from those that need memory protection and strong trace technology to those that require small area and are sensitive to cost.Air-loom is one of the fast modern shuttle less loom. It has good capability, low maintain cost and high weft rate. During the whole loom market, it has a stage position. Using Cortex-M3 processor into air-loom weft control system. On one hand, it can reduce product cost, on the other hand, it has a important meaning for improving our nation’s middle and high level air-loom technology, as well as a reference for other shuttle less looms.This paper mainly includes two parts:hardware design and software design. The hardware aspect is about the main board based on Cortex-M3, power circuit board and drive board. The software aspect is mainly about using craft circle method to realize the weft control of air-loom using MDK software.更多还原
