【摘要】：随着电子技术和计算机科学的发展，DSP(数字信号处理)得到了广泛的应用，涉及的领域包括：电力、通信、电机控制、图像处理、计算机、网络以及家用电器等。作为电子工业领域增长最快的产品之一，DSP从问世以来自身得到了很大的提高和改进，，并且技术成本降低，使其拥有广泛的市场前景。随着工艺水平的不断进步，技术的不断提高，DSP不仅达到了高性能，同时成本越来越低，稳定性越来越好，这使得其符合人们的需要，在电机控制领域被广泛应用。而对于DSP来说，外围电路中的事件管理器起着至关重要的作用，直接影响着DSP的运转速度和精度等。本课题设计的是一个用于工业领域的DSP中的事件管理器模块，在研究了事件管理器中的各个功能之后，发现该系统实现简单，电压利用率高，实时性强，有效地提高了机器的运动性能。本课题采用了逆向提取的方法对DSP芯片TMS320LF2407进行了分析。通过逆向工程，介绍了该芯片事件管理器模块的基本原理，其中包括通用定时器，全比较单元，正交编码脉冲输入电路单元，捕获单元，以及中断，之后对各个模块进行了整理和模块化，并进行模块仿真以及整体电路验证，仿真结果表明提取电路性能符合设计要求。本课题采用Charted0.35um BiCmos工艺，对硬件系统方案进行分析，设计了一个高速，高精度的事件管理器，通过编写相应的Veriloge代码和与ModuleSim软件的结合使用，进行仿真，最终达到设计要求。
[Abstract]:With the development of electronic technology and computer science, DSP (Digital signal processing) has been widely used in the fields of electric power, communication, motor control, image processing, computer, network and household appliances. As one of the fastest-growing products in electronic industry, DSP has been greatly improved since it came into being, and the cost of technology has been reduced, which makes it have a broad market prospect. With the development of technology, DSP not only achieves high performance, but also has lower cost and better stability, which makes it meet the needs of people and is widely used in the field of motor control. For DSP, the event manager in the peripheral circuit plays an important role, which directly affects the speed and accuracy of DSP. In this paper, an event manager module is designed for industrial DSP. After studying the various functions of event manager, it is found that the system is simple, high voltage utilization and real-time. The motion performance of the machine is improved effectively. In this paper, the reverse extraction method is used to analyze the DSP chip TMS320LF2407. Through reverse engineering, the basic principle of the chip event manager module is introduced, which includes general timer, full comparison unit, quadrature coded pulse input circuit unit, capture unit, and interrupt. Then the modules are arranged and modularized, and the module simulation and the whole circuit verification are carried out. The simulation results show that the performance of the extraction circuit meets the design requirements. In this paper, the Charted0.35um BiCMOS process is used to analyze the hardware system scheme, and a high speed and high precision event manager is designed. By writing the corresponding Veriloge code and combining with the ModuleSim software, the design requirements are finally achieved.
