基于Niosll步进电机控制器IP核的设计与实现

摘要

根据Nios Ⅱ处理器的Avalon总线规范,设计了一款面向步进电机的控制器IP核。该定制IP核采用软、硬件协同设计的方法,功能符合Avalon总线的读写传输时序,具有完备的步进电机驱动能力。仿真结果表明,该IP核具有很好的可重用性,利于开源共享提高开发效率%According to the Nios Ⅱ’s Avalon bus specification,the paper introduces the design of a stepping motor controller IP core.The method uses collaborative design of software and hardware of custom components to achieve stepping motor controller IP core.The controller agrees with the read and write transmission timing of the Avalon bus and has complete driving capacity.The simulation results show that the IP core has good reusability and efficiency and can be shared
