摘要
为了实现PWM通道数的扩展,提出了一种基于DSP和CPLD的控制器的设计方案,并完成了系统的软硬件设计。该系统的硬件部分主要完成DSP与CPLD之间的数据传输接口设计,软件部分主要采用Verilog语言对CPLD进行编程,能够完成PWM通道数的扩展。实际应用表明,该方案具有操作简便,实时性高的特点,达到设计的要求。
In order to achieve the expansion of the number of PWM channels,the design of controller based on CPLD and DSP is designed in this paper.The hardware system is used to design data transfer interface between DSP and CPLD.Software part mainly for programming the CPLD with the Verilog language, able to complete the expansion of the number of PWM channels. The experiment and application show that this test system has good performance,and achieve the design requirement.
