Implementations of a Multichannel Digital PWM controller Based on Avalon Bus

设计了一种可应用于片上可编程系统的多通道数字PWM控制器。该控制器基于Avalon片内总线技术,符合该总线的读写传输时序,具有完备的PWM输出能力。控制器用原理图输入与Verilog HDL语言混合设计的方法在Cyclone II系列的EP2C5F256C6现场可编程控制器上实现。实验表明,这种PWM控制器具有很高的可重用性,更易于调试和实现多通道控制,并可应用于任何支持Avalon片内总线的片上可编程系统上。

This thesis introduces a design of multi - channel digital PWM controller that can be used with on - chip programmable system. The controller having complete PWM output capacity. It based on the Avalon on - chip bus technology and accord with its transmission timing. This controller is complemented on the Cyclone Ⅱ FPGA of EP2CSF256C6. It is shown that the PWM controller has a high reusability, easy to debug and realizing multi - channel controlling and can be applied to any on - chip programmable system which support Avalon bus.
