可编程DMA控制器IP设计

The IP Design of Programmable DMA Controller

参数化可重用的IP作为新的设计方向，为实现片上系统提供了必要基础，同时建立IP库将为今后的设计节省大量时间和资金。而8位PDMAC的IP设计对于这方面的探索有着重要意义。文章介绍了IP的电路逻辑设计，电路的功能仿真、综合、后仿真和实现等过程。设计的结果表明，这种设计方法对于加快我国的微电子业的进步有一定推动作用。

IP as a new design manner, the features of programmability and reusability makes it possible to integrate asystem into a chip. Building a IP library can save much time and fund. We can explore this method by the IP designing of a 8-bit PDMAC. this paper introduces logic design,functional si miulation, synthesis, post-simulation and implementation of the IP's circuit. This case shows us that this method can do benefit to accelerate the micro-electronic industryin our country.
