可复用ENC28J60控制IP核开发与验证

Development and Validation of a Reusable Control IP Core for ENC28J60

针对以太网控制器ENC28J60,开发了一款基于Avalon总线的专用控制IP(Intellectual Property)核。设计改变了传统使用SPI控制器加通用I/O口的控制方法,使得对ENC28J60的控制更加简便。IP核经过了充分验证,并在某动态称重数据采集系统应用中工作稳定,运行良好。该设计结构简单,使用方便,为SoPC(System on a Programmable Chip)开发提供了一个高效的以太网接口。

This paper designed a dedicated control IP core based on Avalon bus for Ethernet Controller ENC28J60.Instead of using SPI controller plus general I/O pins,this dedicated control IP （intellectual property） core made it easier to control the ENC28J60.The design was validated thoroughly,and functions well in a weigh-in-motion data acquisition system.It has a simple structure and is easy to use,thus provides an efficient Ethernet interface for the SOPC （system on a programmable chip） design.
