基于SOPC的考勤机控制系统设计

Check On Work Attendance Machine control system Based on SOPC

介绍Altera公司提供的SOPC(System On Programmable Chip)解决方案——Nios Ⅱ软核处理器。针对考勤机这一类设备,采用NIOS Ⅱ处理器的最大特点是其可配置性,设计者不必局限于一般的通用的嵌入式处理器如(MS-51、ARM、DSP等),很好的满足了客户的不同需求,缩短了产品的上市时间,从而能快速的占领市场。此外采用SOPC解决方案可以在对产品的PCB进行较小的改动下进行升级改造。

This paper introduce Altera Co. empoldered SOPC（System On Programmable Chip）solution--NIOS II Soft-- core processor. Check on work attendance machine ,to this kinds of equipment？ the best advantage of adopting NIOS Ⅱ processor is the configurablebility. Designer doesn＇t localized current processors like（MS--51, ARM, DSP etc. ） . satisfy the client＇s different？ needs. Shorten time to market. It can take the market fast. Moreover SOPC Solution can update the product with little PCB change.
