The traditional answering machine has much inconvenience when the telephone number is unknown.This paper designs a multi-function answering machine out of this reason.Considering FPGA has the configurability,scalability,integrated IP core to facilitate the completion of system on chip（SOC） design as well as advantages such as low cost,high speed,short time to market,the system is completed based on FPGA and soft core（NIOSⅡ）.The system is designed by SOPC custom and co-design method,where the frequency is 50MHz.Image acquisition and JPEG compression can be completed within 2 min.The system communicates with users through touch screen.Voice message,message prompts,electronic key,user management（play,view history,notes,and delete,etc.）,electronic clock,voice broadcast,automatic standby and screen savers and other features are within the work. 可编程逻辑器件（FPGA） NIOSⅡ 留言机 JPEG图像压缩 FPGA NIOSⅡ answering machine JPEG 10.14188/j.1671-8836.2011.03.006 TN791 国家高技术研究发展计划（863）项目（2008BAC36B05） 2011-03-01 2021-04-01 3 57
