摘要
针对在系统编程中存在的一些问题,当通信设备在局方正式运行后,通过采用将配置芯片EPROM带到现场更换等硬件升级、维修技巧,解决了现场复杂可编程逻辑器件(CPLD)升级难题。研究结果表明该技术提高了产品现场服务响应速度和服务质量。
Aiming at the problems in ISP-In-System Program, the spot replacement method of the EPROM was employed during the realizing of the upgrade of field programmable gate（FPGA）. However, the field upgrade of complex programmable logic de- vice（CPLD） is hard to achieve. The solutions for the CPLD upgrade problems were presented. The results indicate that the re- sponse speed and the quality of services are improved with the adoption of these solutions.
