对服役多年达到使用寿命的电子装备，采用现场可编程门阵列（FPGA）集成电路技术进行技术改造，既能保证装备原有的技术性能指标，又可提高装备的可用性、维修性及可靠性．介绍了采用FPGA技术对某型数字式指挥仪进行技术改造的方法，并表明这种方法是装备技术保障中的一种行之有效的技术措施．
For electronic equipment that has been in service for many years and has reached the end of its useful life, the use of field programmable gate array (FPGA) integrated circuit technology for technological innovation will not only ensure the original technical performance of equipment, but also improve the availability, maintainability and reliability of the equipment. The method of using FPGA technology to transform a certain type of digital commanding instrument is introduced. And it shows that this method is an effective technical measure in the technical support of equipment.
