摘　　要：本文介绍一种既有PLD的性能与特点、又有FPGA的高密度和灵活性的在系统可编程逻辑器件——ispLSI器件;并以在屏幕上产生视场限定标志为例说明了用它实现图象合成的方法,及其在视频图象测量中的应用。实验证明,ispLSI器件的应用使视频图象测量系统的可靠性和稳定性得以提高。In this paper,the in-system programmable Large Scale Integration (ispLSI) device is introduced. It combines the performance and ease of use of PLDs with the density and flexibility of FPGAS. This device can be electrically erased and has exact pin-to-pin delay. It also provides a security cell to prevent unauthorized copying of the array patterns. Its application in the video frequency measurement is discussed. In this system, this device is used to generate the sign of definition of the visual field. It is capable of proof that using the ispLSI device can increase the reliability and stability of the system.
