图象数据采集系统及其ASIC设计

Image Data Acquisition System and its ASIC Design

本文主要介绍图象数据采集卡，特别是其中的ASIC（专用集成电路）设计。专用集成电路是一片4200门的FPGA芯片，通过对内部电路的设计用以完成512×512×8位的二维数据采集。这种电路与系统的设计简化了印制板，实时性和可靠性都得以提高。方案还具有可扩充性和可移植性。

An Image Data Acquisition board design and implementation with emphasis on its ASIC is presented in this paper. The concrete circuit is designed in the form of FPGA. One chip with 4200 gates is designed to fulfill 512×512×8bits data acquisition. The merits of this system are the simplification for PCB design, the enhancement of real-time performance, the good reliability、 expansibility and portability.
