The inherent reprogrammability of Field Programmable Gate Arrays(FPGA)gives them some of the flexibility of software while keeping the performance advantages of Application Specific Integrated Circuit(ASIC).

• FPGA(Field Programmable Gate Arrays ,现场可编程逻辑门阵列)不仅保持了ASIC(Application Specific Integrated Circuit,专用集成电路)的特性,而且它固有的可重复编程性也给数字图像处理技术提供了软件设计上的灵活性。
