Field Programmable Gate Array - An Overview
Field programmable gate arrays (FPGAs) represent the currently the most popular and also the newest media for designing application specific integrated digital circuits. They contain an array of a large number of programmable sequential and combinational logic elements (called gates, logic blocks or look up tables). The array of such logic blocks, literally a sea of them, is distributed across a digital chip through interconnections that are programmable. This array is surrounded by a programmable input/output blocks.
