IAlteraFPGA简介现场可编程门阵列FPGA是由许多较小的逻辑单元组成的内部阵列，单元间的信号连接通过其周围的布线通道互连实现，逻辑单元及布线通道可由用户现场配置。近几年来，由于微电子技术的迅猛发展，使得FPGA的各项性能指标也大大改进，规模越来越大，功能越来越全，时 About IAlteraFPGA Field Programmable Gate Array FPGAs are internal arrays of many smaller logic cells whose signal connections are made via interconnecting routing channels around them. Logic cells and routing channels are configurable by the user at the site. In recent years, due to the rapid development of microelectronic technology, making the performance of the FPGA has also greatly improved, the scale is bigger and bigger, more and more full-featured
