经过10年多一点的时间,现场可编程门阵列的应用日益广泛,现在终于超过了标准的掩模编程的门阵列.器件结构的最新进展还使现场可编程门阵列(FPGA)的门数接近于10万个,可与中等密度的门阵列匹敌.前几代的FPGA一般只能取代2万个门以下的门阵列.为了使FPGA的集成度和性能提高到新的水平,FPGA厂家积极地改善器件密度和门的利用率,减少逻辑延迟,节约成本.这使FPGA既达到理想的性能,而其价格又能与掩模式门阵列进行有力竞争.但由于可编程器件结构很多,因而很难把FPGA与衍生的复杂可编程逻辑器件(CPLD)区分开来.FPGA和CPLD确切来说有些什
After more than a decade, Field Programmable Gate Arrays (FPGAs) have become more widely used and now exceed standard mask-programmed gate arrays. Recent advances in device structures have also brought the number of FPGAs closer At 100,000, it is comparable to a medium-density gate array, which typically replaced only the gate array of 20,000 gates or less in order to raise the level of integration and performance of FPGAs to a new level. FPGA manufacturers aggressively Improved device densities and gate utilization, reduced logic latency and cost savings enable FPGAs to achieve both ideal performance at competitive prices with masked gate arrays, but are difficult to program due to the large number of programmable devices Differentiating FPGAs from Derived Complex Programmable Logic Devices (CPLDs)
