高密度可编程逻辑器件的出现,混淆了软、硬件两个范畴的界限。虽然由芯片支援系统内部更新升级已经有十多年的历史,但能赖以解决可重新配置系统难题的其他器件至今还是举步维艰。 The emergence of high-density programmable logic devices, confused the boundaries of the two categories of software and hardware. Although it has been more than a decade since the system was internally updated and upgraded by the chip support system, other devices that can solve the problems of reconfigurable systems are still in a dilemma.
