1990年代初Intel公司提出PCI(外围设备互连总线)的建议,代替沿用已久的ISA(工业标准体系结构)总线,同时推出奔腾微处理器芯片,使PC机进入64位的新一代产品。不到10年时间,PC机的时钟频率就突破1GHz,为适应CPU频率和速度的增加,外围设备亦应水涨船高。早期PCI运行在
In the early 1990s, Intel Corporation proposed the PCI (Peripheral Component Interconnect Bus) proposal to replace the long-established ISA (Industry Standard Architecture) bus while introducing a Pentium microprocessor chip to enable the PC to enter the next generation of 64-bit products. In less than 10 years, the clock frequency of the PC has exceeded 1GHz. In order to meet the increase of the CPU frequency and speed, the peripheral devices should also be increased. Early PCI runs at
