总线、前端总线及HT总线(国外英文资料) What is a bus? In microcomputer, buses usually include internal bus, system bus and external bus. The internal bus is between a computer chip inside the external processor, used for chip level interconnection; and the system bus is between the board and the board microcomputer system, used to interconnect the board level; the external bus is total line between computer and peripheral equipment, computer as a device the information and data exchange through the bus and other equipment, it is used to interconnect the device level. What is the front bus: have been mistaken for this noun is but another name for the fsb. We say the FSB refers to the CPU and the motherboard connection speed, this concept is based on the digital pulse signal based on the shock velocity, while the front bus refers to the speed of the speed of data transmission, data transmission due to the maximum bandwidth depends on the width of all at the same time data transmission and data transmission frequency, bandwidth = (bus frequency data width x / 8). The front bus frequency current PC machine can achieve several 266MHz, 333MHz, 400MHz, 533MHz, 800MHz, 1066MHz, 1333MHz, front bus frequency is larger, represents the amount of data transmission between CPU and memory is bigger, more can give full play to the function of CPU. The current CPU technology is developing very fast and the computing speed is increasing very fast. And the large enough front end bus can guarantee enough data to be supplied to the CPU. The lower front end bus will not be able to provide sufficient data to the CPU, thus limiting CPU performance and becoming a system bottleneck. The English name of the front end bus is Front Side Bus, usually represented by FSB. It is the bus that connects the CPU to the Beiqiao chip. Buy motherboard and CPU, to the attention of both collocation problem, in general, if the CPU is not overclocking, then the front side bus is determined by the CPU, if the motherboard does
