Description
Technical field
The present invention relates to information electron trade millimetre-wave attenuator technical field; Relate in particular to and a kind ofly carry out the millimeter waveguide communication system of point-to-point transmission transfer of data through millimeter waveguide, this millimeter waveguide communication system can be used as the bus of high speed data transfer between processor and the memory.
Background technology
Traditional calculating machine hardware components is general and mature technique based on three kinds: silicon is used to form the transistor, memory and the signal amplifier that carry out logical operation; Composite material is used for the integrated isolation of discrete component; Copper is used for transfer of data.The appearance of polycaryon processor, the parallel and execution simultaneously of instruction adds the development of Optimization Software, and the performance of computer is improved constantly, and computer hardware is also had higher requirement.
For CMOS complementary metal-oxide-semiconductor (CMOS) transistor fabrication, do not have more effective and more economical replacement scheme at present based on silicon.And the research and development progress of composite material also relatively slowly.And the transmission of data becomes the principal element of limiting computer performance.For on the sheet with plate on high speed data transfer, when signal rate near 10 * 10
9B/s, inherent characteristics such as the skin effect of transmission line and self inductance effect begin significantly.More difficult differentiation the between the bit of transmission, the probability of correct decoding reduces, and the synchronous signal integrality worsens serious.Along with the transmission on transmission line, square wave can broaden and die down.Sometimes the effect of dispersion of substrate can be stronger than copper transmission line self chromatic dispersion, limited systematic function more.The distance that these factors make copper cash be used to transmit reduces greatly.Usually, these problems can wait through predistortion, active amplitude equalizer and clock recovery and remedy.But being used for the circuit module of clock recovery, active equalizer and preprocessor can corresponding increase power consumption.In addition, in order to obtain higher throughput, also be infeasible through the width that increases the copper bus merely.Because the increase of highway width, number of channels are lowered and the increase of power consumption, need the increase of the input/output end port of ground connection simultaneously.
A potential selection of instead of copper bus is the light bus.Perhaps the signal of certain wave band is not had on the polymer waveguide of pernicious decay or distortion at multimode fiber, the transmission range of signal can reach several centimetres even several meters far away.But single-bit consumes more energy during the transmission of light bus data.Though new lasing light emitter can directly be modulated to 30 * 10
9About b/s, and enough reliabilities are arranged.But that does like this is arm and a leg, and possibly bear uncertainty.The most important thing is that the light bus does not still have can ripe integrated technique large-scale production, reliable and economic.
