Technical Field

The present application relates to the field of bus technology.

Background technique

The development history of the bus includes the early PC (Program Counter) bus and ISA (Industry Standard Architecture) bus, PCI (Peripheral Component Interconnect)/AGP (Accelerated Graphics Port) bus, PCI-X bus and the mainstream PCI Express and HyperTransport high-speed serial bus. From PC bus to ISA and PCI bus, and then from PCI to PCI Express and HyperTransport system, the computer has also completed three leaps in these three major transitions. Corresponding to this process, the computer's processing speed, implemented functions and software platform are also undergoing the same evolution. In the computer system, each functional component is addressed through the address bus. The speed of the bus has a great impact on the system performance. Because of this, the bus is known as the nerve center of the computer system, but compared with the CPU (Central Processing Unit), graphics card, memory, hard disk and other functional components, the improvement of bus technology is much slower. In the more than 20 years of computer development, the bus has only been updated three times, but each change has given the computer a new look. Today, in the era of artificial intelligence computing based on big data and cloud computing, the existing "storage wall" problem is more prominent, and the von Neumann architecture requires frequent data exchange, which brings about bandwidth, latency and power consumption problems. The actual root cause is that the backward electronic bus has become a bottleneck limiting computing power.

During the implementation process, the inventors found that there are at least the following problems in the conventional technology: the current electronic bus has the problem of low transmission performance.

It should be noted that compared with electrons, millimeter waves as information carriers have inherent advantages: ultra-high speed, ultra-high bandwidth, and ultra-low loss. For example, millimeter waves, centimeter waves, and Sub-6GHz, etc., have extremely fast response times in electromagnetic waves when transmitting information. The information rate can reach tens of Tb/s, and the performance can be improved by hundreds of times. Secondly, millimeter waves and centimeter waves have extremely high information capacity, which is 3 to 4 orders of magnitude higher than electrons, and can achieve low switching delay and high transmission bandwidth.
